3D growth... (and I dont mean poser)

Hey
Umm I want to try something, but I need to know something first...

which works better for you people the red-blue 3D glasses or the eye-cross style of 3D?

Not everyone has glasses, but then not everyone can do the eye-crosses either.

just curious because it dictates how I shoot things, and which camera I use.

gee... what could I possibly have planned......

cross eye, I cant stand red/blue.

Cross Eye. Unless somebody knows where I can buy Red/Blue glasses...

Agreed, since those glasses are a pain to come by. So DOES anyone know how to get a pair or two?

There's a few movies out there that come with them. Spy Kids 3, Nightmare on Elm Street multipack, etc.

Having said that, red/blue 3D sucks. Those gray polarized 3D glasses like you see in some 3D motion theater rides (Terminator 3D at Universal Studios, for instance) are the best. However, they're even harder to come by, so your best bet is probably the eye-cross thing.

OK Cross eye it is...

this should be an interesting project.... lots of math.

I pick red/blue, because I can't cross my eyes. Believe me, I've tried.

I, too, cannot cross my eyes, but this "cross-eyed thing" is easy when you get the general notion behind it.

Try this as an exercise. Get a pencil, pen (or otherwise long thin object) and hold it in front of you. However, don't look at the pencil -- look /past/ the pencil, but keep the pencil in view. You'll notice that the pencil has split into two.

Now focus on the pencil. The background will split into two. Now focus back on the background. The pencil will split back into two.

Now get two pencils and hold them side by side (left and right). Focus on the background until both pencils meet in the middle creating a third pencil.

This is the general concept. Stereograms operate under that same principle. If you look at the design of all stereograms, you'll notice that it's a tiled texture, with squares that repeat over and over again from left to right, top to bottom, and that each tile, while mostly similar, will be somewhat different. This is the 3D image.

Now, doing the same thing you did with your pencils, cause the repeating squares to come together (as with the two pencils), pushing two of the squares into a single third square. Keep your eyes like that until you'll see something pop out.

Personally, I don't like stereograms because they only work if you concentrate and you don't get color. It's 3D, yes, but the entire object is in the same texture as the stereogram, so using it for things like humans (or similar) might not be the best idea.

Of course, that's my opinion. :-)

I think you're confused with the 3D posters with the ugly textures that they'd sell in the 90s. (like in the movie Mallrats.. its a sailboat!)

I believe Xil is talking about stereoscopic images like the one I'm attaching below.

2 normal photographs side-by-side, each with a slightly different angle. When you cross your eyes, a 3rd image appears between the two, and is in perfect 3D! The effect is pretty damned good.

This image is from http://www.stereoscopy.com/gallery/index.html , They've got quite a few images there, check em out.

I always seem to get better results from the "parallel viewing" images than the cross-eye there. The cross-eye images there always give me a bit of shimmering, but the parallel are always rock solid for me. But maybe that's just me.

Yep I am talking about the stereocopy images... infact I have that very link bookmarked.

I am shooting with a model tomorrow (a test shoot, nothing is expected from it) and I will see if she my 3Dgrowth model for the future set.

the only thing I have to figure out is the scaling math involved, should be interesting to try. If I can get things to work right and if it sells enough to cover I will do more.

Of course if anyone knows the actual ratios needed, PM me. it will save experimentation.

Wish I could help, but I know very little. I assumed it required a special camera with 2 lenses. Or 2 side-by-side cameras rigged to go off at the same time.

This could turn out really great, especially if you could photograph pieces of cloth in midair as if they were "shredded off". With the depth of 3D, it would be stunning.

Good luck!
