Photoshop Elements SIG - 3-17-10

This is my first post to the Blog in a few months. Sorry I will try and do better in the future.

I demo'ed a technique for removing a color cast in an image. The steps are:
1. With the image open that has a color cast. Dupliclate the background to a new layer. I use the shortcut control+J
2. In the Filter menu choose Blur > Average. This creates an image with all the colors in the image averaged to a single color. This should be gray for an image without a cast.
3. Add a Levels Adjustment layer. Do this by clicking on the Ajustment layer icon at the bottom of the Layer's panel and by choosing Levels or from the Layers menu, Add Adjustment Layer.
4. The Levels Adjustmet Layer dialog box has three eyedroppers on the left side. The middle one is the gray eyedropper. Click on this to select it and click anywhere in the image on the background copy layer. This makes the adjustment to neutralize the color to gray on the background copy layer.
5. As we now have the adjustment we need in the Levels Adjustment layer either delete the background copy layer or turn it off by clicking the eyeball icon on that layer.
6. This applies the Levels adjustment to the image removing the color cast.

I showed three plugin filters for Photoshop Elements. They were

Topaz Labs Adjust 4, Simplify 2, Clean 2 and Detail 2.
