I had earlier posted about making use of Max-script for 3Ds max to generate an anaglyph stereoscopic 3D images using 2 simple images. Now this is easy but requires coding and a copy of 3Ds max and is sometimes very time consuming. A much simpler way is to use Photoshop. For this tutorial i will use the same images as in the previous example but you can use any images you like provided that they are recorded properly.
Left Eye Image :
Right Eye Image:
Here are the steps for combining using Photoshop CS4 (will also work for most earlier and later versions).
Step 1: Open both images in Photoshop.
Step 2: Open and select the right eye image and under channels select green and blue channels(use Shift for multiple selection). Press CTRL+C to copy.
Step 3: Open and select the left eye image and under channels select red channel .Press CTRL+V to paste.
Step 4: Make sure the eye icon is turned on for all the channels.
Step 5: Save left eye image as final image and done.
Note : will soon be posting how to combine footage (images and video) into stereoscopic 3D using After Effects.
