In the old days I used an old theater beam splitter, Tamron 90 macro lens and did slides. These were projected using the same beam splitter (now transferred to a slide projector) and projected using crossed polarizers and crossed polarized glasses.... It was fun for awhile but the subjects I liked needed hypo stereo and though I could tilt the mirrors it gave a tough to reconcile background. Below is one of these files, scanned in for printing (though this of course is a reduced file).
Pentax does (or did) make a beam splitter to attach to a 50mm lens (others as well but it was designed for a 50).
your easiest way is to take the two images, make a NEW image twice as big as 1. Copy and paste them side by side on the new sheet.. Adobe or Corel or any number of photo editors should easily allow this.

Jeff,

I have the Pentax splitter (havn't used it in a decade or more) and really did enjoy using it when relevant. I sat back from the screen and looked at your images and was able to parallax fuse it into an onscreen 3D image. Looks fantastic.

Thank you.
Your convincing me to try and get my Minolta slide scanner to function again... POS never made the transition to XP. Not to mention some off standard SCSI cable ect... Ahhh the good bad old days........

low this.

Borrowed this image: I may have to buy one of those loreo Macro attachments...

Unfortunately I'm not real crazy about the sharpness of a single plastic lens for $120.......

That's my feling about the Loreo. Pentax make the Pentax Stereo Adaptor D which I believe is available for about $AU189. Compare the price for the quality with Loreo "plastic" and its a no brainer, as they say. Looking forward to getting mine!

Pentax stereo adapter has been on my "wish list" for 15 years...... Unfortunately it's baseline is not really the best for Macro work...
Here's a picture of MY monster, next to my super program ...
Loreo doesn't require a lens though...... Might have to design my own.......

Mmmm - its a bit of a lump. The side view shows knobs or screws that look twiddleable. Are these for adjusting the mirror angles? I should imagine this is a feature not available in the Loreo or Pentax gadgets. Under what conditions would you change the mirror angles? Sadly my grandfather is long gone and I cannot delve into his years of experience. Being a silly kid at the time i was not sufficiently interested to pay full attention but his passion in later years was close up flower pgotography (stereo, of course) specialising in wildflowers. I seem to remember he had his camera on a base which allowed him to measure the separation and angle very accurately. The results were often stunning and he sent them around the world sharing them with other members of the Stereoscopic Society. I have a small sample of some of his work. Its something I would to explore. How wonderful digital is that I can click away and experiment and immediately view the results, without having to wait a fortnight for the expensive slides to be returned in the mail. However, i don't think it will make a photogrepher of me. I remember a National Geo photo article a few years ago where the bloke went into the wilds for a month with a single roll of film to take one photo a day. The results made me weep! Now THAT'S a photographer! Please excuse my ramble. It's nice to have a chat.....

This was built to be used on a theater projector, so the angle adjustment was more for getting the image in the correct position on the screen (was actually attached to the projector lens in an up/down position, not right left) The front metal clips held polarizers that were crossed to each other (if you put them together you would get zero (really close to zero) light transmission.
I used it to effectively shorten the baseline for macro work. The side mirrors floated (big spring thing in the middle) and there were 2 small allen screws used to adjust the position of one side. Big knob was to adjust the main angles to converge the 2 images. Nice this about this is I had it set up to take the picture and then could us it to project the picture from a slide projector. Using a silver lenticular screen, crossed polarizers and some home made crossed polarizer glasses and you had a 3d slide show......... Sounds more complicated then it was.........

stuff like that always puts me in my place.......

Thanks for the explanation of your equipment. I'm wondering if I could create something from an old set of binoculars.............Just as an exercise ,of course, I'm still hankering for the Pentax attachment.

That's exactly how my Grandfather showed his slides in village halls etc. I remember the gasps of awe as each slide was shown and almost a feeling of vertigo as if you might fall into the giant trumpet of a daffodil as it jutted forward off the screen into the 'audience' or the texture of the inside of a forget-me-not flower projected 6feet wide. I've never come across a mention of such a thing in Australia (been here 32 years) I think it might do quite well.
