3D Photography - Can new tech make it more accessible?

In specialized video editing programs (Adobe Premiere, for example) you can make any combination of sound, music and subtitles you want. The result is complex slideshow in a video clip format, that is best made at a high resolution and should be compressed as little as possible.

Anaglyphs deteriorate as the level of image compression increases.

4K video clips run well on most modern phones.

That is a possibility. I have Final Cut Pro 7 and that would do a great job. The only thing I worry about is the size of the video file vs a Power Point presentation made from Stills. I can do a short video of about 10 slides and see how it goes. Thanks for suggestion.

The large 3D image provided by video projectors is very impressive, but even with video projectors there can be several issues related to the 3D signal source and the type of signal required by each projector.

VR and AR devices are the future.
Already exist or are to be launched VR and AR devices that benefit from dioptric correction for each eye, as well as manual IPD correction.
There are dedicated apps for viewing 3D photos and movies with VR/AR devices.

As per 3D Gunner's suggestion about trying video, I did!  I took 10 of the stereo cards I have of old Saint Augustine, FL and put them into iMovie. I also used Photoshop to crop all the slides to the photos were all the same size, 1920x1080 which is Standard HD format.  This way all the images would all be the same size horizontally. I found a place on the internet where I could get copyright free music and made a presentation that lasts one minute.

This is just a test to see how well it works and to get an idea of how big a video file it would be. This one minute presentation is 126.9MB. I uploaded the video test to YouTupe and then downloaded it to my iPad and iPhone. It works on both but it is best to use the iPad vertically or the images get too wide to see in the viewer.  This test really shows just how soft many of the old stereo pairs were. 4K wouldn't help at all, but with modern equipment and higher quality, 4k would look great.

I think this is getting closer to where technology can make 3D viewing easier, but most people will still need a viewer, unless it can be built into a phone case or the bigger tablet cover (so a viewer is always right at hand).   Well, that's what I have come up with so far!

Hi All - This is a repost from another forum, but it seems more at home here:

I want to find a way to share and view stereoscopic images online / using a smartphone. I've found 2 ways, one which requires a VR headset, and another which might require some software / coding skills.

Method 1: (conventional)

Displaying two images side by side on a smartphone display, and using a VR headset (playstation VR or google cardboard) to view them in 3D. I have done this. It looks amazing, but it's not very accessible unless you have a headset. If i get some interest i can share a few of my images...

Method 2:

Using software such as "facebook 360" to view 3D effect by tilting the display. This uses depth information from a 3D 'portrait mode' photo and the accelerometer built into your phone to animate the image to appear 3D.

I like this second option because it is much more accessible to the average person, though much harder to pull off. (facebook 3d image sharing it is currently only available for recent iphones as far as i can tell)

As I have only captured 2 photos per scene, I would need a way to get a depth map from the two images, perhaps using a neural network, in order to fill in the missing depth information and get a seamless transition between the 2 images. Alternatively I could take a short video instead of the 2 images.

Here is a video that explains 3D photos on facebook and ios:

Any ideas on how this could be done? Perhaps there's a community working on this.

You have absolutely better ways now as ProMa launched ProMa King Tablet glasses free 3D, size 10.8" very easy to carry and show to others of your 3D works and ProMa 3D Monitor MV, which is to show case your 3D works to the public without wearing glasses...... See here for details:
