Accidental Stereo Images... VIS + UV

kds315* · Expire: 2021-03-09

When I am doing lens tests, I usually take exactly the same images. Here I was comparing two similar lenses,
a Coastal Optics / Jenoptik f4.5/105mm and an UV-Nikkor 4.5/105mm.

Since I am used to see and use crosseye 3D stereo images to compare, this really catched my attention, as it was
unintened, but due to some effect, it turned out 3D!!

Just in case you have not yet tried to do 3D stereo, here a little "how to":

1) look at the image, center on the middle gap between them (with your glasses on that you need for reading this sharp = in focus)
2) place the pointer finger at your nose tip without changing your viewing
3) now still looking straigt to the image, try to focus on your finger
4) move the finger towards the gap between the images
5) follow the finger while keeping focused on it
6) at a certain moment an image "between the images" will appear (looking three dimensional); your finger will be approx. 20cm = 8 inches away from your nose (depending on viewing distance from screen)
7) move your concentration towards that "image between the images" and leave it there (and remove your finger then without changing your viewing position...)
Cool

that's it...
