Students will take two photos. One photo will be of an object or person, and the other will be of something that shows texture. The photo that has texture should be an up close photo of just the texture (rust, erosion, cracks, etc). They will then use their channels layer to create a distressed effect on their photo.
Students will need to use a screenshot to save file. In order to screenshot an image, hit printscreen. Then open paint under the start menu. Select paste, then save as a jpeg.

Step by Step:
Open up texture, go to image, adjustments, hue\saturation. Take the saturation to the left to make it grayscale. Then go to image, adjustments, curves. Make it black and white by taking the points to the bottom and the top. Go to Select (at the top) the hit all. Edit, Copy, and then click on your photo.
Double click on your background layer, hit ok. Go to the top, Layer, New, Layer (make this layer white using your paintbucket). Drag this layer below your photo.
Click on your photo layer, hit Channels (by your layers tab), then look at the bottom. Create new channel (it will appear as a black box). Then go to Edit, paste.
Click on the layers tab so that you see your photo and white background. Click on your photo layer so that it will be highlighted. Hit your delete button on your keyboard, then go to Select, Deselect.
If you would like a different color, go back to Channels. Look for the arrow and lines icon, the hit Channel Options.
