LGHT
155
COLOR
LGHT — adjust LiGHTness
Format
LGHT mode, degree;
Parameters
mode:
mode of lightness adjustment:
0 = gamma control
1 = contrast control
degree:
degree of saturation level:
number from –10 to 10 (Default is 0)
Function
The LGHT command controls lightness and darkness balance based on the specified
parameters. The gamma and contrast can be set independently of each other.
In gamma control mode, the color bars below represent the lightness gamma variation
using hue R as an example. The top color bar represents the default lightness variation (γ
= 1.0) with its median indicated by the symbol. The left side represents the lower
lightness range and the right side the higher lightness range. The middle color bar is an
example lightness balance made brighter (set to γ
> 1.0). The bottom color bar is an
example lightness balance made darker (set to γ < 1.0).
Varying the lightness gamma allows the lightness of the image to vary. (You can achieve
lightness variation, such as making dark images brighter by reducing low lightness areas,
for example.)
In contrast control mode, the color bars below represent lightness contrast variations
using hue R as an example. The top color bar represents the default contrast variation
with its median indicated by the symbol. The left side represents the lower lightness
range and the right side the higher lightness range. The middle color bar is an example
application of strong contrast to the top bar. The bottom color bar is an example
application of weak contrast to the top bar.
