Photographic printer and method of making a filter for a photographic printer |
摘要 |
A method of improving uneven illumination in a photographic printer having an original image position and a light source to illuminate the original image position, which light source may illuminate the original image position non-uniformly, the method comprising: first forming a mask by exposing a photographic element to the light source and processing the element to form a negative image of the light source at a filtering position between the light source and the original image position; and positioning the mask at the filtering position. A second aspect of the method uses an electronic processor and gathered illumination data, to generate a mask.
