The orange mask is present in color negatives to limit the contrast of the

Photographic reproduction technologies, whatever they may be, cannot capture
the full range of detail from light to shadow that your eye can perceive.
Photographic films are limited in the range of tones they can capture; color
photographic paper is even more limited.

reproduced with good results on color photographic paper. If you attempt to
print a negative which does not have this orange mask onto standard color
paper, the resulting photograph is unacceptably contrasty, and is usually blown
out in the hilights. (This is often the case with prints that are made, for
example, directly from color transparencies, without the use of an
