Changing color of subject – arm giving blood
I am doing a project where my arm was shot while having some blood drawn. The object was to show only the needle and blood vial and not my arm. The person we are doing this for is much lighter than I. I told them I would do this only once! Now, I need to know if I can change the color of the arm without affecting the other objects in the shot, mainly the blood going into the vial.
Thanks for your help.
