It is possible, but it sounds a little strange. It would seem to refer to the practical process of developing and printing. Now that photographs are more often printed using inkjet or laser printing processes, there is no real technical skill involved. It is also "faint praise". The photograph is well printed, framed etc...(but lacks creativity)
So "workmanship" does not seem to be the correct word to use. "Skill" is a much better word. It also avoids the gendered language of "workmanship" You might also add "creativity", "artitry" since this is important for photography. You can talk about "technique", perhaps "finesse" or "expertise".
You can, if you wish, talk about the "technical qualities" in contrast to the "creative qualities" of the photograph.
If you want to talk about the photographer you might highlight his "professionalism"
