When i vote i look at all six images and see which ones grab my attention, if I've seenit before it drops the ranks. and the i look at how subject suitable they are. ie a fence post in a nature scene is an auto disqualification. Finally i look at the technical aspect, composition, pp, what lengths did the op go to in effort to capture the image. If it was all supposed to be based on technical merrits there would be categories "sharpness" "5d3" "L lenses" and "pixle peeping"
