Apologies!! I posted this in entirely the wrong place. This issue is directed at "StereoPhoto Maker". I can't find a delete so I'll just make this edit and change the body to reflect StereoPhoto Maker instead of StereoEditor. The question still stands, but the mods can feel free to delete this thread..

Hello everyone,

I'm using the StereoPhoto Maker program and getting great success creating stereoscopic images with my own photos. My question is how can I be sure my results are correct for standard 3D displays? I have had no problems viewing my creations with the internal StereoPhoto Maker viewer, I play slideshows and every image is correctly aligned and displayed. However when I view my JPS images in other programs I find that I have to use the "Swap Eyes" feature with some images, but not with others. I'm a little confused.

Hello;

Thanks for pointing the forum issue, we created an appropriate forum.

Stereo 3D standards are not very well known up to this point, and there's a bit of confusion in software.

Let me ellaborate: JPS images are supposed to contain 2 JPGs side-by-side: the RIGHT image to the LEFT and the LEFT image to the RIGHT. Why is that? because if you open the JPS in a regular photo viewer it's possible to use the crossed-eyes technique to view stereo 3D.

From ephehm.com/jps/

Q) How do I make JPS files?

A) If you already have stereo pair pictures, you're almost there. If you don't, there are several good tutorials out on the Internet on how to produce them photographically or in a program that you can use to render 3D drawings.

Once you have your stereo pair, you need to combine the two images into a single JPG file. It's best if you keep the files in some lossless format like TIFF, PNG or BMP while you are working on them and convert them to JPG at the very end.

Open your bitmap editor, almost any will do. Create a new drawing that is as tall as your pictures and twice as wide. Import the right eye image and paste it on the left side. Paste your left eye image on the right side. Save the resultant image. Rename it with a JPS extension and you have it. Open your file up in a JPS viewer and admire your handiwork.


Some programs open the JPS image and swap their sides again, producing incorrect results.

Fortunately, it's not too difficult to fix: you can either swap sides or save the picture with swapped sides (which is bad because it kills the crossed-eyes technique).
