I don't know why, but when I read your original post, it reminded me of Dr. Seuss... See the shrimp on a log.... I'm sure if I were poetically inclined, I could do something with that...
I used a Canon powershot A80. Iv'e got the macro and focus down, and am learning about shutter speed and aperature settings. What I could have used in two of those pics are knowledge on white balance settings.
Many thanks to Matt W for hosting that site. A great service to AC!
