How is the UVCorder™ better than film for UV imaging?
A. Even under laboratory conditions, film-based UV photography is very inefficient in terms of the time it takes to get a good shot. When the film camera has the UV pass filter on it, the photographer cannot compose the shot, since the eye sees nothing through that filter. So the shot must be made using a tripod. The filter is removed for composition, and then is replaced before the exposure is made. The exposure value must be guessed, although filters like the UG-1 have a filter factor of about 6 stops with sunlight illumination, and using 6 stops of compensation often works. Still, this technique requires bracketing, which consumes a lot of film. Black and white film is getting harder to find, and fewer and fewer labs process it. The UVCorder™ eliminates every one of these problems and adds video capability as well. The primary difference is resolution – the UVCorder is a 640×480 imager. This is 0.3 megapixels, which is a lot less than the level to which film can be digitized.
