chandanlog(3C): Stereoscopic Hard Disks

30 Sep 2006 Stereoscopic Hard Disks

Experimented with stereoscopic photography. It is easy: (0) take two successive photos by laterally shifting the camera by 7cm. Open the left and right image in GIMP, (1) paste side by side, (2) crop any unwanted portions, (3) align the images using horizontal guide rules, (4) resize the image to about 14cm in width. You are done.
Stereoscopic Disks

To view the 3D photo, focus on the eye away in between the images, till both overlap to form a single 3D object. (it seems about 10% of people will not be able to see this way, so don't worry if you don't see the effect)

The object is an assembly of bad old hard disk platters - joined tightly together with tiny 5mm slits made by hacksaw. No glue or any other material used. Initial version of this sculpture had a plastic base. Later it occurred to me that a folded platter could become the base, provided I balance the center of gravity through its semicircle. Next version might be to hang it by thread, so it can gently rotate, forming a kinetic sculpture.

I am able to see the 3D photographs. I am seeing three such images instead of one.

Only the middle one will have 3D effect - i.e depth of field, ignore the rest.

Hi, i think i've made something pretty special - normally stero images have to be small - for your eyes to be able to view them - but i've made a FULL SCREEN image viewable using an extention of this technique. I would greatly appreciate your thoughts. And also some amazing large 3D images would also be appreciated. Cheers. Please note - this was posted on july 2007 and the link may have died, but if so, no doubt the technique was developed so check out the root of the website www.nicholaswhitworth.com. Which i will maintain unless something terrible happens. Nice 3D hardrive. accomplished photography... nicholas. and if that doesn't work. . . http://www.nicholaswhitworth.com/temporary_display/3d_strip_wide%20(from%20bridge).html

Very sweet trick. I must get into Gimp and throw away my old Paintshop Pro Version 6. Those platters would make a great mobile hanging from the ceiling. They would cause very interesting replections.

Thanks for the tutorial.

there are reflections in the coins that take away from the combined image. I think you could have also taken them a little further apart and it might stick out a little more. I find if i go a little over the tables that i found I get a little more action. and the images on the sides arent 3'd there you cant just shift one image at a time you're shfting the whole plane of vision.
