Q1: A big problem for me is that my body tends to incline back and forth in a small range when I ready to trigger the shutter. Of course I put my feet apart in the width of my shoulder as anyone suggested, but what's the better for you, put legs one left one right or put them one front and one back? Q2: If I keep the whole upper arm and elbow stick my body, I always find it's a little lower than my eyes for most subjects ... Should I lower my head ? bend my back? or keeep my back straight and bend the legs? Any suggestion and ideals is welcome.
