Pentax stereo

Not as convenientas the set at the top of this post of Womble's, but I refer you gentlemen to my image in the Galleryof last week, showing two images of an aquilegia flower.
These/this was taken to be viewed using the "cross-eyed" method. It takes a little practise
But, once mastered, the 3D effect is remarkable.
The image was taken with a k5 & 100mm macro. The camera on a long mounting plate to enable a "separation" of 66 mm.
The website revered to above (with Queen), has details.
There are many superb (extreme macro) examples on the photomacrography website


Roger.

Changing the subject slightly, one other classic 3D stereo promotion was by Weetabix who put paired sets of images in their cereal packs. You had to purchase the bright red folding viewer (for half a crown I seem to recall). For a freebe they were fantastic quality.

Yes, I remember those too.
There's photos of the viewer and image pairs on Brian May's site here:

Apparent;y the viewer was actually just 1/6 (that's 7½p converted.)

There's an amazing number of image cards for sale on eBay and even a viewer:

I noticed on ebay that the box that a 3D Coronet camera had been posted in said 'from Quaker Oats' so they must have either sold them or given them as prizes.

Also on ebay are some slide viewers that take two normal slides. They would be very useful for 3D slides taken using focusing rails.

You could even stick two standard slide viewers together.

I've discovered this strand after a very interesting if slightly bizzarre conversation with a Punch and Judy man at the Black Country Living Museum, which seems likely to lead me to get out my stereo kit and fit it to the front of my Sony Alpha 7. I shall then need to find a way to view prints. (It won't fit onto my Pentax, which is a 67!)

One bridge at a time...

An easy way to view any large photo as STEREO is to go fairly close..... hold your left hand cupped over your open left eye and the right eye supplies the image the brain should fill in missing stereo details.

The photo is not 3D just normal and usually colour. Try switching eyes if it doesn't work. Won't work if you haven't got a brain.

There's some more info here about the Optio RS: https://www.ephotozine.com/article/stereo-photography-with-the-pentax-optio-4803

I have a Pentax K50 and a stereo converter. I also have a 3D W3 camera to produce 3d images. I use software STPHMKR to process and edit the results. To view them I used to print them out side by side and view through antique viewers from Ebay. Then I found Brian May's site, London Stereo, and bought an Owl Viewer. I put my side by side photos onto my old Amazon Tab (6 inch I think). And now I have perfect stereo photos that I can carry around to show friends without the hassle of paper prints which are both expensive to print and easily. Does anyone else have tips on stereo activity? My history in 3D goes back to the mid 1960's when I bought my first Viewmaster camera, film cutter, and stacks of blank reels. Still got everything but slide film now a bit too expensive for an amateur like me.
