How do you choose which, how much, in what order, in what size of the photos to show, in what layout, what web service, online or book or gallery, in photoset or singles, framed, random? themed? consistent?, text-descripted? blah blah blah
For the same photos of a photographer, all of these variables are tremendously affecting how people look at, judge, spend time, and value his/her photos. A great photographer will fail if he doesn’t know it. And am average photographer can be perceived much better than he/she is, if he know how these works.
