Applying a Sobel effect
You can use the Sobel effect to create a highlighted outline of your image. After creating a black image, the effect uses colored lines
to outline the detail of an image where significant color differences exist. Greater differences between colors in the original image
produce brighter outline colors. (The Sobel effect is similar to the Edge Detect effect, but produces sharper and brighter outlines.)
To use the Sobel effect:
1. In Edit mode, in the Add group, click Special Effect.
2. Click Sobel.
3. Do one of the following:
Click Done to accept your changes and close the pane.
Click Cancel to discard your changes and close the pane.
Applying a Solarize effect
You can use the Solarize effect to simulate the effect of overexposing an image, as though the film was exposed to light before
developing. You can select or change the Solarize options to apply this effect to your image, and save your options as a preset for
use at another time.
To apply a Solarize effect:
1. In Edit mode, in the Add group, click Special Effect.
2. Click Solarize.
3. On the Solarize tab, drag the Threshold slider to specify the brightness threshold of the image.
4. In the Effect area, specify which pixels you want to adjust by selecting one of the following options:
Solarize: adjusts pixels located above the specified threshold option. The effect takes any pixels above the threshold
and replaces them with their negative value. When you solarize an image, a higher threshold value sets a brighter
threshold, and colors need to be brighter to be overexposed.
Lunarize: adjusts pixels located below the specified threshold option. The effect takes any pixels below the threshold
and replaces them with their negative value. When you lunarize an image, a higher threshold value sets a darker
threshold, and colors do not have to be as bright to be overexposed.
5. Do one of the following:
Click Done to accept your changes and close the pane.
Click Cancel to discard your changes and close the pane.
Applying a Stained Glass effect
You can use the Stained Glass effect to divide your images into fragments of a random size and shape, to give the photo the
appearance of a stained glass window. You can control the size and position of the fragments. You can save your options as a preset
for use at another time.
To apply a Stained Glass effect:
1. In Edit mode, in the Add group, click Special Effect.
2. Click Stained Glass.
3. On the Stained Glass tab, set the options as described below.
