So, how do people cross their arms? Which arm is nearer your body and which is on the outside?
I have my right arm nearer my body, it's the only way which feels comfortable. My sister told me last night that my back was twisted and my left side is higher than my right so maybe that has something to do with it.
I'm left handed, and I use either eye depending on which is more convenient at the moment (and hold the camera in either hand as well.) My left eye is stronger than my right eye (according to my eyeglasses prescription) so I tend to use it more, but since cameras are made for right handed people I sometimes use my right eye as well.
