Jason really enjoyed the Sea Life Aquarium at Legoland. Of course, I still prefer the Monterey Bay Aquarium, but the one at Legoland does have in its favor the fact that it's explicitly directed at children, and so there are a lot of fun interactive demos and shows.
In this exhibit there were actually three or four different species of clownfish. As soon as he saw it, Jason ran over, yellow "Nemo! Nemo!" His memory has really been impressing me lately--the last time he saw Finding Nemo was when we visited my mom and stepdad six months ago.
Technical info: Shot with a Nikon D40 and Nikkor 35mm f/1.8 DX lens, in manual exposure mode. Aperture f/1.8, shutter 1/125 sec, ISO 1600. Post-processing in Aperture 3: curve to add contrast and increase midtones and highlights, brushed in over everything to the right of the rock; burned the background behind the fish.
Thoughts for improvement: The focus is a little soft, and, of course, the D40 doesn't do so well at ISO 1600 in terms of noise. Probably it would be better, too, if I had placed the fish off center in the frame.
