Well, it seems that at least part of my problem with my index finger was spending too much time on the computer. Or, that's why it wasn't going away. I spent most of yesterday baking, and very little of it on the computer, and guess what? It didn't bother me much yesterday, and I woke up with it mostly fine this morning. I'm going to take that as a win.
I may put some baked-goods photos up tomorrow or Monday. Possibly a few more, depending on what kinds of photos I take while I'm hiding behind my camera tomorrow. I already have better photos of animals than I've ever been able to take before, thanks to more and better manual settings on the Nikon D50 than my point-and-shoot camera has. I'm pretty excited, because I always want cat pictures to look at while I'm at school, but I only have a few that are any good (meaning, in focus and not blurry, not even necessarily good compositionally).
