It's perfectly okay. I've come to realize that I learn a lot by looking at other people's photos and telling myself what is good and what is bad about it. And honestly, this was one of the easiest shots to take. I mean, they're just swimming around in there; all you have to do is go up to the glass and click the shutter. This is one of those photos that wouldn't have been as good without some post-processing.
i really like jellyfish photos and i like this one too... But i think it woukd be more expressve if u had a single one that was moving or if you had taken more of them and there was some spaces in the left and rigth sides.
Hm... I'll go through my photos and see if i have one of a single jellyfish. I'm pretty much positive I do. There seems to be mixed feelings about the empty space on the right side. Some people don't like the "dead space" and some say it'd be too busy on if the space was filled up. I'm actually kinda indifferent.
Actually, awhile back ago I learned a really neat trick when dealing with glass. What I learned is that if you bring the lens right up to the glass, it won't pick up as much reflections. It makes sense, because it's photographing less of the glass, hence less reflection.
Other than colors, there's actually only a really small spot where I edited it. The majority of the editing on this is color. But uh... back to the question. I think it mainly had to do with the fact that the room was pretty dark. Also, I've learned that the best way to shoot something through glass is to get the front of the lens as close to the glass as humanly possible. The reflections can't get to it that way. And I did not use flash. I can post the original if you'd like.
