In my previous post, I showed you an easy way to convert stereoscopic prints into an animated GIF for viewing on computers, tablets and smartphones.
This time, I got the opportunity to convert old stereoscopic slides taken with a Kodak Stereo camera similar to this one. The photo below appears to be of Girl Scouts in a school parade in Mount Prospect, IL circa 1957.
Scanning the images was a little more difficult than scanning standard 35mm slides because these images were slightly smaller and mounted in an old format.
I used an Epson v600 to get the images I wanted.
(You may notice that the images are flipped from the first image. That’s because the other side of the slide is labeled “view from this side.”)
The two resulting images were significantly different. This was not a problem when viewed with a Kodaslide Stereo Viewer since your brain would handle the mismatch, but this is a big problem with viewing on a computer. For example, if you made an animated GIF of the raw scans, you would end up with this awful result:
But if you correct for the mismatch in a photo editing program (**update** you can also use Google Photos — see below), you end up with something more useful like this:
You can use websites like ezgif.com/maker or gifcreator.me to create GIFs like these (**update** you can also use Google Photos — see below). Be careful not to make it blink too fast or too slow. Also, in our case, the extra border distracts from the effect. Crop out the extra and you get this:
These programs can also fix the mismatch problem.
However the resulting photos require blue/red 3D glasses to see the effect.
(tip: the effect is better if the photo is further away).
And neither of the above methods are even close to the effect you get when you see these through a Kodaslide Stereo Viewer, but if people are successful in getting 3D immersion technology into your smartphone, you may see this old photography reborn in the new technology.
**Update sometime in 2016?**
Here is a photo for you for those of you who have a Google Cardboard viewer. The effect is closer to the old slide viewer, but the visible spaces between the pixels reduces the effect in my opinion.

I’m always looking for easier ways to do things. It turns out that Google Photos creates a pretty good aligned animation. This eliminates the need for a photo editing program to align the images and a program or site to create the animation.
- Upload your scans to Google Photos
- Select the images using the checkboxes
- Select the + icon at the top right and select Animation
Don’t forget to download the animation as any online service can go away at any time.
The animation is slow, but arguably more pleasing than the fast animation, and extremely easy. Google Photos had trouble with my higher resolution scans (3000×3000), but no trouble with medium resolution (1500×1500) and below.
