Your photos can be made or broken by one thing. HANDS.
Hands have the power to make or break your photos.
Most people don't realize how important hands are in a photo. Hands can make a photo feel natural or incredibly stiff and forced, all by their position and what they look like.
Especially in group photos - be careful of the dreaded 'everyone-with-their-hands-down-by-their-sides' photo. Give people something to do with their hands, and it will immediately make your photos seem more natural, authentic, and personal.
