OLD DOGS NEW TRICKS HOMEWORK Colored Reliefs with Masks August 18, 2001 This ribbon awarded for my finished homework personally by MaggieA1. Thanks loads! I love it! I have just joined the PSPUG and signed up for classes that will start in September, but I couldn't wait. I have started coming to classes in August. I got all mixed up on this tutorial in class, but have now figured it out. After I got going I wanted to see what all the different channel splits would do. This was an interesting lesson that helped me see the possibilities of the color channel splitter. Thanks to all the PSPUG Staff who helped me through the class and came up with this lesson. If you would like to try this tutorial go here.

This was the original picture. I did not like the light streak on the left side of the picture so before I started I selected a portion of the picture and then resized it to the original height. But, now it is not quite as wide. This is the picture using the green channel of the RGB split mask. This is the one that we did in class. This is the picture with a red channel of the RGB split mask. I don't really see much difference in this one from the green one. This is the picture with a blue channel of the RGB split mask. The differences on this one are minor This is the picture with a cyan channel of the CMYK split mask. This one does not work well with this photo. This is the picture with a magenta channel of the CMYK split mask. I don't like this one either. It just looks like somebody jiggled the camera while taking a picture of a light colored bird. This is the picture with the yellow channel of the CMYK split mask. As you can see this one does not work very well either for this photo. On this picture I used the black channel of the CMYK split with the mask invert not checked. This time I checked the invert mask data. This one definitely has more possibilities. I was wondering what the splits of the HSL would look like. So I just started experimenting. This one is the hue channel with the invert mask data turned on. This one is the saturation channel with the invert mask data turned on. This one is the saturation channel with the invert mask data turned off. Wow! This is an interesting effect. This one is the lightness channel with the invert mask data turned on. This one is the lightness channel with the invert mask data turned off.
