Photo Printed On Canvas

Printing from a Slide or Transparency

Printing from a slide or transparency is similar to printing from a negative except that additional processing steps are added to form a reversal print.

Initial development of the print results in a negative image. This development is not followed by fixation, but rather the reduced silver of the negative image is chemically removed from the paper. Since the paper has not been fixed, the unreduced silver halide remains in the emulsion. To form the positive image, the paper is then exposed to light, which creates a latent image in the unreduced silver halide coating. This latent image is developed and fixed to form the positive image.

Standard print sizes

Standard photographic print sizes are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches. In the normal series, the long edge is the length of the short edge plus 2 inches (10" or less) or 3 inches (11" and above). The alternative Super series, denoted SnR has an aspect ratio of 2:3 (or as close as possible) and thus provides a better fit for standard 135 film (35mm) at sizes of 8 inches or above.

In Japan, the same print sizes (and several additional ones) are known by different names. The Japanese L is equivalent to 3R, while 2L — twice the size — matches 5R. KG represents the size of a traditional 4"×6" (4R) Japanese postcard (hagaki).^[1] The nP or cut (切り, kiri^?) series are defined in reference to a full page size (全紙, zenshi^?) of 457×560 mm, with smaller numbers (fewer cuts) indicating larger sizes.^[2]
