Now in 3-D

Seems like I'm riding a wave of gimmickry lately, enabling the inner colorcasters ("Throw off your bichrome shackles and follow me!") and many apologies to your spouses/significant others/parents for making your kitchens smell like burnt wax. I promise not to let my novelty ADD cause too many more domestic problems.

Say "cheesecheese" A few you you might remember my last ill-fated attempt at budget 3-D photography. If you've mercifully forgotten, it looked like this. The results were exactly what you would expect from two dollar-store cameras held together by packing type and cardboard scavenged from the copy room. Let's say they were less than stellar and move on.

3-D photography (technically stereo photography) has been around for decades, it's not a new trick, and you can even fake it by taking two pictures, sliding your camera horizontally a bit between shots. There were a lot of dedicated cameras built over the years, some which would even let you prepare your own View-Master slides. Pretty cool stuff, but being collectible, this sort of camera is one of those would-be-nice-to-have-but-not-at-that-price items.

Well, it looks like Fuji is trying to reinstate 3-D photography again, giving it a 21st century kick in the pants with a new dual-lens digital camera that sports an tehnobabble-laden set of diagrams illustrating exactly how this will work. It's all very fancy and impressive, and one of the points they're touting is the use of "a fine pitch lenticular sheet" over printed photos to give you the 3-D effect without glasses or a viewer or doing some kind of crossed-eye technique. You know what lenticular sheets are: remember those little rulers we'd have as kids that had pinwheels printed on them, and as you tilted the ruler, the wheel would appear to turn? (Hey, it was the 70's.) That bumpy, clear plastic surface was the lenticular lens, which showed you different views of the underlying image. There's software and products out there that will even let you do this yourself.

What Fuji fails to mention, though, is that lenticular 3-D photography is nothing new, either. Behold!

Nishika N8000 3-D 35mm camera

This monster is a Nishika N8000 camera, which takes four half-frame photos on 35mm film. (It's also freaking huge, and I'm been informed that it's "totally pimp style" whatever that might mean.) Despite all the high-tech appearance, this is just a basic, mostly-plastic fixed-focus camera. You can follow the article links on Camerapedia to find out more about its history. Nishika would offer lenticular printing of your cherished photos of... whatever you decided needed the winky-blinky 3-D treatment. Nishika's gone now, but of course there's a small group on flickr of folks who use it and scan the results, assembling them into animated images that trick your eyes and brain into figuring out the 3-D scene. This one is one of my favorites right now since it demonstrates the advantage of a multi-lens camera: taking photos of something in motion.

I loaded up my Nishika this morning for the walk with the dog and took some photos around the neighborhood. I don't want to befuddle the Walgreens clerk with a roll of seemingly identical half-frame shots, so this is going to be another Caffenol roll. I'll let you know how they turn out. With four lenses, this should be twice as much fun as that jazzy new Fuji, right? Besides, Nishika even bothered to put together this painfully earnest and horribly cheesy instructional video starring the late, great Vincent Price:

The $2 Stereo

I was digging around the old cardboard box that serves as the tattered remains of my baby scrapbook (before the golden age of acid-free paper, sadly) and I found something that I thought had gone missing: my grandfather's old stereo photo viewer, and some cards that he and my dad shot over the years. Stereo photograpy eventually morphed into the Viewmaster, but there's still a quite active group of people who shoot this way. Since true stereo cameras are sadly priced out of my budget, I started wondering about ways to DIY.

The problem boils down to taking two photos side by side, usually done by snapping one photo, and then moving the camera laterally a few inches and taking another. Lay the photos side by side, cross your eyes, and you should be able to see the result in 3-D. The modern solution now seems to be to strap or otherwise connect two inexpensive digital cameras side by side and take the photos, sometimes even with a custom rig to press the shutter release at the same time. This last aspect is actually key: if you're trying to take a 3-D picture of something in motion, the lapse between side-to-side photos is enough to make a "shiny" spot on the combined image as your brain tries to resolve the conflicting images from each eye. Better to take a still subject on an evenly-lit day. My grandfather fashioned a simple platform for his tripod that he could use like a portable table, but lugging a tripod around is not exactly practical for a casual experiment.

Say "cheesecheese" I'd like to use my grandfather's viewer, though, if only because the eye-crossing thing makes my head hurt after a while. And I am, as you know, incredibly, incredibly cheap, far too cheap to actually buy two digital cameras from Walgreen's and Velcro them together. So here's my first experiment: the $2 stereo. Two disposable cameras from the dollar store, held together with tape and cardboard scavenged from the supply room. The distance between the lenses is slightly wide, but this will supposedly result in something called "hyper stereography" which results in a slightly exaggerated effect. For two dollars it's not worth fussing about. More worrisome is the large gap around the case of on of the cameras, which may let in light. I may wind up with a roll of lots of tree photos, and a roll of sunlight.

Simultaneous shutter release will be attempted by a clever mechanism known as "I have two hands, don't I?" I'm going to head out at lunch today and see what develops.

Post-lunch update: not surprisingly, one of the cameras crapped out after a couple of shots, but I dropped off the film anyway. If it works at all, I'll be inclined to try again with something more durable.
