Photographing Birds

Who can turn down an opportunity to photography a beautiful Cardinal, Oriole, Hawk, etc? At first, probably no one. But when the prints come in, or you see it on the screen, you may recall having thought “Where’s the Bird?”, kind of like this shot of a Cardinal in the photo below. It didn’t look like that when I shot it. (or did it?) There is a bird in there somewhere.

Don’t feel bad. You’re not alone. It’s interesting and sometimes frustrating to figure out what lens you need to photograph birds in the wild. It really is about the lens. Unless your name is Dr Dolittle, most of us can’t get the birds to come close, sit still, and pose for us. Of course there is always the alternative of hiding in a Blind and waiting for the birds to come to you, but that isn’t always possible. Here’s a great video example of this. I’ve always had an interest in photographing birds, and having had the common experience described above, I also realized soon after that I would need a good telephoto lens, and a teleconverter to extend the reach of that lens. The question was what focal length do I need?

On to mistake number two. Looking at your lens budget, and thinking that surely 200mm-300mm is a long lens, you make your next purchase and head back out to capture the ellusive bird. (that’s after spending anywhere from $180 to $5000 to get to this range, depending on the quality of the lens.

Once again, you get home to see the results, and now you have something that looks like a bird, (see below) so you’re thinking Ok, I’ve got it! You crop 80 percent of the photo to get to a photo that you hope looks like the front page of some Bird watcher magazine, or National Geographic.
Crop

You end up with what looks like an out of focus bird photo taken by a cellphone. Not exactly good news. One of the added problems of not being close enough is getting the autofocus system to lock on this tiny bird rather then the twigs in front of it, which is what happened here. Manual focus doesn’t help much when the subject is this small in the viewfinder. Now this is getting expensive!

Going through this myself early on got me wondering why my perception of what focal length I needed was so far off. Or was it some kind of optical illusion?

Optical Illusion or Perception

It feels like an optical illusion, but there is no real false reality here, so it must be a problem with size perception and a misunderstanding of the camera’s resolution. This got me thinking about the idea of size perspective. For example, if a person 6 feet tall is standing fifteen feet in front of me, and I zoom to 80mm, that subject is going to fill a good amount of the frame.

Now do the same with a tiny 4 inch bird at the same distance, and see how much of the frame is filled by the bird. By the way, the person is 18 times larger than the bird, and yet it’s hard to get much closer than 15 feet to birds. At the same 80mm focal length this bird is now filling a tiny portion of the viewfinder. Can you say Crop? As you crop you are losing resolution. So you crop out 80 percent of the image, and what do you have left? With a 12 megapixel original, you now have a 2.5 megapixel photo, and whatever it is, it doesn’t look like a magazine cover. Why did we think this would work? There isn’t enough resolution left to show any fine detail.

I think the answer probably lies in how the eyes and brain work together to filter out everything except the subject that we are focused on. At that moment we lose perception of size relative to our field of view. Possibly our eyes do better than 12mp at this distance, but I’m not sure. Either that or our eyes just have less focus problems with tiny moving subjects. That’s probably more likely.

The Solution

The photo at the top solves the problem in two ways. First, the lens is a Nikon 200-400mm zoom with a 1.4x teleconverter attached. The final focal length was 550mm. Keep in mind that even at 550mm this only worked with the bird at around 20 feet away. The ideal lens is a 600mm with a 1.4x or 1.7x teleconverter, which ends up getting you to 840mm/1020mm. Nikon’s version of this lens, at over ten thousand US dollars, is very cost prohibitive. There are other brand lenses though that can be considered with some trade-offs and a lower price. However, this is what keeps most camera owners away from birds that aren’t in a zoo or a feeder.

The second factor is the camera’s resolution, but this is less important than the lens. The Nikon D3X used at the top is a 24mp camera, so it has twice the total resolution of a 12mp camera, which means it can capture more detail in the same portion of the frame, which helps. However, it’s also a very expensive camera body in its class.

[Update: Some thought I was saying here that a 24mp camera is required to photograph birds. This is not the case. The point is that higher resolution helps when you are cropping. With the right lens 12mp is more than enough resolution. In fact, top notch photographs of birds have been done with far less than 12mp.]

There is also the crop factor of a digital SLR that has an impact on the density of pixels relative to the frame, but that’s another article.

Try this next time

Ask yourself the following when photographing anything that is very small:

- How much of the frame is my subject filling?
- What percentage of the frame will I need to crop because I couldn’t get close enough?

If the subject doesn’t fill 25 percent of the frame in one direction, it’s time for a longer lens. Or there’s always the possibility of a postage stamp contest. :^}

Let me know what you think by posting a short comment.

What is Fine Art?

As a Musician of many years who now concentrates on Photography, I can say that the same hang-ups over what to call ourselves and our work are present in both art forms. Lots of musicians don’t call themselves artists, but of course they are.

In the online photography community there is a serious hang-up over the term Professional, which I’ll not get into, because there is no right answer. Some define the term as someone that makes their living with Photography, and others use it as a term to indicate a level of experience.

I’m more interested in the term Fine Art, and this is even tougher to define. Right from the start, having -Fine- in the term causes problems, because of the qualitative connotations. After-all, it’s Fine Art, not pretty good Art. So it sounds like it’s all about how good it is, but that path is wrought with problems as the tendency will be to formularize every aspect of photography.

Which qualities are the ones I need in Photography to be able to call a print Fine Art? Sharpness, composition, perfect color palette, a certain depth of field, paper type, the mat or frame, etc. Maybe five hours of color correction in Photoshop will make it Fine Art. If we go down this road, when is enough enough?

Actually I don’t believe that Fine Art refers to some formula of perfect photographic mechanics. If you can stand a Jazz analogy – some tone purists criticized Miles Davis for the quality of his sound. It was airy at times. (Think noisy in terms of photography.) However, once you got over your hangup about his non-orchestral sound, you could start to see that the airy sound introduced an artistic element, or a unique quality that made Miles Davis something special. The air in his tone became part of his art.

He broke the so-called rules and made art.

Dictionary.com has this to say about Fine Art: a visual art considered to have been created primarily for aesthetic purposes and judged for its beauty and meaningfulness

That definition partially works for me, and I find the idea of Intent especially important. Beyond Intent, which I already have, my current and personal criteria for my own work:

1. It must have a spark of life. If the paper opened and the photo took a breath, I wouldn’t be surprised. Startled maybe :^}
2. It must have the highest quality presentation

Ok, so I introduced a personal rule of quality here, but of course there is nothing wrong with quality. What Fine Art is NOT is a list of rules defining quality in all aspects of photography. (as in noise-free, perfectly sharp, etc)

Alain Briot’s comments on this subject are insightful. I mentioned to him that his definition should really be in the dictionary. Not that everyone will agree, but even the dictionary shows multiple usages for words and terms.

For me a fine art photograph is one that is done with the goal of creating a work of art. It is an image that is done with a high level of craftmanship and care. It has to be mounted and matted to museum standards, in an archival manner.

Above all the cost should take a second seat to the concern for quality. Fine art is about quality, not about quantity. It is not about trying to save money by buying lower-priced inks, paper, matboard and other supplies. It is about creating the finest piece you can create, regardless of cost.

The goal is an artistic rendering of a subject in the finest manner possible.

Regardless of price and cost, a fine art print should sing. It should have a lyrical quality. It should transport you to a different place. It should open a window on another world, the world the artist is inviting the audience into.

This strikes a balance that I like, and puts the idea of Quality in the right perspective. Please leave your own comments on this subject.
