Is it possible to add support for 3D images. both JPS and MPO files. both format encapsulate jpeg files. I join an example file for both regards Eric Bayard

That you for this suggestion. ExifTool already supports .MPO images, but I will look into adding JPS support. - Phil

Great!!! I think a jps file is a jpeg file with both images next to each other. And maybe some extra metadata? Indeed if you change .jps into .jpeg then you can see the preview in the explorer.

The only JPS documentation I can find is for a 1997 VRex JPS format, which I don't think is applicable here. The JPS file you sent is basically a standard JPEG image with the stereo pair encoded side-by-side in the main image, and ExifTool will extract all metadata as a standard JPEG. The only unknown data is a 1692-byte trailer, but I am not convinced that this contains any stereoscopic information. The Wikipedia JPEG_Stereo article has been deleted as of April, so I can't get any information there. If you know of a reference to the JPS format, please let me know. - Phil

Hi, I suppose you found the same doc as me : http://www.vrex.com/developer/sterdesc.pdf Anyone else speaking about JPS say they are just 2 jpeg side by side. So I wouldn't worry to much about the unknown data, as long as it is kept in the edited file just in case. I can ask LG who is the manufacturer for my phone (from which the photo comes) about it if you wish. I also found this website : http://ephehm.com/jps/ that explain that verx products add an extra chunk of data to jps files that is not to be seen in usual other jps files, but that is requiered by verx product to open the file, could it be the data you are speaking about?

This is what I suspected. It sounds like there is no additional metadata in JPS images. If so, ExifTool already supports these files for all purposes except that it won't process them automatically when scanning a directory unless "-ext jps" is specified on the command line. - Phil
