How To Prepare Your Own
3D Stereo Images for Red/Blue Glasses

  1. Scan in, or otherwise aquire the original image. On old stereo scope slide this will be one image of both the left and the right images together on the cardboard carrier. The Mode of the Image should be Greyscale.
  2. "Select" the left image and use Edit/Copy to copy the selection to the clipboard.
  3. Use File/New to create a new, blank image in Photoshop or other editor. (the commands here are for Photoshop)
  4. Change the Mode of the new, blank image to RGB.
  5. Use the Window/Channel command to open the Channels control window. Select the Red Channel and display the Red channel. ie. Click on the little eye and also on the square area to the right. Use Edit/Paste to place the left image into the Red Channel.
  6. "Select" the right image and use the Edit/Copy to copy the selection to the clipboard.
  7. Select both the Green Channel and the Blue Channel of the New Image. Click on the little eye and the square for both Channels. This is acomplished by holding down the shift key during the selection. Use the Edit/Paste to place the right image into both the Green Channel and the Blue Channel simultaenously. (if not supported by your software, you can paste to each channel seperately.
  8. Look at the resulting image, (with RBG all turned on) with the colored glasses, red on left eye.

As you can see from the above steps, the objective of the process is to get the left image into the red channel and the right image into both the green and blue channels. If anyone has success using this process please send be your URL of the resulting image and I will list them here.
