Long and short on teleconverters

When you're a wildlife photographer working in a public park, the equipment you use undoubtedly draws attention. This summer, I've been documenting the development of a pair of young bald eagles. To get the images I need without disturbing the birds, I've been using a 600mm lens – a 13-pound monster of a lens that has a front element only slightly smaller than a dinner plate.

A small number of people come up and ask me questions about the birds. Many, many more grill me about my equipment. The vast majority say something like, "I bet you can see every nose hair with that." I cannot. In terms of magnification, the lens falls in between a pair of binoculars and a birder's spotting scope. The lens is physically big because it lets a lot of light in allowing me to capture action images at high resolution.

It's the second most common question that I'm going to address in this blog post. It comes from amateur photographers who want to know about my use of a teleconverter with this lens.

Nesting season is for the birds

All birds lay eggs, but where they care for them and how their young develop can be remarkably different from species to species. This spring, I've been watching several families of birds.

Get close by keeping your distance

For the second year in a row, there are fairly large numbers of snowy owls that are wintering nearby. Near Seattle, snow geese are a regular winter feature, but snowy owls are a rare treat. Reckless photographers, though, are in danger of driving our infrequent visitors well back north — or even worse.

A waterfall of murres

I've seen plenty of waterfalls, but until recently, I had never seen a "waterfall of murres." That's how friends of mine in Cannon Beach, Oregon, describe a truly wondrous nature show that takes place this time of year on the nearby Chapman Point.

Don't let backyard photography give you cold feet

The black-capped chickadee is no ivory-billed woodpecker. Dozens visit my office window every day to feast on the free suet.

But just because they're common, doesn't mean they are not interesting. And a recent snow storm that, at times, had my yard buried under nearly 10 inches of snow allowed me to create some images that help tell their remarkable winter story.

Moving the camera to stop motion

The usual goal in photography is to create an exceptionally sharp image. If you're photographing a bird, for example, most photographers want an image that's so sharp you can see every feather on the bird and every barb on the feather.

To capture that, you typically need a sturdy tripod, a cable release, lots of light — and a stationary subject.

But what if the light is dim and your subject is moving? That's when you need to pan — moving the camera with your subject. It involves moving the camera so that your subject is always at the same spot in the image.

The story behind "Pair of Bald Eagles and Moon"

The lucky part was driving behind this bald tree and finding two bald eagles using it as a platform to hunt for food. The not so lucky part involved wading in a freshly-fertilized field to line up the tree with the rising moon.

On a first date, no less.
