TARGET WHITE and TARGET BLACK
These two parameters determine the highest and lowest levels of luminance for target images
(outputs). (See figures below and in the next page.)

Determines the maximum value of luminance for outputs.
The maximum luminance value of the image after
60.0 -
correction should approximate this value.
100.0%
The larger the value, the brighter the image, which may
(0.5%)
however cause the image to be overexposed. The smaller
the value, tones of the bright part are kept. However, the
overall obtained image may be dark.
Determines the minimum value of luminance for outputs.
The minimum luminance value of the image after correction
should approximate this value.
0 -
The larger the value, the dark area in pictures will appear
40.0%
brighter, which may however lower the contrast and the
(0.5%)
noise will become apparent. The smaller the value, the
higher the contrast, which may however cause the image to
be underexposed.
