Ghazanfar Ghori. I wasn't trying to "police" your opinion, but you did take the time to post it and I thought I would take the time to read it, and give my 2 cents worth. Probably comes from the interest that I have towards composition. I apply it to everything in my life.
Now if the original shrimp was as red as yours, I could see what a great contrast the picture would be. By the way; that’s a great shot you took of your guy.
I have had several unsuccessful attempts at shooting my tanks. I was trying to use my Digital camera, but when you turn off the flash the camera wants to do a long exposure time, hence creating a blurry image. Which I don't understand since there is no film to expose.
I guess I will try and shoot some with my ol' Pentax..
