Being right handed I shoot with my right eye heheh if that is the right thing to say heh.... And it makes sense to me because less of my nose will be smudging on my preview screen in the back of my DSLR and I can get closer to the viewfinder heh. I remember in those days of SLRs....I alway have this oily spot in the back of the film back due to my oily sweaty nose rubbing on it
