Use this menu selection to alter the hue, saturation, lightness, contrast, red, green and blue levels and gamma in an image.

 

 

All Tabs:

 

Apply. Select which areas of the image will be adjusted: All, Shadows, Midtones, or Highlights.

 

Save. Click to save the current adjustment settings. You will be prompted for a name, under which the settings will be saved. All saved settings will appear on the [Abrir] button flyout menu.

 

Load. Click to display the saved settings flyout menu and load previously saved settings.

 

Auto View. Automatically updates the main window when you make changes. This option is not recommended for older (relatively slow) displays.

 

Clear. Sets all controls to zero.

 

Last. Restores the last settings used to adjust an image so they can be used on the current image.

 

View. This button repaints the image with the selected changes.

 

Note: ThumbsPlus remembers the last values you used to adjust an image, so you can use them to adjust another, or as input to Batch Processing as a batch step.

 

 

Hue Tab:

 

 

Hue. This controls the overall hue (color) of the image.

 

Saturation. This controls the amount of color saturation. Lower saturation makes the image grayer.

 

Lightness. This control changes the overall brightness of an image. Use negative values to darken an image, and positive values to lighten it. Use the arrow keys or the mouse to change the value.

 

Contrast. This control changes the contrast; that is, the difference between the light and dark areas. Positive values increase the difference between them, while negative values decrease the contrast.

 

 

Tint Tab:

 

 

Red, Green, Blue. These controls modify the amount of Red, Green and Blue in the image. They work similarly to the Brightness control, but individually on each color channel.

 

 

Gamma Tab:

 

 

Gamma. This control changes the color values or gray levels in an image to provide for a specific gamma correction. The display itself doesn't change (because ThumbsPlus knows the new assumed gamma value, and adjusts for it!), but the image itself does. This is most useful if you have linear files (gamma = 1.0), and wish to make them "standard" GIF files (gamma = 2.0), so they will display reasonably correctly with viewers which don't provide gamma correction.
