At my hand modeling casting it isn't just my hand I am paying attention to- It is my whole body. I have to hold a beer as if I am passing it to a friend at the bar.
That is all I am told.
So I pick up the beer. So I imagine my boyfriend as I reach out with a smile on my face, I make sure the label of the beer is facing the camera and even though my face is not in this shot, and this casting is only for my hands...I smile.
By smiling and pretending to be in the moment of passing my boyfriend a beer, my hand relaxes, looks natural and hopefully comes across the way the photographer and art director picture the ad, and I get booked!
