B&W Viewing Filter
I spoke about this viewing filter in my The Creative Edge Live webcast of "The Art of Seeing B&W" Everyone was so excited by this I wanted to offer you this exclusive opportunity to grt one of your own!
You hold this filter in front of your eye to view the scene you are considering photographing in black and white. It makes the scene monochrome to help you better visualize a black and white image.
DO NOT SHOOT THROUGH THIS FILTER. IT IS ONLY TO VIEW THROUGH!
