I prefer lightly lit photos because my complexion is awful I developed cystic acne as an adult, and it was bad to the point that 3 different dermatologists said they couldn't do anything more for me, after I'd gone through 7 prescriptions in a 3 year period. While it's toned down a lot, it has left me very insecure about my face- I won't even stand to be stared at, or looked at from below, I hate it...so my favorite pics are usually brighter, or B+W, or shoot, even the out of focus ones usually look better
Bit off topic here, but have you tried any of the dark spot correctors? I had cystic acne for about 8-10 years and after it cleared up I grabbed the Garnier Clinical Dark Spot Corrector and it cleared up a LOT of my scarring in about 4 months, using it twice a day. I had been on Differin, Benzaclin, and Triaz for years to clear it up and reduce the scarring associated with it, but they didn't really clear it up and didn't do anything for the scarring.
