Judging the Snap

Hi,

How to judge a snap whether it is good or bad after taking it using a DSLR 350D?

On what factors we brand a snap whether it is good, better or bad?

Basically i immediately look at the histogram in the info and come to a conclusion that the picture is good or bad or poor light or the light is not sufficient.

I need to know how to judge the snap whether it is good or bad?

Also i would like to know how do we judge whether this photo is ok for printing or not?

Regards

There's no question that some images are noticeably better than others due to the lighting at a particular time of day , lens used, etc but when you manage to get familiar with your camera/lens output under varying conditions you almost know what to expect.

Assuming you weren't shooting in A mode and you know the ISO,shutter speed, aperture,and focal length just checking the histo after the shot is about all you can do to short of posting it on a computer screen for further evaluation.
