This is a new process I am experimenting with. Setting up a subject on a lightbox, I photograph the heavily back-lit object. Using multiple shots in a bracketed sequence, I layer the shots together in Photoshop and then start to play... I heard someone say once "1/250th of a second to take the shot, 250 hours to process it". It's really easy to overdo it, but like I said, I'm playing! I'd love to hear your thoughts - e-mail me, or stop by my Facebook page and leave a comment!
