more anaglyphs.

Basically, I learnt the procedure myself. Shoot two pictures in slightly different angles, adjust the color in photoshop so that one is cyan, and the other is magenta. Then blend them in together, and viola, you have an anaglyph.

so the basic principle of an anaglyph is that you take a pic of the same thing as seen by each eye, and use them together, and filter out the info that the other eye sees from each eye using the anaglyph goggs, or two bits of cellophene.

Theoretically, if you take a pic of the same thing in two drastically different angles, and fuse them in together, you will also be able to see the thing from a totally different perspective using the same principle. Like, this picture is my attempt to get a picture to perspective if one eye was on your right temple, and the other eye was positioned in the bottom left corner of your chin.



I also know now why this will not work. Because the anaglyph goggs, or your eyes are placed in one fixed ratio, any other image will not siphon out the image of anything more different than that distance. Therefore, my theories of making anaglyph images to show how a rabbit, an eagle or a deer looks have all been unfounded. Damn.

However, I tried to make a real anaglyph next. What troubles you is the coloration of the hightones and the shadows. Should cyan also mean coloring it green and blue? I have no idea. Blue is a common factor in both magenta and cyan. This would explain why creating two images then fusing them together does not bring back the old image. Neither anaglyph component has anything yellow, so yellow gets filtered out in the processin itself.

I should have left that intact to give the picture some authenticity. Anyway, this is pretty good for a third attempt. Looks somewhat like an anaglyph, but still does not work. This is of a mouse.



I like the look crossed version of anaglyphs, which does not even require glasses.

My first introduction to anaglyphs were the august 1998 issue of National geographic. It had beautiful ones of the Martian landscape as well as ones of the titanic exploration. Amazingly enough, atleast the ones of the Mars exploration have somehow managed to find their way into wikipedia. Click here

another cool way to make anaglyphs keeping in mind the fact that you have only one image to start with, is to expand one side, and contract the other using paint or photoshop, then color-toning them in photoshop to get ther equired result. The principle is to slightly doctor the image so that it appears that you are looking at it from slightly different angles.
