A friend of mine is looking to have a head shot done for her business card she said she wants a black background which is no problem but she also said she wants to wear a black top... I told her she might come out looking like a floating head so she said she'd bring a lighter top also just in case. How can I make her stick out from the background... I have 2 off camera flashes.. should i just put 1 behind her for rim light?? Should i point the flash at the background? Or am i being silly and if the flash and exposure are correct it will light her black top?
