Adjustments Menu

The commands in this menu are meant for adjusting the image in various ways to get the colors to look the way you want.

Adjustments

Pagoda

This image will be used to illustrate what the various adjustments can do:

Original Image

Pagoda

Auto-Level

This can be used to equalize the colors of an image so that overly dark or bright images are brought back to a normal range. This is equivalent to using the Levels adjustment and then clicking the "Auto" button.

Example

Auto Level

After using the Auto-Level adjustment, which has no configuration options

Brightness / Contrast

This may be used to make the colors in an image brighter or darker, or to make colors stand out more or less from those around them.

Example

Brightness

Image with increased brightness


Contrast

Image with increased contrast


Brightness and Contrast

Image with increased brightness and contrast

Curves

This adjustment is used to adjust the luminosity and/or RGB (Red, Green & Blue) curves of an image. For greater discussion of this functionality, please visit the Curves section.

Black & White

This adjustment removes all color, effectively making the layer black & white.

Example

Black and White

Image that has been desaturated

Hue/Saturation

This operation may be used to change the saturation of colors, as well as rotate the hue of the image. Additionally, it allows the adjustment of lightness, which is similar to but not the same as brightness.

Example

Hue Saturation

Image after the Hue was set to 88 and the Saturation was set to 158

Invert Colors

This adjustment is very similar to a negative of a photo. Applying it a second time produces the image again.

Example

Invert

Image after it has been inverted

Levels

This operation is used to adjust the color range and gamma of an image. For greater discussion of this functionality, please visit the Levels section.

Posterize

This adjustment allows you to reduce the number of available color values that each pixel may use. Normally each color channel has 256 possible values (0 through 255), but with this you can restrict this to a range from 2 to 64 values. This gives your image a "posterized" or even a retro or "faux dithered" look.

Example

Sepia

This adjustment turns the image black & white, and then adds a sepia tone. This can be used to give your images an "aged" look.
