Set Up Your Capture > Capture Effects > Color Correction Effect

Color Correction Effect

For information on how to access effects, see Accessing Effects.

SnagIt gives you the option of creating a customized Color Correction effect allowing you to change the capture's brightness, contrast, hue, saturation, and gamma properties.

To set up a Color Correction effect

From the Mode toolbar, select the Image Capture mode button.
Select the Effects button within the Profile settings pane to see the dropdown menu of options.
Select Color Correction. The Color Correction task page will display.
Customize your effect using the available settings and then select OK.
You will return to the main SnagIt view. Set your Input and Output capture options.
Select the Preview Window button from the Options toolbar.
Select the Capture button to invoke capture.
Once the capture is taken, it will be displayed within the Capture Preview window with the effect applied to it.
Select Finish to send your capture to the output source. Or, select Cancel to delete the capture.

Tip: Once you have taken a capture and viewed it with the Capture Preview window to ensure that it is the exact effect that you desire, then you can always disable the Preview Window option so you no longer have to view the capture in the Capture Preview window each time you take a capture.

Tip: To disable a Color Correction effect, select the Effects button, and then select Color Correction. Within the task page, set all options to zero (with the exception of the Gamma option which should be set to 1.0). Select OK.

Color Correction Effect Options Description Table

The following table describes each of the Color Correction options along with its use.

Option	Description & Use
Brightness	This option changes the intensity (brightness) of the selected image. Lighten or darken the image using the Brightness percentage slider, or by typing a new value in the percentage box located to the right of the slider. Use the preview image to see the effect of the effect.
Contrast	This option changes the contrast between light and dark portions of the selected image. Increase or decrease the contrast using the Contrast percentage slider, or by typing a new value in the percentage box located to the right of the slider. Use the preview image to see the effect of the effect.
Hue	This option changes the hue of colors in the selected image. This is similar to rotating a color wheel to select a different mixture of colors. Change the hue of the image using the Hue percentage slider, or by typing a new value in the percentage box located to the right of the slider. Use the preview image to see the effect of the effect.
Saturation	This option increases or decreases the saturation of colors in a selected image. Saturation is the quantity of a color in pixels, from gray at the lowest saturation to rich color in the highest. Increase or decrease the saturation using the Saturation percentage slider, or by typing a new value in the percentage box located to the right of the slider. Use the preview image to see the effect of the effect.
Gamma	This option adjusts the intensity of colors in a selected graphic by changing the gamma constant that is used to map the intensity values. Gamma correction changes brightness using a logarithmic scale for visual perception. Gamma is a constant that is used to calculate the progression. For most CRTs, the gamma constant is in the range of 2.2 to 2.5. Increase or decrease the gamma correction using the Gamma slider, or by typing a new value in the percentage box located to the right of the slider. Use the preview image to see the effect of the effect.
