191:" (reducing the amount of light to a specific area of an image by selectively blocking light to it for part or all of the exposure time) and/or "burning" (giving additional exposure to specific area of an image by exposing only it while blocking light to the rest). Filters, usually thin pieces of colored plastic, can be used to increase or decrease an image's contrast (the difference between dark tones and light tones). One method of photographic printing, called "split filter printing," is where the photographer determines two separate exposure times using two separate filters (typically a 0 or 00, and a 5) to create a single print. This method allows the photographer to achieve a broad tonal range, with detailed highlights and rich blacks. After exposure, the photographic printing paper (which still appears blank) is ready to be processed. 27: 39: 127: 1970: 1981: 165:
Color print paper, being sensitive to all parts of the visible spectrum, must be kept in complete darkness until the prints are properly fixed. A very dim variation of safelight that can be used with certain negative color materials exists, but the light emitted by one is so low that most printers do
