If it was up to me, in general I would probably only have two categories of photograph: 1)People...and...2) Everything else. Maybe I am just a "rebel without a clue", but trying to pigeonhole things defeats the object of art.
I take a "portrait" type photograph of my subject during a "boudoir" session and then tweak it in post production into something "artistic" and am then confused as to which box or album to put it into?
