Adjust Tonal Range

Adjust the tonal range to increase contrast by using the Adjust/Enhance > Auto Levels menu item. This function finds

out the darkest and brightest colors. It also ignores the top 1% darkest and brightest pixels in the image. Then, it

redistributes the values proportionally for each color channel. As it is done for each channel, it may introduce or

remove color cast.

If color cast is introduced, you can try to use the Adjust/Enhance > Auto Contrast menu item instead. This function

finds out the darkest and the brightest colors (ignores the top 1% darkest and brightest pixels) in the image, maps

them into black and white, and adjusts the color of every pixel accordingly. The calculation is not done separately on

each color channel; therefore, no color cast will be introduced or removed.

If neither of the above tools satifies your requirements, use the Adjust/Enhance > Levels menu item instead.3.
