You wanna hear something funny? One of the most difficult aspects of photography is hand placement. There are all sorts of unwritten rules to consider: show the backs of male hands and side of female hands, don’t let the hands become a distraction, don’t crop at the joints, etc.. Not only that, people have no idea what to do with their hands once you draw attention to them. I’ve had models and clients alike remark to me “You know, this modeling thing is hard!” It takes great skill to purposely position hands yet have it still look natural. Sometimes that has to come from the photographer and sometimes the subject just knows how to do it gracefully.
It doesn’t seem like it would be that way since we all use our hands daily. Yet there we struggle during the session trying to figure out why our hands don’t look natural in certain poses. To add even more difficulty to hand placement, everyone’s hands are different. What looks graceful and delicate on one person can look forced and unnatural on another. Some hands are athletic or utilitarian, others are petite.
Sometimes, quite rarely, you get someone whose hands are just naturally delicate and no matter what you ask them to do, they just look great.
