The RAW from a B&W sensor would BE the image although you could do various tasks to it after it were retrieved from the camera. It depends on the geometry used for the sensor. Still, it's an exciting prospect. AB On 10/3/06, B. D. Colen <bd@bdcolenphoto.com> wrote: > Thanks for clearing it up Mark.
