I know that photographing darker skin tones was a problem with film, and I know the problem persisted with digital technology to some extent. I was mostly using my iPhone to photograph Brownie and Girl Guide events and I noticed that the girls with darker skin don't photograph as well. Mostly I was cleaning it up in PS with brushes. Today, I brought my DSLR to our Craft Day event. And... it wasn't much better. I was mostly using the "auto" setting on the DSLR, but the "indoor" setting was worse. If I used a flash, the lighter skinned girls were white as ghosts. Any advice on what I need to adjust for a group photo where I can see everyone's facial features?
