I know that I habitually shoot with the left eye to the finder, but I do this so automatically that I couldn't say exactly why. Is it habit alone, or brain function as I've sometimes heard, or is there some other reason that factors into this? So I got out the M6TTL and tried to see what it would feel like to use the other eye...maybe I could discover the reason for my left eye choice by doing this. As expected, it felt awkward, but by switching back and forth I think I found the reason for my choice: When I place my left eye by the finder, I press my nose against the camera. This gives the camera a three point, rather than two point, support. The three point support (left hand cradles lens, right hand holds right side of camera, with index finger on shutter release, back of camera pressed against nose) seems to allow a steadier hold. When I try right eyed shooting it feels like I'm depriving myself of a substantial steadiness advantage. Those of you who already shoot left eyed: Do you also press the camera against your nose for steadiness? Right eyed shooters: When you try the left eyed/ nose press posture: Do you feel any advantage in increased steadiness?
