A lot of creative photographers are left eye dominant e.g. Ansel Adams. The left eye connects to the right side of the brain, the creative side. Moose Peterson is a left eye shooter and I saw him demonstrate a shooting technique that has an additional advantage that I, a right eye shooter, am jealous of. A left eye shooter can stand a little sideways and tuck his/her camera & lens against their left shoulder for additional stability. A big plus when handholding at slow speeds and/or with longer lenses.
