I've come to realize that I simply do not like to take vertical pictures. When viewing the work of others it is not nearly as much of an issue, but in my own work I no longer take vertical pictures because they just don't seem to work for me. I don't know if this is because I really don't like them or I'm simply no good at taking them (and should make a point to practice). And I wonder, is there something inherently more natural to our eyes in the horizontal image? Or is it simply a matter of framing or content or purpose? This question may be related to one's preference for image proportion - 3:2, 4:3, etc. To me, 3:2 is the wonkiest vertical format. What do you think and what are your preferences?
