I'm taking a carbon printing workshop in a couple of weeks and have been going through my negs looking for ones with really long tonal ranges.
Something I've noticed looking at carbon prints by others, is that they all seem to be landscapes. I can't remember ever seeing a portrait done with carbon. Is there a reason for this? Is carbon unflattering to skin tones? Does carbon appeal particularly strongly to introverted, go-off-into-the-woods-by-myself types?
