Re: Painting from progressively less blurry image ?
Resurrecting a little bit old thread, but I wanted to add another "tool" to this:
Posterize. If you struggle with recognizing value changes (especially across organic objects), Posterize separates the smooth value gradients across a face for example, into bands of value. Useful for me for the early stages of laying down value. Only to use as a starting point though, because if you stick to firmly to the placement of the values, it will make the lighting unnatural.
