What type of camera are you using? Truthfully, I don't even try and take full tank shots because it is so difficult for me. I'm not a big photography person but if you post some information about your camera and the settings you are using there may be others here who can help.
I for one would still like to see a tank thread. Perhaps I'm just a sucker for them.
It's a Panasonic digital camera model DMC-FZ8, I just got it a few days ago. If someone would show me some simple, basic setup to take decent pictures, I might try to do a tank thread. I've been reading up on photography because I know nothing prior to buying this camera.
:hammer: Be like me, buy a nice camera, dont read the directions, then be mad about how crappy your pictures are! (still havent read directions!) I think its a man rule. And I will not break a man rule! (unless significant other says so)
