From left to right: original image, after applying Value Invert
You can find this filter through
This filter inverts Value (luminosity) of the active layer or
selection. Hue and Saturation will not be affected, although the
color will sometimes be slightly different because of round-off
error. If you want to invert Hue and Saturation also, use
-> -> .
Note that hue and saturation can be distorted quite a bit when
applying twice this filter for colors with a high luminosity ( for
instance, HSV 102°,100%, 98%, a bright green, gives HSV 96°, 100%, 2%
after a first application of the filter , and 96°, 100%, 98% after a
second application) . Thus, you should not expect to be able to apply
this filter twice in a row and get back the image you started with.
