KODAK DIGITAL GEM Airbrush Professional Plug-In Blending Controls

At any time you can reset all of the adjustments to their default positions by clicking the Default button. The options you choose will remain changed as long as you click OK and apply the changes. If you click Cancel the settings will revert to the setting in place when you last opened the Plug-In.
Blending Controls
If you are using Windows, you can move a slider in single increment steps using the left and right arrow keys on your keyboard once you have selected it by clicking on it or using the tab key. You can also use the page up and page down keys to move the slider in larger increments, or the home and end keys to move the slider to the minimum and maximum values. This feature is not currently available using a Mac.

Blending - This slider determines how much of the Plug-In effects will be applied to the image. At zero percent it is the same as not running the Plug-In at all, at one hundred percent it is applying as much effect as possible. Move the slider back and forth to apply as much effect as you desire.
Blending Modes - The Blending mode choices control how the smoothed image is blended with the original. The Lighten mode lets light details come through unaffected by the Plug-In. If you have darker details (as complexion problems) the Lighten mode will smooth them out but lightened details like reflections are unaffected. If you have reflections (details) on a model's face and you want them to remove, and you want shadows to stay use the Darken mode. If you want to soften the shadows and reduce the reflections use the Normal mode.

Technically, Normal mode blends the images by averaging them, weighted according to the blending slider. For example, if the blending slider is set at 75%, the final image will be 75% of the smoothed image and 25% of the original added together. Normal mode is the best choice for images where the maximum amount of smoothing is needed.  The Lighten mode blends the original and smoothed by choosing which is lighter, weighted by the blending slider. For example, if the blending slider is set at 75%, if the smoothed image is lighter than the original, the result will be 75% of the smoothed added to 25% of the original. Where the smoothed image is darker, the result is equal to the original. The lighten mode with the blending slider set at 100% is usually the best choice for portraits, because it preserves the highlights. The Darken mode works like the lighten mode, except the smoothed image is blended only in areas where it is darker than the original. This mode tends to be most useful for artistic effects, like smoothing a dark background. The blending modes and slider work very similarly to the layer blending modes and sliders in Photoshop.
