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:
On the Edit Panel, click Effects, and then double-click Sobel.

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 On the Edit Panel, click Effects, and then double-click Solarize.
2 On the Solarize tab, drag the Threshold slider to specify the brightness threshold of the image.
3 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.
4 Do one of the following:
•Click Done to accept your changes and close the Solarize tab.
•Click Cancel to discard your changes and close the tab.
