Some bug cross-eye stereograms

Post by LordV »

When possible I quite frequently do cross-eye stereograms of bugs. These are done using the cha-cha method of taking one pic then moving the camera laterally about 1/30th of the subject distance and taking another pic. I do these on untreated bugs and hope they don't move between shots. If possible I also use focus stacking on the individual shots.
I use a freeware prog "sterephotomaker" to align the stereo pairs.

These can be viewed as is by slightly de-focusing your eyes and then cross them until an image appears in the middle and then relax your eyes to get a stable 3-D image. It's worth the trouble!
But don't overdo it if you have difficulty- try again later.(headache warning)

If you manage with the smaller pairs try clicking the image for a larger version.

Some pretty neat stuff there Brian, a little rough on these old eyes of mine but pretty neat just the same. :D

Thanks Ken and Rik.

I just find these 3-D shots very evocative of the moment I was taking the pics.

I've never been able to see these as 3D. Have you seen the free 3D actions on http://www.atncentral.com?

The freeware prog I use Stereophotomaker will produce anaglyphs for viewing with colour filter stereo glasses assuming that's what the PS action does ?
I just don't like the colour loss you get with those.
One thing to try with these is sit about 1.5 feet from the monitor and put a finger about 4" in fron t of your nose so it's in front of the stereo pair. Then focus on your finger. If you notice a third image appear in the background between the two originals then you are halfway there to getting the 3-D image. Try to maintain the third image whilst sliding your finger out of the way. Once you have done this once , it's like riding a bike and your eye/brain remember how to do it.

Nice shots of the insects. I don't have stereo vision, but I'm on to the gag now. So you guys can stop pretending about this depth perception thing, I figured out the joke! :lol: :P :twisted:

Thanks :)
Dam you realised we take control of your web cam whilst you are going cross-eyed :)

I like them. Especially the third one. Good composition, lighting and stereo experience.
