Using photos--especially on a digital device--is a problem for me because photos tend to over-brighten the lights and lose the dark values in murk. That is, subtleties in skin tones and values are often completely lost for much of the image. For me, taking good quality reference shots is a considerable challenge. Some people use a computer to edit those things, but I'm not adept enough with photo-editing programs to do that.
Work remains to be done on the sweater and on the neck and chest, as well as final adjustments of skin color. Given the problems with photographs, all of these await a final life session.
