Photo Editing

The first step that every photographer makes is determining which photos to keep and which ones to get rid of.  HOW DO YOU DECIDE WHICH PHOTOS YOU WILL KEEP?  There is a reason you are deleting some photos while keeping and working with others.

Okay, here comes the answer, "those photos are good and the others were not so good".  Maybe this universal answer is formulated because people are just too cool to express their actual feelings, or, maybe it is because we as photographers have fallen into an area where we are losing sight of what constitutes strong imagery.  Before every single photographer that reads this throws a shit-fit, answer me this.  If photographers are not losing sight of 'composition' then why do the majority of comments on photo sharing sites say something like "nice shot" or "pretty picture"?
