Take a photograph of hand(s). Other objects can be present, but the main focus should be on the hand(s).
The hands can be doing something, showing emotion, helping, or giving a message of some kind.
For inspiration at the winner of the 'hands 4' contest 4 years ago:
Here you can see all the entries that were submitted:
Hands 4 Photography Contest on Pxleyes
Your photo can include any props you may wish, but the only part of the body visible should be the hands.
Be creative and let your hands speak through your photography.
Good luck!
