iPad sketching app or switch off touch screen
I'm essentially looking for an app that will turn my iPad into a light table so i can put a piece of paper over the top and sketch the image underneath. A general way to disable the touch screen would work so I could sketch straight from a photo in the gallery but i don't think that is possible. Yes I am aware of the potential for damage so please no replies about that, it's first gen and probably time for a new model soon. If this sort of function is not available in any way then an app where I can digitally sketch over and image and just save what I have done myself and not the base picture would also be fantastic. This seems like a fairly simple ask but i can't find a straight up simple answer anywhere.
