ashw_justin Posted July 9, 2004 Posted July 9, 2004 So a photo on rockclimbing.com inspired me to experiment with stereo photography. Basically you just take two photos of something, with about 3 or 4 inches lateral difference, but focused on the same point. Then you line the images up side by side and cross your eyes to see the 3d image. I was thinking about doing this for mountains and rock routes. Has anyone tried that (outdoor shots)? Quote
assmonkey Posted July 9, 2004 Posted July 9, 2004 I think it would be hard to climb with your eyes crossed. - a s s m * n k e y Quote
cj001f Posted July 9, 2004 Posted July 9, 2004 2.5 inches lateral seperation will allow to reproduce the orginal depth of the object (larger/smaller seperation will result in magnification) Quote
ashw_justin Posted July 9, 2004 Author Posted July 9, 2004 Yeah I just went with a 4-degree difference, which in 44" radius came out to about 3". Quote
swaterfall Posted July 9, 2004 Posted July 9, 2004 Why don't you put some of that thought-energy into figuring out how to get some dough together to buy a real set of ice tools. Quote
ashw_justin Posted July 9, 2004 Author Posted July 9, 2004 Haha. No way dude I'm gonna rock the ice old skewl. Quote

Stemalot Posted July 9, 2004 Posted July 9, 2004 hum...the effect is not very dramatic, but interesting nevertheless Quote
ashw_justin Posted July 9, 2004 Author Posted July 9, 2004 Yeah well the subject isn't very interesting, it's the idea... Quote
Dru Posted July 9, 2004 Posted July 9, 2004 Im pretty sure lurker Andy Cairns had or has some set up for taking stereo pics with two point and shoots taped together. Quote
ashw_justin Posted July 9, 2004 Author Posted July 9, 2004 (edited) uh... cross your eyes more... or go to my uw site it has a couple of easier ones... Edited July 9, 2004 by ashw_justin Quote
cracked Posted July 9, 2004 Posted July 9, 2004 I think it's because I view stuff in the foreground with my left eye, and stuff in the background with my right. So I lack depth perception and your silly photography won't work. Quote
Cairns Posted July 9, 2004 Posted July 9, 2004 Im pretty sure lurker Andy Cairns had or has some set up for taking stereo pics with two point and shoots taped together. Long ago in Chicago I saw slides taken with a real stereo camera. From the Bugaboos. I just wonder why a climbing magazine hasn't tried that approach. Probably for an excellent reason. My stuff looked okay when there was a subject with a hand and arm buried in a crack and a big drop underneath. You should really get a specialist camera with good lenses, though. Or find a friend with a camera like enough to yours who will let you lash them together. Quote
Jim_T Posted July 9, 2004 Posted July 9, 2004 The best way to do this is with an old stereo camera - for example you can find lots of "Stereo Realist" cameras on Ebay for around $120. The camera has two lenses and takes two side-by-side pictures simultaneously. Normally you load it with slide film, and then look at them through a viewer (similar to the ViewMaster slides). The effect is amazing (much better than crossing your eyes to look at a print). I've taken tons of pictures like this. The problem is that they are hard to share on the web (slide scanners are expensive) and hard to view without the viewer. And, the camera is heavy! Quote
ken4ord Posted July 9, 2004 Posted July 9, 2004 That came out pretty good, I was amazed that I could still focus in the 3D image as fast I did. The same technique is used for visualizing large molecules in 3D. Cracked and anybody else, what you got to do is cross your eyes so that the two images cross into one and hold (about 12 inches from your screen will make it easier), you will still see the original images off to the side. Give it a little time it takes a little time to focus on the middle image as the two outside one go out of focus. when that happens you will see the image in 3D. Nice job ashw_justin Quote
Dru Posted July 9, 2004 Posted July 9, 2004 i just put my work stereoscope up against the screen in our other office they have these funky shutter glasses that let you look at digital sat photos in 3d. its really cool for scoping secret valleys full of unknown big walls Quote
ken4ord Posted July 9, 2004 Posted July 9, 2004 So with these shutter glasses you don't need two images? or are you just being Dru and there is no such thing as shutter glasses? Quote
Dru Posted July 9, 2004 Posted July 9, 2004 no you do need two images but they alternate full screen and the shutters flicker open and closed. its sort of like 3d glasses but without the red and blue lenses. the flickering of the images and the shutters are synchronized so each eye only sees one full screen image Quote
dukiebird Posted July 9, 2004 Posted July 9, 2004 this ain't working. its like those damn magic eye things, where I'm looking for a unicorn or something and end up seeing a bunch of squiggly dots and stuff. I don't think its possible to cross my eyes enough to make it line up, trying to make it work almost gave me an eyeball hernia. Quote
ken4ord Posted July 9, 2004 Posted July 9, 2004 Dude you don't have to cross them that far, cross them so the you see two images of the ice axes, them relax your crossing so that they merge (the right side of the left image and left side of the right image), then allow your eyes to focus on that central image and you will see it in 3D.
