GUI Improvement idea: exposure control
I think that if you can overexpose some pictures it will be easier to identify what kind of animal is there (in some cases):
In some cases you can find that a dark picture is hidding some animals and "nothing here" can become "a pack of wildebeest". I don't know if the problem is with the bright control of my monitor, but...
(sorry for the bad english, hope you understand).
This is the same image with brightness, contrast and hue saturation turned up.
