i try to find the closest matching color to patients tooth and it works by
using Versatile Wand. but I have some problem with quality:

1)when i open RAW/NEF photo it is a very small 75k image, originally it is
42mb. when i import it, i've got black window. working on jpg file is
loosing quality i need.

2)should i work on rgb/Lab color mode?
