just ask the woman you're interested in seeing. some do and some dont. i have seen about 5 or 6 women over the years who've let me photograph them and me [not videos]. just be respectful about it.
i believe brazil suicide girl allows photo cameras and video cameras for an extra fee.
Just remember, if you use your digital camera and you later erase your CF card to get rid of the evidence - those images are STILL on there. I used a recovery program one time to get some business photos I accidentally deleted - and was quite surprised to see what ELSE was still on there.
