Creating Gradient Images for PlasmaWipe Effects

Histogram examples: image that will not animate at a constant speed (left) and image that will animate at a constant
speed (right)
Depending on the effect you want to create, the image associated with either type of histogram might
create an acceptable animation as long as it uses the full range of gradients.

If you want to change the speed of the wipe, you can use keyframes to control the Level parameter.
You can use Adobe Photoshop commands such as Equalize, Auto Levels, or Auto Contrast to
increase the range of gradient values. For more information, see your Adobe Photoshop
documentation.
Adjustments such as Equalize might result in a histogram that has a wide range of gradients but that
has many gaps in the values. In a short wipe effect the gaps are not noticeable. In a long effect, the
gaps might create doubled frames in the animation. You can use a blur filter such as Gaussian Blur to
smooth out the range. For more information, see your Adobe Photoshop documentation.

Testing a PlasmaWipe Animation
You can use the following procedure in Adobe Photoshop to preview the animation for your gradient
image. This example uses the Horiz Twirl image from the PlasmaWipes folder.
To test an animation:
1. Select Image > Adjustments > Brightness/Contrast.
The Brightness/Contrast dialog box appears. The following illustration shows the image and the
Brightness/Contrast dialog box.
2. Move the Contrast slider all the way to the right to view the animation with hard edges.
