If you do not have a stereoscope, here is one way to do it if you have a photo processing software such as Photo Shop or Paint Shop Pro and a pair of strong reading glasses (3 to 4 diopter lenses): Save the two images separately on your hard drive, open them into the photo processor window side by side. While wearing the glasses, grab and move one of the photos until a prominent feature on it seems to overlay the same feature as seen on the other photo. Eureka, you have stereoscopic view that is comfort to your eyes.
Yes. You have to use Photoshop or another very high-end graphics editor. Start with the left image. Cut the whole picture and then edit the red channel and paste it in. Copy the right picture then go back to the first image, edit the blue channel and drop it in.
Dig through your kids' top drawer and swipe the stereo glasses they saved from the Spy Kids movie.
I'd do it for these, but I don't have any web space that could handle the server load here on FR.
