armtuk: Cheetah (photography bird)
Today is Saturday, which means I get to go out during the day and take pictures anywhere I want, well, within reason (Phipps conservatory in Pittsburgh is on my list, but that's a weekend, not a lunch-time jaunt). Based on reading I did, I decided to mount the 100-400mm directly on my camera without the extender, which is supposed to improve picture quality, and also means I get auto-focus back.

It was a good call. Today's pictures I think turned out better than almost anything else I've taken. I noticed right away looking through the lens that colours seemed brighter and the picture seemed very sharp. On these pictures, I hardly did any colour modification at all in Aperture. All I really did was crop, and occasionally sharpen.

Today I went to Marsh Creek with my new lens. The birds were very far away, that even with 800mm effective focal length, I was stumped for a good picture. Add to that that the lens I have 100-400mm does not use auto-focus with an XSi body if an extender is connected and we have a recipe for crapness.

So I took some pictures of rocks, and a tree, and some water to at least try out the new getup. They were mostly at f11 at 400mm balanced on a Canon monopod with a cool swivel head.

Then I came home, and took some pictures of our kitten Rothko as we haven't had new pictures of him for a bit. Then a bug landed on my desk, and I coaxed it onto a white-ish box and took some macro pictures of it. Those pictures were done with a 100mm f2.8 macro lens on a 25mm extension tube. I wish I could have made the depth of field bigger, but one 300W light at F4.0 at 100mm plus extension tube == slow exposure time / large magnification. You can see the faint traces of camera shake creeping into the pictures.
