Photos of hands for machine vision

I'm currently building a dataset of hand images to train a computer vision tool and looking for people to send me 4 pictures of their hands (right hand thumb, right hand fingers, left hand thumb, left hand fingers)

Photos are to be taken with a smartphone camera, parallel to the hand approximately 10-15cm away

The hand should be firmly placed on a flat surface

Photos are to be taken with standard-sized card similar to the attached ones (could be a credit card or any other card that's the same size as a credit card)

Please make sure the edges of your card show (so we can size properly)

Please try to keep your fingers straight - (no twisting) so that the entire nail in each finger is visible

Please respond with a suitable price per set of 4 images
