This is one of those goofy things I think about, and I'm wondering how you shoot...
Do you look through the eyepiece with your right or left eye? And do you keep your other eye open?
I saw someone shooting yesterday with a nice new 7D. She was shooting portrait, looking through the viewfinder with her left eye, kept her right eye open, and had live view on. SO her right eye was looking right at a screen less than 1/4 inch from her eye, which almost gave ME a headache. But it made me wonder, why is she doing that? As I said, it is goofy, but I have not been able to stop thinking about it, so now I must ask... How do you shoot and why?
