Vinca minor. (Stereo only)
I've been really tied up setting up a new/old microscope and I'm finally getting to the (not all that serious yet) "testing" phase. I grabbed a Vinca minor blossom to play around with. I did a few quick shots. What I found interesting is how, while they did not really "grab" me as 2-dimension images the stereo pairs were quite fun to look at. So with apologies to those who can't "see" these... here are a few (no retouching... straight out of Zerene).

Jacek,
Sometimes it helps to stare at the image on the screen, and then hold a pencil or your finger up at the center between the image pairs. Slowly move the pencil or finger toward your nose while trying to keep it in view with both eyes. This causes the eyes to cross. Then try to "lock" your eyes in that position while slowly diverting your attention to the screen image. With practice the images should "fuse" into a clear sharp stereo view in the middle. (Toward the outside, in your peripheral vision on either side, you will see a "blurred" non-stereo image. You learn to ignore that quickly).
If you simply cannot do it by such free-viewing" you may have some luck with a simple paper "device" called an "Elliot viewer".

These are "cross-eyed" pairs. The image on the left is the one that needs to be seen by the right eye, and the image on the right is the one that needs to be seen by the left eye. The nice thing about "cross-eyed pairs" is that many (most?) people can learn to see the stereo effect by "free-viewing", that is, no devices are needed. You need to cross your eyes so that each eye sees the appropriate image. Initially it takes some practice but once you learn the technique it comes pretty easily. (Although there are people that are not able to do it).beautiful, what is the need to view stereo pairs ?
