I am interested in the photoshaping process as a means of making shallow bas relief models to cast molds for jewelry. Questions I have are: Can the detail material be used? What is the depth distance in mm from 100% black to 100% white in this process? How many levels of gray are used? Does the photoshaping creator app have to be used or can a grayscale file be submitted? There is obviously a backing base of material...how thick is it and can that vary? Thanks for any comments or information you might have.
