Well I know what I'm doing (partly) as far as settings go but it does take some practice. Each set of pics I take definitely continues to look better but since it is my first digital SLR I know I've got a long way to go. I know the last clown pic is horrible but it was such a nice 'pose' I decided to put it up anyways. I also did use the timer on all my shots (except fish ones) because otherwise its so blurry you have no idea what I am taking a picture of.
I was going to get the d80 but really wanted the 18-200 lens which was on like a 6 month waiting list, but it did come packaged with the d200... so I went above my skill level on this purchase by a lot. I do feel I got pretty good images with the pink zoas, the angel, and I also like the blue blasto. The rest all definintely show room for a ton of improvement.
Thanks for all the comments and suggestions, any more? I really do appreciate any and all feedback (even if you think I stink, cause I can't learn without criticism). Any other d200 users out there that have some suggestions they just couldn't take tank pics without? Or other suggestions overall? I have found it is MUCH harder to tank tank pictures than in other settings. I went outside and took pictures of flowers, etc and it was so much easier with natural sunlight (especially on an overcast day).
