You cannot use any filters of any kind on your photo. Part of the challenge is to take your picture in such a way as to recreate as exactly as possible. So, if you can use lighting effects to achieve a "black and white" look in your photo, that's great. But altering the photo with a filter to make it black and white is not allowed. Thank you for asking for clarification. Happy Hunting!For the poster thing, can I make my photo black and white? The one I think of using is in a black and white/sepia look to it.
