This is a thread about rail related stereo photography. Stereo photography is where two photos are taken side by side at the same time for viewing using a stereoscope such as a View-Master.

So what information are you going to put in this thread for our edification?

Side point: My Dad had a View-Master stereoscope. It gave me hours of amusement as a child many decades ago. Not sure what use it would be these days however!

Well, how about some example of railway stereo photography?

You have to de-focus your eyes to see it.

I have never been able to see those things. Perhaps because the vision is completely different in each of my eyes: my right eye can see close up, my left distance.

@apw5910 - I also have never been able to see these nor, nor are the images on that page rail-related, I would think. I also have never been able to see these things.
Anyway, they are not examples of stereo photography, this is about pairs of railway photos taken using stereo cameras, has anyone here done this or does anyone here know others who have done that?

There were stereo cameras that could take pictures to mount in View-Master discs, they would be taken on 35mm film at a quarter of the size of a 35mm film frame and then cut out using some sort of cutter.

Yes, Lindsay Rickard (a driver at Puffing Billy) has many stereo photographs taken of steam trains around the world. I have seen one presentation, sitting in the audience at the LRRSA with the red and blue coloured glasses (well, plastic really) on. Very effective.  We would like him to do another, but it's a bit problematic now we meet on Zoom.

How about getting a digital 3D viewer? This is like a View-Master but you can plug in into you computer to view pictures in stereoscopic 3D. Such viewers are better for viewing such pairs of colour photos, and thus nearly all stereo photos taken recently.

Could anyone actually post such pairs of photos?

You brought the subject up, why don't you?

I don't have any, others may have them.

Not exactly sure what the original poster meant by stereo photography as I am aware of two types. One is military aerial images where the aircraft camera took overlapping images that were viewed by a special very elaborate stereo viewer to identify items of interest. Apparently the overlapping images showed more details than just a single image. I know others besides the military also use this system.

Another type is historical images such as the following using a special camera that apparently enabled details to show better. There used to a display at the Tweed Regional Museum in Murwillumbah using a special projector

The example in the link you provided is what I assumed Myrtone meant by digital photography.  Two photographs taken simulateously with two lenses and regular eyes-width apart. If you can look at the left  image with your left eye, and the right image with your right, then you will see the image in 3D. This is achieved in projected images by using a stereo project, with two lenses, and either polarising one image horizontally, and the other vertically, or by projecting one image through a red filter and the other green (or blue?). In both cases the viewers wear glases which filter out the image they are not meant to see in each eye. The combined image the viewer experiences is often quite remarkable!

I can see this type of stereo easily but I've never ever been able to see those single picture messy coloured rectangles.

I can remember occasionally seeing railfans, back in steam days, taking stereo photos with two identical cameras joined by both being joined to a flat bar using their tripod screwholes and a double cable release.

Stereo photos, or simply two cameras, one loaded with colour, the other with B&W flim? That was certainly common enough - I've seen one bloke with four cameras all mounted in a frame.

That's what they were for when I asked. But I wonder if they were spaced far enough apart to get a stereo effect looking at both images with the right viewer?

Stereo according to the ones I asked as I thought I would be an interesting thing to try. I've tried it with non-moving subjects, aka stations and landscapes, by taking 2 photos a small distance apart sequentially on the one camera. The separation distance isn't critical but the framing is. To view I put the 2 prints on a table and looked down to them adjusting position to get the best middle image. Interesting but what I wanted was 35mm slides to show on a projector so one photo per scene ruled.
