These are side by side stereo pairs, from which I made "stereo cards" (the kind that you use with the old-style stereo viewers). If you want to have some of your own stereo cards printed, you will need to order 5x7" prints - uncropped - and then trim off the white portions (stereo card format is 3.5"x7"). Contact me if you have any questions (rickshel@pacbell.net). Alternatively, you can try to "free-view" the stereo pairs - try to let your eyes focus on infinity, and let the two images merge into one. When they have fused together, relax and slowly focus. Try it, but be patient - once you get the hang of it, it is really simple!
