So I often peruse the 'specialty films' section and I've always wondered about this film. http://www.bhphotovideo.com/c/produ...0100_Electron_Image_Film_SO_163.html#features I know what it's supposed to do, but I was wondering if it had any ALT-potential? Since it's designed to pick up electrons, is it sensitive to light? And if so, how so.... Wouldn't it reason that the resolution would be astronomical? Curious indeed. Just something to ponder.
