Hello

Does anyone have experiece producing stereographic photographs with a 4x5 camera?

I'm researching a fine art project that involves producing anaglyph prints printed and framed at 4'x5'. There seems to be no shortage of 35mm based cameras, DIY resources, and accessories such as slide/parallel camera mounts. But, I haven't found anything about anaglyphs shot on LF, despite the abundance of 3D commercial work and films, not to mention NASA and National Geographic...

To provide a little more info on my proposed workflow, i'll be shooting in a studio environment, drum scanning the transparencies, then ideally sending the files to a reputable professional 3D studio for processing before printing via lightjet.

If anyone has any experience or thoughts on the matter, I'd appreciate your input.

Thanks in advance,
Mark

I'm into stereo (3D) photography but not into anyglygh per se. There any number of forums at yahoo groups that deal with 3D and anaglygh specifically. I don't have any short cuts handy but they are easy to find at yahoo groups. You should find what you need there.

I would use two mirrors to achieve eye-width spacing. The mirrors would be eye-width apart and reflect the image at a 90-degree angle to the camera lenses.

(Hmmm, have to try that for myself!)

Every so often you see an odd arrangemnt show up on eBay. This is a a pair of lenses mounted on a Graphic 4"X 5" lensboard with a Packard shutter in the rear. It may or may not come with a "splitter" to keep the images separate. Whether the original idea was for ID or stereo I don't know, but obviously would serve for stereo.

FWIW, most of those old (Civil War Era) stereo cameras were about 5x7" or some more exact number close. Once I discovered stereo, a mere 2D image seems flat (pun intended). :D

I found this site (http://www.instructables.com/id/EPTUHNQHR2EP287AG7/) with instructions on how to make a anaglyph adapter for a camera. Mouse over the pictures at the top for an overview, and then click them for instructions. Should be adaptable for 4x5.

hmmm.... thanks for the link brian - sounds quite interesting, and simple enough to have a go without feeling like you put all your eggs in one basket...

does anyone have any thoughts on these heavy-duty slide bars by chance? i'll have to get in touch with them to see how well they accomodate a field camera:

i'm quite curious how they shot that recent 3D sports illustrated swimsuit issue :p

The slide bars are pretty heavy duty to be sure, whether or not for a 4x5 remains to be seen. Send them an e-mail and ask. Both of your bar sources are good, but the first one I have delt with numerous times, cool guy, his name is Steve Berezin. A very approachable person and will help with your ideas.

As for the swimsuit issue, probably with a pair of Canons. There was an article in a stereo magazine ("Stereoscopy" put out by the ISU , International Stereoscopic Union http://www.isu3d.org/) about a sports photographer who specializes in 3D, his name escapes me for the moment but some of his set ups he ultilizes $100k in lighting, could have been done by him.

As a follow up to my previous post, the photographer's name is David E. Klutho that does 3D sports photography. Incredible images and 3D to boot.

With their tongues hanging out! :eek:

As to the bars, if the weight of your 4x5 and lens is six pounds or lighter, I'm sure it would work fine. My Pentax 6x7 is about that weight, and so is my Graflex Super Graphic. My Calumet 4x5 is 10 pounds.

Do a web search on "close range photogrammetry". I've been away from the business for a number of years, but I do recall that one company made a heavy duty bar to hold 10"x10" cameras at the correct distance. Rollei, Hasselbald, Wild, Kern, and Zeiss are some of the companies that build things that might work. Don't use the photogrammety cameras though - unless you want grid lines (like NASA moon walks) in your image.

Also, contact http://asprs.org and see if one of their advertisers or members will lease the equipment to you.
