Adjusting Brightness and Contrast
Darkened
Note
Highlights may be lost if you brighten the image too much, and shadows may be lost if you darken
the image too much.
Contrast
Contrast is the degree of difference between the brighter and darker parts of an image. Increasing
contrast will increase the difference, thus sharpening the image. Decreasing contrast will decrease the
difference, thus softening the image.
Move
(slider) under Contrast to the left to decrease and right to increase the contrast of the image.
You can also enter a value (-127 to 127).
Decreased contrast
Note
Increasing the contrast is effective in adding a three-dimensional feel to soft images. However,
shadows and highlights may be lost if you increase the contrast too much.
Note
