I know this is probably a "dumb question", but how do you go about making the background of an image completely pitch black? How do you make it so no light touches behind the subject? This just completely stumps me. I hope this doesn't involve any black walls. For example: http://www.flickr.com/photos/toma01/2697834739/ this photo. (i can't copy it, supposedly) http://www.flickr.com/photos/bangyougotme/2794576767/ Another fine example I'm really into dark lighting photography. Knowing how to pull this off would be an extreme joy to me. Also, another problem. When my Nikon D80 is around 1/250 shutter with off camera flash, my camera only picks up about 3/4th's of the photo. The other 1/4th is completely black as if something was in front of the lens. It's really weird, and when I point it out the window, it works fine.
