Positioning The Camera

It’s a cold rainy summer morning….so dark I keep thinking I have my sunglasses on. I’ve cranked open the library windows and faced the camera toward the Serviceberry tree. My rig is positioned farther from the windows than usual because if it wasn’t, the 500mm lens would be too close to focus on the nearest berry branches. (NOTE: Minimum focusing distance =  12.4′ or 145.7″). The portable heater is resting on a book to insure that the floor under which it sits does not vibrate the camera. I positioned the lens to capture (as the bird’s background) a multilayered forest of feathery ferns huddling just beyond the Serviceberry tree. The f/9 aperture setting will transform a few of those individual fronds into lush, polished buttery green swirls.

Photographing Two Cedar Waxwings

Birds constantly forage, even in the wettest and coldest of conditions. The bolder, familiar frugivores in our yard (Jays, Catbirds, Robins, Titmice, Nuthatch, Woodpeckers, Finches, many of them tending to their fledglings) swarm the Serviceberry tree, acrobatically maneuvering to pluck the ripe berries at the ends of the branches.

I can see Cedar Waxwings in the distance. They are cautious, watching me, coming in a little closer and then doubling back for safer grounds. They are better at waiting and watching than I am- and I’m pretty good.

Cedar Waxwings are nomadic birds and thus do not establish territories. This species is highly social and travels in cooperative flocks – moving often from one place to another and settling down for a short time during breeding season to build nests and raise young. The only way I can reliably find and photograph these fruit eating birds is to look for trees and shrubs that bear small fruits- huckleberry, serviceberry, juniper, hawthorn, cedar, honeysuckle and winterberry. Assuming the fruit is ripe, there’s a good chance that Cedar Waxwings will be found voraciously eating the berries until the bushes are bare.

Flash Limitations

The cedar paths beyond the Serviceberry tree are obstructed with thick foliage, so much so that I no longer can see through the woods to the houses beyond. The only trees that aren’t completely fleshed out are the high in the sky Locust trees. The ostrich ferns have unfurled, no longer reaching. It’s very difficult to get a clear line of sight into the understory trees or through the woods beyond. It’s best to be patient, wait and hope that the birds will perch closer to the camera.

The woodlands in the background are darker than the foreground…almost 2 stops darker. I set the camera to spot metering so E-TTL II is better able to read the light and emit the appropriate amount of flash if the bird happens to be farther off. I have the Beam Concentrating Fresnel attached to concentrate the light beam so it can travel greater distances. (NOTE: This is an essential piece of equipment if you want a flash blast that better fits the angle of view of a long lens. However, a flash extender will not be able to project enough light to the smaller distant birds if they are perched more than 25 feet from the camera.)

Berry Eating Birds

If you want to attract and photograph birds into your yard, plant Serviceberry Trees. If that’s not possible, just search out the locations of the wild berry bushes around you and do a little research to determine when the berries will be ripe. You won’t be disappointed.

Photographing An American Redstart Warbler

It’s been partially sunny with cool refreshing winds for 5 days now and the forecast predicts much the same for the next three days. Tree canopy above the house is fully leafed out. Petals from the tops of the blooming locust trees float into the house onto the carpet. Plants are looking dry and droopy. The few mosquitos I encounter are sluggish.

Squirrels and chipmunks scurry along the cedar mulch paths to the fountain to get a drink from the water flowing down. Titmice and Robins pay me no mind as they bathe and drink from the bubbler. This Spring, a pair of American Redstart Warblers have returned to nest in our yard. The male, adorned in his spring finery, visits the fountain often.

High in the Treetops

Here on ground level, the only warblers we have noticed are the Redstarts. My bird books confirm that 43 wood warblers species nest in MI… most of them arboreal.  An arboreal bird is defined as: “A type of bird that relies on trees and dense foliage, spending much of its life in trees and rarely either descending to the ground or otherwise leaving the cover of the canopy.”

A wide diversity of highly specialized birds and other creatures live in this upper layer habitat created from the crowns of trees. This obscured community rarely needs to venture down to a ground level water source. They drink from the near billions of lighter-than-air floating water droplets carried in the fog and intercepted by tree leaves.

Is it too much to hope that other species of warblers actually live high in our tree canopy and that they might one day come down?

Hope Springs Eternal

I set up my camera, 500mm lens, 1.4 tele extender, and bracketed flash on to the tripod inside the house (with one tripod leg outside on the step of the deck). Sunlight on the deck slowly transitions, uneven and patchy, as the morning sun rises in the sky. I set the focus limiter switch on the lens barrel to restrict the len’s autofocus to 3.7m-10 m.

ISO Settings With Flash

I keep my Canon camera in Manual (M) mode, but set the flashgun to Auto. E-TTL II will compensate as the exposure parameters change with the shifting light. I play around with the ISO settings, raising it to brighten the background. If I leave the camera’s ISO setting in auto mode, the camera automatically sets  ISO to 400 when a flash is attached and activated. (NOTE: There are times when the flash can not recycle fast enough to keep up with the shudder action. If Auto ISO is set, the ISO will rise to compensate and correct exposure when the flash does not fire. If I set the ISO to a specific value, the camera will be in complete manual mode and will not override the aperture, shutter, and  ISO set by the photographer.  In this instance, the camera will still take the shot, but the images will be underexposed.)

Working on Glare Control

Mid day rolls in. The sun is casting glare and shadow and the blinkies are flashing through the viewfinder. I can feel the hot sun on my face as it clears the trees and bears down on the house. The brim of my hat does a good job blocking the sun from my eyes, but whenever I try to place my eye on the eyecup, the hat pushes back on my head, moving the camera and tripod. The hat comes off.

Instead of packing up, I consider inserting the circular polarizer into the lens. Then, possibly I could effectively boost color and contrast in an otherwise washed out scene. The reduction of light with the polarizer inserted sends the ISO soaring. For birds I can only lower the shutter speed so much….so I turn on the flash with extender again. I rotate the polarizer to get the maximum reflection reduction, but the resulting images shone on the LCD screen come back full of glare. The polarizer can not eliminate the glare caused by the elevated flash gun. That beam probably needs its own polarizing sheet. Too much hassle for such a beautiful day. I power down the camera and flash and put everything away.

Photographing a Magnolia Warbler — Battery Maintenance

Thank you for sharing....Digg thisShare on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInShare on StumbleUponPin on PinterestEmail this to someoneShare on Tumblr

Spring Bird Vigil

It’s Spring migration time again. My eyes are continually scanning the outdoors for birds newly arriving or just passing through. I know that I must be missing most of them. If they do venture down to rest and replenish, the vast majority are hidden in the foliage or high in the trees or off in somebody else’s yard. The number of transients that come within my purview–at a time when my camera and I are ready –seems minuscule compared to the billions of birds on the move.

My mind was elsewhere as I swapped out the spent batteries in my Canon 1 DX Mark II camera and set up the camera near the deck. I had spent much of the day behind the viewfinder photographing the familiar birds when a stunning male Magnolia Warbler appeared right in front of my lens. I got off one shot, then nothing. The camera went dead.

No Power

Ack!!!  No power!  And no swappable moment…. the warbler was gone.  I had just changed the battery pack in the morning and couldn’t have taken more than 100 shots during the day. Why did it fail?  It is true that Canon new flagship…the 1 DX Mark II is power hungry, but the newly designed battery pack is supposed to be up to the task. The specs boast that battery pack (less than a year old) will provide up to 1210 shots per charge, optimally. (Battery life for Video = approx 1-1/2 hrs). I do have power hungry functions engaged (flash, focus points, IS, Al Servo auto focus, etc.), but nothing unusual for bird photography.

Frustrated, I swapped out the dead battery with another recharged battery pack and scrolled down to battery info in the menu system. In big red letters at the bottom of the screen it read: Calibration is recommended when charging battery next time.

Battery Calibration

Batteries don’t stay young. Battery calibration is the process of maximizing electrical storage capacity and insuring that batteries hold their charge. It also resets the gauge of the battery freshness indicator to better match the actual power remaining in the battery.

The solution to fast draining batteries is to attach the exhausted battery to the charger and press the calibration/performance button. The charger will go through a calibration procedure which fully discharges any power left in the battery. It then fully recharges it. If you try to calibrate a charged battery, the depleting process takes much longer.

Over the next two days, I re-calibrated both lithium ion batteries. The recharge performance indicator in the camera menu now shows that they both can adequately retain a charge.

It costs $169.00 for a new battery for my camera. From now on, I will pay more attention to battery maintenance.

Photographing White Throated Sparrows -Two Color Morphs

Thank you for sharing....Digg thisShare on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInShare on StumbleUponPin on PinterestEmail this to someoneShare on Tumblr

Photographing White Throated Sparrows

It is a somber morning. As I set up the camera, I’m grateful that the heavy clouds at least provide an evenly lit prospect. The long hanging stems and flowers of the Bleeding Hearts droop and sway with the wind. Small flocks of White Throated Sparrows forage on the ground in our yard….using their anisodactyl toes (3 facing forward and 1 pointing backward) to rake layers of wet leaves and snatch whatever treat surfaces.

Unless I want to get down on my belly with the camera and long lens, capturing ground foraging birds at eye level in their natural environment is not an appealing idea. So I wait for these birds to rise up onto a stump pedestal or into one of the understory trees.

Distinct Color Variations

While tracking the ground foraging birds, I notice that some White-Throated Sparrows have distinctive bright white stripes on their faces and foreheads, while others sport more mellow, creamy versions of the same stripes. With birds, I always assume that the drabber version is a female or immature male. I tend to pick and choose from a group and track the more distinctively colored birds with my camera, especially in the Spring. Consequently I pay less attention and take fewer photos of the birds with lackluster colors.

This time I paid more attention. I noticed that the less distinctive birds are not just drab….but atypical in their coloration. With the help of detailed photos, the two distinct color variations are pronounced enough to make me think that I am photographing two different species. A quick check on line quickly solves the puzzle.

Subspecies v Color Morphs

Subspecies are defined as “distinct populations within a species” that overlap and interbreed in those geographic locations where the two subspecies populations meet. Color Morphs are defined as “distinctly different plumages within a species”.

White Throated Sparrows come in two different color forms. The not so subtle differences in the genetically determined plumage color within this species include:

  • “…….Clean black-and-white head stripes (vs. dark brown/black and pale tan)
  •  unstreaked gray breast (vs. drab gray-brown, streaked and mottled darker)
  •  clean gray cheeks (vs. mottled and washed with brown)
  •  sharply-contrasting clean white throat with clean border (vs. drab white with mottled border and divided by dark lateral throat stripe
  •  brighter and cleaner yellow loral spot (vs drabber)……..”

What is really interesting is that the tan morphed White Throated Sparrows almost always prefer to mate with the white striped individuals and vice versa. Different behavior and breeding habits between the two color morphs have also been documented.

NOTE: Two excellent articles about  White Throated Sparrows are: “A Closer Look At An Ordinary Species” by Smithsonian Migratory Bird Center scientist Brent Horton; and “The Fascinating and Complicated Sex Lives of White throated Sparrows” by Audubon field editor, bird expert, environmentalist, and artist, Kenn Kaufman.

Photographing an Indigo Bunting Framed in Red Bud Flowers

Thank you for sharing....Digg thisShare on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInShare on StumbleUponPin on PinterestEmail this to someoneShare on Tumblr

Photographing an Indigo Bunting

It was a dreary day when I took these photos, and that matters when photographing birds with blue plumage. On a sunny day, you can easily see blue, purple, and aqua hues glimmering on the feathers of male Indigo Buntings. The more light, the more intense the colors appear to be. But it’s really just an illusion. There are no blue pigments in the feathers of Indigo Buntings, or any of the blues we see in nature.

It’s All About Light

Indigo Buntings (and all other birds of blue) are unable to manufacture blue pigments. Pigment is what gives us true color. We see blue only because of the reflective structure of the Indigo Bunting’s feathers. When light waves fall on his feathers, the feather structure breaks the different colors of the light apart. Only blue tones are reflected back out. (The other colors of visible light are absorbed by the feathers.)

You can see in these photos patches of black and brown colors because when there’s little or no light, the feathers of Indigo Buntings are actually all brown and black. I was a little disappointed that the feathers of this male were not more colorful for the camera, but he was sitting amongst glowing Red Bud flowers, and that helped.

Encircling Floral Frames

I love showy flowering Red Bud Trees. The long graceful twigs are wide spread, slim and tender, with heart shaped leaves leaving plenty of room for the camera lens to intrude. Its fruit consist of purplish black pods in which are nested tiny, bird attracting black seeds. These understory beauties are one of the earliest to flower in our shaded yard and consequently attract a lot of migrating avian pollinators. Tiny rosy purple flowers even grow on the Redbud’s bifurcated trunk.

Framing Strategies

Some considerations when framing birds within branches and flowers are:

  • The frame is essentially a wrap around intended to spotlight an eye catching subject and the beauty of its natural surroundings. It should accentuate and complement the subject.
  • You can frame with flowers, shadows, dark patches- any defined area that can serve as an enclosing border. The fewer the distractions, the better.
  • Since you control what your viewer sees,  judicious cropping in post processing is an important part of framing.
  • In addition to accenting and complementing the subject, the frame should give the photo context (in this case Spring).
  • Texture, color and detail add emotion, thus engaging the viewer.
  • Depth of field add to the sense that there’s a frame. Tight depth of field accentuates the front and back. Blurred background and foreground make the frame less noticeable.
  • You can prune and rearrange flowers and foliage to create the perfect perch. If you do not, you will likely have to maneuver the lens to focus tightly within lots of branches.

Attempting to frame a bird in a picture perfect natural setting takes timing and perservance, and no small amount of luck. It’s worth the effort, even on those days when the bird’s plumage colors are muted.

Photographing Baltimore Orioles-The Difference Between Nesting and Roosting

When the Wind Blows, the Cradle Will Rock

At least, the Baltimore Orioles’ nesting cradles will rock.

Nest Building

Watching the Spring courtship and nesting rituals of birds is always invigorating. One of the most conspicuous performances is staged by the blazing yellow and orange Baltimore Orioles. The males display their finery and sing their hearts out in the usual way and pretty soon the females are busy weaving nests made of grass, ferns, leaves, hair, and twine, with feathers for the inner lining. She stitches these building materials together in tangles and knots, using the longest fibers to hang the nest from the outer end of a concealed tree branch. These sock-like hanging nests sway with the wind, but are only really noticeable in the Fall after the tree leaves have dropped. (NOTE:  Each Spring I spread a few dozen short pieces of yarn about the yard, in the basement window wells and near the foot paths, hoping the birds will incorporate them into their nests.  It disappears…. but I’ve never seen these fibers carried by any bird nor incorporated into a nest.)

The Disney Version

Last winter, we spied an Eastern Screech Owl in the owl house we erected 3 years earlier.  How exciting, we thought. Perhaps he is exploring nesting opportunities, hoping to snatch a space to house a future family. After 3 weeks, the owl was gone and we haven’t seen him since.

Time to change my mental model – the wildly inaccurate Disney version of birds sleeping with their families in the nests they find or build.

Nesting is Different than Roosting

Nests are not homes for birds nor are they a place to rest or sleep. Birds who build nests build them to be temporary. They are often a sagging, parasite filled poopy mess after raising one or more broods.

Roosting simply means: “A place where winged animals, especially birds or bats, rest or sleep. 2. A place for temporary rest or sleep”.  Birds use nests seasonally as a place to incubate their eggs and to hide, protect and nurture their young. Once the fledgings have flown the nest, the parents typically abandon them too.

Roosting Places

At night, most birds need a safe place away from roaming nocturnal predators. Some bird species crowd together communally for protection and warmth, while others sleep in secret isolation in some hidey hole, cliff, cavity, porch, barn, bucket, storage container, marshy lowland or high tree top.

Birds who stick around during the day must find places to settle down out of harm’s way for the night. Every time we add to a pile of dense vegetative debris, plant an evergreen, or erect a protective shelter, we are setting up safe places for bird roosting. After all, unlike nesting, sleeping is an essential, nightly, all season behavior.

To attract tired birds, roosting box designs should have the following characteristics:

  • Heat conservation (especially in the winter)
  • Plenty of room and perching spaces within to accommodate more than one bird
  • Cleanable design, with space on the bottom for wood chips
  • Multiple exits to escape predators
  • Entrance/exit holes that are designed to accommodate and protect certain sized birds (so the big and aggressive birds don’t hog all the good spots).

Not too much to ask. We’ve started searching on-line for roosting boxes, especially for the year round birds.

NOTE: This Spring the owl house is empty. The Eastern Screech Owl we observed last winter obviously a found better place to nest….. away from the prying eye of the camera.

Photographing Chipping Sparrows and Thoughts about Computerized Metering

Thank you for sharing....Digg thisShare on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInShare on StumbleUponPin on PinterestEmail this to someoneShare on Tumblr

Photographing Chipping Sparrows

Chipping Sparrows nest in our yard each summer.  They are bold and persistent warbler size sparrows, especially when ground foraging in the yard or at the feeder. During the Spring plumage cycle, the male sports a bright rust cap and a lot of distinguished looking gray, black and brown on his body and long notched tail. Except for the size, Chipping Sparrows look similar to American Tree Sparrows and Clay Colored Sparrows.

Chipping Sparrows are common in our wooded yard. They don’t spook easily while foraging and that gives me time to experiment with the camera. These three photos were taken in different settings, with different backgrounds and at different times of day in order to better understand how the camera’s light meter discerns light.

Computerized Metering

For most photographers, “perfect” exposure depends on how effectively the camera’s light meter analyzes the scene.  When I’m out in the field, my go-to metering mode is Evaluative,  a “smart” system with a multi-level internal light metering system.

The Light Coming Through The Lens

Internal light meters, regardless of the meter mode set, will not read the light falling upon the subject and its surroundings, but only the light reflecting off of them and back through the lens. A black iridescent Crow is not going to reflect back as much light as a Snowy White Egret. A brown tree lined background is not going to reflect the same light as a highly reflective mix of spring colors.

Conditions affecting the light’s direction, intensity, absorption and bouncability also impact how light travels through the lens.  Attach a flash and a whole new level of light meter E-TTL analysis kicks in, gauging the ambient light reflected off of the subject and calculating how much flash is needed to maintain exposure parameters. (NOTE: To read about the physics of how light travels and reflects off an object, visit this link.)

NOTE: You don’t often see bird photographers carrying around hand-held or separately mounted light meters. These exterior meters calculate the amount of light falling on the scene….the “incident” light, not the light reflected back through the lens (TTL).

Light Meter Calculations

Modern in-camera light meters do more than just average the light reflecting back through the lens. The camera’s micro computer divides the scene and separately analyzes each zone. It then weighs the focus point placement, reflectivity, color, distance, and lots of other variables. Too many dark or light tones reflecting back without the balancing act of middle gray shades will throw off your meter and result in overexposed or underexposed images.

(NOTE: The histogram is a reliable way to see how the light meter is balancing the light coming into the lens.)

Restricting the Metering Area

Metering modes tell the camera system WHERE in the scene to meter the reflected light. If you change the metering mode from evaluative (total scene) to partial (approx 6-10% of the area) or spot (approx 2.5% or less of the area), the light meter will narrow the area it takes into account when metering and possibly use different algorithms to read the reflected light. No matter the size of the area being metered, if the subject and/or its surroundings are bouncing back wildly unbalanced light through the lens, your exposure will most likely not be calculated correctly.

Spot Meter Off of Middle Gray Tones

It’s helpful to understand how best to override the light meter when it is handicapped by confusing incoming data. A well known strategy: Try spot metering off middle gray tones that you know won’t confuse the meter (like grass down by your feet) and then set exposure based on those readings. If your camera is set to  Manual (M) Mode, set exposure parameters and then recompose, making sure that Auto ISO is not engaged. If you prefer to use one of the auto modes (Av, Tv, P, A), have the camera take the exposure readings of the grass by your feet, lock down exposure settings using auto exposure lock and then recompose the scene.

If the photographer is not quite happy with the results of these fixes, she can fine tune with Automatic Exposure Compensation (AEC–Right is Bright) to help balance the light meter reading. If you know your light and use the histogram as your guide, you can probably make an educated guess and get it right. (NOTE: Sometimes knowing your light is not enough – you must know your camera. AEC tends to be variable – depending on the DSLR in use.)

Know Your Light

After years of being a photographer, I like to think I know my light without the help of an in-camera light meter. Still, I rely on the meter all the time. It helps to understand  how this highly complex meter system thinks and how to work with it to produce images that are exposed to your liking.

Photographing a Red Breasted Nuthatch

I search out Red Breasted Nuthatches when I’m birding. Tiny, gregarious, and bold birds, they seem to always pause, like they are formulating a plan before they rush off. Gives me that moment I need to get a focus fix. Last summer, we had a pair that stayed in our yard to nest. So far this Spring, we have spotted two of these nuthatches. Sadly, they seem to be only passing through.

Collecting Perches

I often venture out into the woods to collect moss and lichen coated pieces of deadwood, drag them back to our property, prop them up near the library windows and hope the birds will use them as a perch. It’s not hard to strategically arrange these perches against the forest of trees that surround our yard.  Sometimes, I have to twist and turn the camera and tripod (left, right, up, down) to build the perfect vantage point from which to shoot.

This photo shoot took place in early evening under a cloud covered sky. Ambient light provided some illumination to the perch, but very little into the woods beyond. (As the season progresses and the trees fill with leaves, less and less sun penetrates these woods.)

As I was lugging this burly piece of deadwood, it occurred to me that it was oversized for most of the birds in the yard- and might cause the perching bird image to appear unbalanced in the frame.  I used it anyway because I liked its character…. the texture, color, shape, peeling sides, notches and curves. Plus its very heftiness would give it some stability in the wind.

Movement Caused By the Wind

Birds don’t seem to mind the swinging copper, aluminum, bamboo and wood chimes in our yard that resonate with the wind. This music portends that the camera will likely record swirling background patterns caused by movement within the distant woods and perhaps even little blotches of white and pink from the airborne blossom petals. This evening, I would just have to hope for a spot of calm when a bird alighted on my new perch.

Methods and Observations

  • While a cluttered natural environment does give a sense of place, it also tends to distract the viewer from the bird and its perch. I was aiming for less distraction…a plain darkish background, no swirls or fancy colors, no playful bokeh, no indication of the twigs and branches protruding out.
  • The subtleties of lighting (i.e. shadows and details) on your subject are much more apparent against a plain, dark background. For this shoot, I set the flashgun to Manual “M” so I could more efficiently control the light intensity and properly expose the subject but not the background. The most efficient way to darken an image background is by experimenting with the factors that you can control: 1) Flash intensity….The stronger the flash blast, the more likely the light will travel past the subject. 2) Subject and background distance….the wider the distance between the subject and the flash the farther light will have to travel;  and 3) Aperture setting….if the camera is set to a tight aperture, the light will fall off more quickly. It’s a balancing act.
  • Since birds are often tiny and distant, they don’t come within the normal range of a flash. For most of my birding adventures, I attach a fresnel flash extender on the flashgun to create more of a spotlight effect. NOTE: Without the extender, the light blast will spread wide, bounce and scatter depending on what’s in its path and the proximity of the subject.
  • The ambient light illuminated the perch as much as 2 stops more than the wooded background. I used the DOF button to see how much darker the background would appear compared to the subject. The more I tightened the aperture, the less the ambient light creeped in. I then played with the flash intensity, trying to control background exposure…. figuring out how much ambient light to record to produce a brown background.
  • My 500mm lens naturally creates a separation between the subject and its background. The longer the focal length, the more the angle of view is diminished.
  • I set the camera to partial metering, so exposure settings would not take into account the darker background.
  • After taking dozens of photos of a barren perch trying to get the light right, I sat back to wait for a bird to complete the picture. It did not take long for this Red Breasted Nuthatch to give me an opportunity to test out the exposure.

A Compelling Moment

Mixing up the exposure parameters in order to capture a compelling moment takes time. Doing this in-camera – not in post processing – is more desirable and rewarding.

Photographing Purple Finches – Thoughts About Focus Points and DOF

Thank you for sharing....Digg thisShare on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInShare on StumbleUponPin on PinterestEmail this to someoneShare on Tumblr

Photographing An Eastern Purple Finch

Purple Finches are irregular visitors in SW Michigan. We hear them singing high in the trees (gushing and emphatic) and love to watch them as they cluster in with the other finches at the feeders. When they do come, they stay only a few days.

In the Spring, the raspberry feathers draping the male Purple Finches glimmer in the sun. (This fresh breeding plumage makes it easier to tell Purple Finches apart from the more numerous and year-round House Finches). The females and immature birds sport crisp brown and white facial marks, not unlike the patterns on the female Rose Breasted Grosbeaks, who come to nest in our yard in early May.

Focus Point Sensors

For unpredictable and highly active birds like Purple Finches, engaging the camera’s army of focus points (primary/secondary and cross type) to quickly acquire sharp focus is a good idea. (NOTE: This assumes that you’d rather use the camera’s multiple focus points rather than frantically chasing the bird around the frame with one central point.) The complex array of focus point sensors connects, communicates and exchanges data with other systems in the camera to weave together an almost immediate, very precise and user directed autofocus.

It’s Not Magic

This process seems magical to me…so it is not surprising when I make assumptions about the capabilities and connectivity of the focus system that are just wrong.

What I know about the auto focus process on modern dSLR cameras:

  • Canon’s Al Servo focus mode puts the lens on high alert for movement. Designed to work hand-in-hand with whatever focus points are activated, it efficiently adjusts and readjusts focus the second it senses motion.
  • Empowering a mass of auto focus points without specific instructions can cause problems. It is advisable to pair the engaged focus points with an intelligent tracking mode that predicts movement and direction (mathematically); and then configure the behaviors that tracking mode should follow.
  • Judiciously choosing a selection of auto focus points helps the camera decipher what it sees. It takes practice (under pressure) to merge focus points into groupings with the rocker switch .
  • Maximum aperture on a lens is integral to focus – the more light it lets in, the more responsive the focus sensors.
  • Restricting the light metering mode narrows focus point activity.
  • Engaging your camera’s extra sensitive cross-type auto focus point sensors, (within zones or not) allows autofocus to read across vertically and horizontally placed lines for more precise focusing.
  • This highly configurable mass of focus points automatically re-orient (vertically or horizontally) if the camera is rotated- assuming you’ve set this function in the menu.
  • Focus point tracking sucks up battery power.
  • Even with all this user preparation combined with the camera’s complex and predictive algorithms governing movement and focus, ultimately only one little soldier point will be called upon to make the focus call.

Do Autofocus Points Work With DOF?

I had assumed that depth of field calculations would be included in all the focus point sensor math.  After all, locking down accurate focus is the goal and the camera and lens are interacting in a very sophisticated way. But that assumption is not logical.

Through the viewfinder, the photographer sees an assortment of things at a variety of distances. No matter how many AF points light up, the camera will follow specifications set up in the menu and do the math on the distances to ultimately select one point upon which to lock focus -most likely the closest object.  This one chosen distance is the point upon which the lens must physically position itself to focus. The specific aperture that you (or the camera) select makes no difference to the auto focusing calculation process….even though it will most certainly affect your range of focus….ie, how much your subject (in front of and in back of the chosen focus point) will be in focus.

Question Your Assumptions

So why did I think that depth of field would be integral to the complicated algorithms made by the auto focus system? Just because connecting the two can lead to more completely focused subjects doesn’t mean the camera is going to automatically do that for you.

I think it’s important to question the attitudes, beliefs and assumptions that a photographer brings to the art and science of bird photography. It’s a clarifying exercise well worth the effort.

Photographing a Northern Mockingbird -Canon’s Quick Control (Q) Button

Photographing a Northern Mockingbird

We were just getting going on our birding adventure when a Northern Mockingbird flew by and settled on a nearby camera level tree branch. I was excited that he was so close, not only because it is so much more gratifying to be physically close to a bird I’m photographing, but also because I did not have my longest telephoto lens with me.

This bird is not a common sight in SW Michigan, though the e-bird maps show them as prevalent and nesting in this region. Northern Mockingbirds remind me of another acoustically gifted mimic…the Brown Thrasher.

Branch Shadows Everywhere

I set up the tripod and camera, keeping my back to the mid-morning sun. The Mockingbird was constantly flitting about, so I set the shutter to 1/2000….. never mind (for now) the auto ISO shooting up to 2000. I kept a tight aperture (F/9) to increase my DOF as much as possible and keep his slanted body sharply in focus. The angle of sun light was rising fast…long past the time I could expect a complementary soft glow on my subject.

The bird’s face and body were lashed with unappealing shadows that had crisp high contrast edges from the branches and twigs on the trees. No natural reflectors were evident and the dark ground and tree branch perch were certainly not going to bounce light upward to the bird’s undersides.

My options were few:

  • Wait for the bird to move to a more evenly lit location.
  • Have my assistant (?) string up a large diffuser in the trees and hope the bird stays put.
  • Move the tripod to a place that would not create such unsightly shadows.
  • Shoot toward the sun..and try for a halo effect, being sure to spot meter the bird so exposure would not take into account the bright background.

For most of this shoot, the bird and I were constantly on the move. After a while he hopped to less shadowy places, giving me the opportunity to photograph him in better light. The resulting images still show patches of uneven, blotchy light, especially in the background.

Quick Control Button

Once in a while during a shoot, I like to get out of my comfort zone. If the bird gives me more than a minute to photograph her, I relax and luxuriate in the added moments I have to be adventurous and test my photographic skills and knowledge. (An intellectual challenge…given the light and circumstances of the scene.)

In this instance, I used the Quick Control “Q” short cut to functionality located on the back of the camera. Without this convenient panel, I would have to stop and dig through multiple menus to make adjustments. This Quick Control button, allows me to quickly review the image settings currently applied and adjust (using the cross keys) whatever I please….. image size, quality, metering mode, drive mode, exposure settings, FEC, EC, picture styles, white balance, AF operation, etc.

NOTE: The Q panel is highly configurable allowing you to place those functions you use most- or want to experiment with- on the back Q panel and at your fingertips.

Experimentation

It’s stimulating to dabble in uncertainty and respond with agility- even if the result is a failure. Given time and opportunity, it’s fun to abandon the comfort and security of what you usually do and be adventurous. If it comes to nothing, it’s still a worthy intellectual exercise sure to come in handy sometime in the future.
