Most photographic emulsions are sensitive to this range of bands. Negative is the image produced on a photographic emulsion by the product of exposure and development, in which tones are reversed so that highlights appear dark and shadows appear light. Negative carrier supports the negative between the light source and the enlarging lens of an enlarger. Negative lens is a simple concave lens that causes rays of light to diverge away from the optical axis . Neo-coccine is a red dye used in retouching to stain the gelatin.
Neutral density is a technique which makes possible shorter printing times in color printing.
Neutral density filter describes a gray camera filter which has an equal opacity to all the colors of the spectrum and so does not affect the colors in the final image. It is used to reduce the amount of light entering the camera when aperture or shutter settings must remain constant. Neutral filtration in color printing is the filtration at which color balance is achieved, rendering a neutral gray ion the film image as a neutral gray on the photographic paper. Neutralizer is a chemical designed to counteract and make inactive another chemical solution. New Objectivity is an approach to the subject matter of photography originating in Germany in the 1920s.
