Going Macro With A Big Lens

Don’t get me wrong – I love my big lens. My primary lens for bird photography is the Canon 800mm, which serves as a real workhorse. However, there are times while using that lens that I get frustrated. One of the lens’ limiting factors is its minimum focus distance. I can’t bring any subject closer than 16 feet into focus, which means that very small things (for example, hummingbirds) still appear fairly small in frame. What to do about this limitation? Enter the extension tube!

Recently I took an out of town colleague to some of my favorite local bird sites. We found an area rife with anna’s hummingbirds, zipping this way and that, and generally causing a ruckus as they battled each other over territory. I took some shots, but couldn’t get close enough to these little creatures to fill the frame. I resolved to come back the following day, this time armed with my full array of extension tubes.

Luckily the hummingbirds were still there, sparring and resting, and this time in beautiful light. I wanted to get as close as possible, so I stacked three tubes together and placed them in between my camera body and lens. This allowed me to get as close as about 10-12 feet away from the birds, finally filling my frame. Creeping closer yet, I wanted to push my extension tubes to their limit, and was able to get the image below.

Extension tubes have no optics in them, and can even be in the form of cardboard – no electronics required! My tubes happen to have small contacts that still allow me to use my lens’ autofocus system, albeit much slower than normal.

The principal of an extension tube is to move the rear focusing element of the lens further away from the focal point, which in today’s world means the camera’s digital sensor. The effect is that the lens’ minimum focus distance is reduced, allowing the entire rig to move closer to the subject while keeping it in focus. The downside is that with extension tubes attached, the lens will no longer be able to focus to infinity.

In comparison to most photography gear, extension tubes are relatively cheap. I have a set of Kenko tubes that stack together. If you ever want to dabble in macro photography, I recommend first getting a (cheap) set to tubes before spending bigger bucks on dedicated macro lens. Yes, the macro lens will give you better quality, but a set of extension tubes will allow you to bring your entire collection of lenses into the macro world.

A Change Of Scenery Revisited

Years ago, I wrote about how long lenses give the photographer the ability to completely change the background of the image they’re working on while still behind the camera. With a slight move left, right, up or down, you can change the angle of your shot, and sometimes change the background elements that appear behind your subject. Because long lenses help blur the background into solid colors, this can change the look and mood of your photo without changing the main subject.

I’m always looking for these opportunities while photographing wildlife. Photo editors constantly seek variety, so when I’m on a bird, I try to get as many poses, expressions, and backgrounds as possible. I think of it like an outdoor “studio” session, giving me the ability to come up with scene changes for my subject. (I still haven’t figured out how to do wardrobe changes, but that is a topic for another post!)

In the photos below, I first photographed the greater yellowlegs with the shoreline of a lake as the background. The background blurred to a nice tan-brown. I then changed my angle by swinging around to the left, and now the lake was behind the bird, coloring the background in a blue wash.

You can achieve similar color changes using reflection (and patience) as well. In the photos below, I didn’t change my position, but just waited for the bird to move instead. When I first photographed this pied-billed grebe, it was fishing and diving close to shore. The colors of the shoreline were reflected in the surface of the water, contributing dominant oranges to the photograph. I knew that this bird was likely to move away from the shore eventually, so I sat a waiting, hoping to capture that color variety. I didn’t have to wait long before this happened, with an added bonus of the grebe moving closer to me, filling my frame. The blue sky reflected off the water, giving the photo an entirely different look.

The next time you’re out photographing with a longer lens (depending on your subject, anything over 100mm can work well), think about trying different backgrounds with your subject. This works great on people pictures as well!

Conquering My White Whale

After almost 15 fruitless attempts, I have finally photographed a local American Bittern that has been causing me grief. Time after time, I have gone to “the spot” without a trace of this bird, and time after time countless birders have reported seeing it, sometimes only an hour before or after my attempt. But I am happy to say that this ghost bird does indeed exist!

While not a rare species by any means, the bittern tends to be a secretive bird, often staying hidden within tall grasses and reeds. A few months ago, local birders began reporting seeing a bittern at Shoreline park in Mountain View, CA. I was excited about this opportunity, as I had never seen a bittern before and this location is relatively close to home. I soon found myself obsessed with finding this bird, half convinced that it would watch me approach in then dive into the bushes just to spite me.

Finally, yesterday, I succeeded in finding it after all those tries. I’m sure it felt more satisfying due to the difficulty – if I had found it the first time, I probably wouldn’t have been nearly as excited!

Monterey Bay Aquarium – Sandy Shore Exhibit

My favorite exhibit at the Monterey Bay Aquarium is the Sandy Shore Exhibit, a constructed habitat for a variety of local shorebirds, which for one reason or another have become captive and can no longer survive in the wild.

Here is a sanderling, which can be found up and down California’s coast. While they can be seen regularly roosting on the beach, it was great to be able to get up close and really appreciate each bird’s attributes.

I spoke to a docent at the exhibit, who said that many of these birds had been injured in the wild, and can not be rehabilitated to the point that they can be released. Others were born in captivity at zoos and other facilities, and made their way to the aquarium due to its excellent reputation.

These birds receive excellent care, being given food, shelter, and even extra attention for their young. The birds were quite comfortable with the visitors moving through their habitat, and proceeded with their natural behavior. With no glass or obstruction between the viewer and the habitat, you were able to feel as if you were amongst the birds instead of just viewing them from a different environment.

In addition to the dunlin and ruddy turnstone above, which are regular San Francisco bay area residents, a black-bellied plover was present in its winter colors. This plover is one of those difficult species to identify that can look like a completely different bird in the summer verses the winter. As I have been learning to ID birds, I find myself needing to learn not only each species, but each plumage a species can display throughout the year.

I was able to get excellent views of a semipalmated plover, which I’ve had bad luck with in the wild. The few times I’ve seen one have been at such a distance as to make it not possible to photograph. While photographing captive birds doesn’t really “count” per se, I still enjoyed the opportunity to see one up close.

I would highly recommend a visit to the aquarium, particularly this exhibit. Captive animals can serve as a great means by which to practice photography, especially if you do not have long lenses in your arsenal. Most of the shots here were taken between 200 and 300mm, all hand held. I’ll be sure to get back there soon.
