Grndzer,

Since we can't see ourselves shoot, other than by filming with a video camera it is difficult to detect or know your form flaws. This is especially true if bad habits have been formed because everything feels comfortable to us. An experienced coach that is trained to teach correct form will be able to instruct you in what changes need to be made. There are other important things that can be instructed like backtension, pacing of the shot sequence.

Aim Hard!
