Anyone film themselves shooting? Periodically I do. It is a tremendous aid and I would recommend the practice to anyone who has yet to achieve perfection in their shooting.
+1. It is particularly useful to discover creeping, head movement, and alignment issues. In other words, things one has done wrong for so long that they feel right.
I had a golf pro who gave me a lot of lessons over the years. He never used a camera rather corrected things in my swing and they would feel a certain way to me after his corrections. By repetition muscle memory would take over and guide me.
However if you don't have the benefit of a coach standing there and correcting your each and every fault I would say a camera would be the second best help.
I could never correct my own swing by looking at videos or picture though.
Lets just say I have plenty of blatant corrections.
I film myself frequently to examine my release and form. I find it really helps reinforce good form habits.
I film myself all the time now that I have an iPhone it's very helpful and I've corrected a few mistakes because of it. Everyone should do it
