I was surfing the Scheinder [aka B&W] website awhile back and noticed a comment about using those graduated colour filters with B&W film. Anybody try it? It would seem a nice idea. Use a red or orange filter to get the sky right without darkening everything else. The filters are designed for colour use so I guess I'll need to look at what light they pass but any other issues people can see?
I know B&W is in the business of selling filters so I naturally assume they're too positive on the process-)
