New to image analysis

This is new to me and I am not sure this program can do what I want.
We use disclosing agent on teeth then take a picture of the teeth.
I would like to analyze how much of the tooth is covered and covered at what intensity, which tends to get less intense the further from the gum line you look.
Will this program allow me accomplish this?

Welcome iceruam,
Yes it can, although it would be better if a reference image were included so we may better aid you.
