This week, a couple books about Saul Leiter show that great photography is not always about per pixel sharpness and bright, saturate color. The problem is, when do you know when it is and when it isn’t? Can a photographic style be plotted like a course on a map, or does it only happen in the rear view mirror? Also, video seems to be the “it” factor for much of the photography industry, but is it worth it, when you consider the gear, the time and the ability required to really do it well? Arthur Tress is our Photographer of the Week.
