Dear ng,
concerning the available luminance range of slide films Hunt writes in
'The Reproduction of color' that
'...the effect of the dark surrounds in reducing the apparent
contrast of projected transparencies is such that this range of
reproduction luminances, 2,1 log units, is equivalent to only about
1,4 lof units in scene luminance...'.
Now I understand that slide film must have a high gamma value/steep
characteristc to compensate for the reduction of apparent contrast
caused by the dark surround, but can anyone imagine how this affects
the range of available scene luminances?
Thanks a lot for all your input!
