Thanks for the replies & critiques guys!
First, thank you for telling me what you think, its going to help me.
I try to keep the shots parallel(ish) to the glass but since I'm shooting by hand and am (at times) following a fish I try to shoot with a high shutter speed so it won't blur the subject. I'm going back and forth between using live mode on my LCD screen and the eye piece but I'm having some issues with both, trying to get a good focus is somewhat difficult but I always use manual zoom so I am to blame if its out of focus. Maybe its my eyes but the eyepiece seems harder to me...I need to work on the focus adjustments more.
I just came home from Walmart and picked up a $15 targus 67" monopod. I am 6'4" so I figured this would be good for hiking in the woods and whatnot, I just measured my tanks and I am gonna get a tri-pod that will extend to near my needs, even though a cheap 50" tripod will work for my tanks, I think I'd be disappointed in the quality.
I will work on my settings, the FTS & paly shot was shot my first day and the cichlids & clown pic are fom the other day.
I will keep at it and try a tripod and other techniques and settings, along with taking more pictures (in RAW soon) and getting a better exposure & focus.
Thanks !
