Converting a Holmes Stereo Card to an Anaglyph ImageCopyright © 2003 Robert A. Swirsky. All rights reserved Using Callipygian 3D photo editing software, its easy to take a scanned in image of a Holmes stereocard and convert it to an anaglyph (red/cyan image). |
Step 1.
Scan in a Holmes Stereocard
Scan in a stereocard and save
the result to a file. For example the image below is a stereo picture of
ducks taken in
Figure 1. A stereo picture of ducks taken in |
Step 2. Start Callipygian 3D and drag the stereocard
file into both the left blue image region and the right blue image region
Figure 2 Callipygian 3D with the same stereo card
loaded into both the right- and left-hand panels. Note the selection
rectangle. Use your mouse to drag/drop the stereo card into both the left and right halves of Callipygian 3D. Choose Selection Style: Arbitrary in the Selection Style dropdown. Draw a selection with the mouse around the left hand portion of the left hand image. Then, move the mouse into the selection in the right hand image and slide the selection area over to the right hand portion of the right hand image. |
Step 3. Select Preview 3D -> Anaglyph on the main menu
Figure 3 Anaglyph Preview Use the horizontal and vertical sliders to make the object closest to you (the lower left-hand duck) converge. You may choose to slightly exceed this point on the horizontal axis if the objects in the background diverge too much. Put on your 3D glasses (red/cyan) and experiment with the settings that appear most comfortable and natural. If it is impossible to line up the the images, close the Anaglyph view and reposition the RIGHT selection. Then select Preview 3D->Anaglyph again. (The sliders allow only for a 10% movement in each direction) |
Step 4. Save your Image with File -> Save
3D view on the main menu
Select File->Save 3D view on the main menu and save your complete anaglyph.
