I decided to take up making Anaglyph 3D images and my search on how to do it mostly turned up recommendations to buy this software or that software. One side described a process using (full blown) Photoshop and its Advanced Blending feature to separate the color channels. But alas, Photoshop Elements does not have Advanced Blending. Never fear... Levels to the rescue. My work flow is as follows:
1. Shoot an image from each of two positions at three or four inches apart, left to right, and load into Photoshop Elements.
2. Use the leveling tool on the same reference point in both images to make sure they are horizontally aligned the same.
3. Using the right image as the background, drag the left image onto it.
4. Convert the background to a layer. You now have a layer for right and above it a layer for left.
5. With the left layer selected, choose Enhance > Adjust Lighting > Levels. In the Channel Drop Down choose Red.
6. On the Output Levels slider, move the 255 stop all the way to the left (0.)
7. With the right layer selected, choose Enhance > Adjust Lighting > Levels. In the Channel Drop Down choose Green.
8. On the Output Levels Slider, move the 255 stop all the way to the left (0.)
9. With the right layer still selected, Adjust the Blue Channel the same as the Green.
10. Select the top layer (Left) and set the opacity to 50%.
Edit: 10.5 At this point you can use the arrow keys to nudge the layers into better alignment, if needed.
11. Press and hold Shift, Control, Alt and press E to get a merged layer at the top of the stack.
12. Choose Enhance > Adjust Lighting > Brightness/Contrast to lighten as needed.
13. Save as a jpeg.
I went out this morning and grabbed a couple of shots to try this out. The results are in the gallery:
