Found a guy on instagram who builds a custom stereoscopic camera with 4 identical pi cams spaced evenly (about 1 inch (2.54cm)) away from each other on a line. It creates wigglegrams

I’ll shill a library I wrote to make wigglegrams & stereograms in matplotlib - I think pseudo-3D visualization is super underrated as a technique to understand data!

I agree. The first three from reddit work really well for me. I assume it's because of the fixed horizontal movement, and the fact that they are captured at the same moment from different angles. :)
The others are nice (but hectic) animations to me.
Same. I have amblyopia and I'm really appreciating the effect. I think people's brain with "only one" eye rely a lot more onto perceptive and parallax effect for 3D perception.
That was fun, and the script on github looks hand-written which is refreshing after having been reading AI-written code for months.
I have 120k photos in iCloud that I'm sure have duplicates (I exported my library to Google Photos years ago and exported it back to iCloud). The iOS duplicate detection stopped flagging duplicates for me to merge a while back. I gotta do something like this script...
I've noticed that GIFS with several frames in them tend to be quite large files. I like that these use dithering, which can reduce the file size. Ideally it would be not larger than 2-3 lightweight photos juxtaposed together, and less than 300KB. I also wish there was a pause button on them because sometimes reading articles on the web with them persistent can get tedious. I suppose disabling images can mediate that, or copying the text to another document.
"In Web Browsers (Chrome, Edge, Firefox): Install browser extensions like GIF Scrubber on Chrome or GIF Blocker on Firefox, which add playback controls to any web page.
On iPhone/iPad: Go to Settings > Accessibility > Motion, and turn off Animated Images to pause all GIFs in Safari.
On Mac: Go to System Settings > Accessibility > Display, and toggle off Animated Images.
In PowerPoint: Press the 1 key on your keyboard during a presentation to pause the GIF."
"Yes, but not natively just by using a standard <img> tag in web browsers. Because native APNGs play continuously like a traditional GIF, you need to use one of the following methods to pause them: [1, 2, 3, 4]
1. The Canvas Method (Best for Web Controls)
To add play/pause functionality, you cannot use an <img> tag. Instead, you need to render the APNG onto an HTML <canvas> element and control it using a JavaScript library like apng-js. This provides precise, video-like control over the frames. [1, 2, 3, 4]
2. The Cover Method (Simplest Fallback)
If you just want to freeze an APNG on its first frame, you can layer a static .png of the first frame directly over the APNG. When you uncover or hide the static image, the underlying APNG will be revealed and play as normal. [1]
3. Use CSS Animation Alternatives [1]
If you are designing the animation yourself, an alternative is to build it as a single static image (a filmstrip of all frames side-by-side) and animate it using CSS background-position. This allows you to pause the image natively using the CSS animation-play-state property. [1, 2, 3]"
On my Pixel phone I always leave enable the "Top Shot" setting, it saves a short low resolution video clip in the XMP/RDF metadata of the JPEG file. It saves motions that are not visible on a still image adding valuable information. iPhones and Samsungs have similar settings.
I often take a very short video, under 5s, rather than a picture. Even 1-2 seconds captures dimension and sound in a different way than a still picture. I’ve had people say it’s strange but they work well for me.
Live photos on iOS are exactly that, by default, each time you take a picture, it embeds the 3 seconds before the shot and the 3 seconds after the shot as video with sound.
It looks like a useless feature on the moment because what you want is the nice framing you are trying to capture, but it happens to become an incredible feature years later when a long press on your photo makes your then baby smile and laugh.
It's a best of both world implementation because unlike just capturing a video, you still get your high quality, stabilized and sharp picture of the picture you capture PLUS the video.
If you have an iPhone, it does this automatically (provided you don't disable Live Photos). Quite fun to review all the random stereoscopy you have inadvertently created by having an unsteady grip on the camera...
I had a look at the top submissions on the /r/wigglegrams subreddit [0]. It seems that some (including some of those featured in the article) are the more prototypical stereoscopic wigglegram, whereas others are more a stylistic effect.
It's tech from the 80s. Look up the Nishika N8000 and Nimslo 3D.
Basically it's multiple lenses next to each other, each capturing a small slice on the 35mm film. Every lens has it's own shutter, which is triggered at exactly the same time.
This wasn't too involved and quite cheap to implement with analog tech in the 80s/90s, but if you want to do the same thing with digital there's quite a bit more to consider. Here's a cool video of someone building a digital stereo camera: https://www.youtube.com/watch?v=_aofxbH0elo
The hard part with digital boils down to: Cheap camera modules are hard to calibrate to the same parameters and sometimes impossible to set focus, so pictures look the same. And taking pictures takes quite a bit of processing power, so if you want to take 4 pictures at once it gets a bit tricky with just a cheap raspberry or similar.
Ah, might have to try that. I've been getting adverts for "proper" versions of these (eg the Dispo Parallax) but no-one seems to sells them in a M4/3 mount (and I'm not keen on using adapters.)
To add to the other comments if you have the idea to use multiple camera to make the same effect but at a higher quality (and if you somehow sort how the synchronisation problem), then congrats ! You have invented bullet time, as demonstrated 27 years ago* in the Matrix.
I believe there have been camera specifically designed for this, where they have multiple horizontally spaced lenses that all take a picture at the same time, or literally just holding several cameras right next to each other and triggering them all at once
I have ADHD and normally excessive movement on my monitor disturbs me, but this didn't bring even a little discomfort. I didn't get addicted to them as well.

Somehow the extra motion seems to reduce the illusion of depth, it just seems like a disjointed animation to me.

Yeah, the first three work for me too. (just realized my original comment was kind of ambiguous)
The ones from Reddit also have more frames, I'm guessing they were taken on on a Nishika 3-D camera.
Intresting, I have a weak eye so rely less on stereo; these pop as much more 3d then a photo.

We really need a short for "is it AI or not? has entered the discussion".

There's been a move towards using MP4 files instead of GIFs because the filesize is smaller, despite MP4 being patent encumbered.
I found APNG suffer the same issue, but there may be some workarounds:

The website is really nicely designed, and the dithering on the images is quite beautiful.
Includes repo for finding pictures taken from slightly different perspectives in a photo archive, and making wigglegrams from them.

Not that strange I guess, given how iOS does that automatically for all taken pictures.
The same effect is used in a Dan Deacon video.

Haha that's excellent. Super fitting effect to go with his music
I made these in 2007 https://trondal.com/oygardstjonn

That link should have an epilepsy warning.
Contrary to popular belief, only a minority of people with epilepsy are sensitive to flashes of light.
Good idea, but the discovered image sequences are very different from the deliberately created examples at the top of the page.

If you're using an iPhone, couldn't you automate this by extracting "Live images" which are kind of "mini-videos" around the photo you took?
I think the title is missing a verb ...
I think I accidentally a verb.
It's a meme.
Doubles as a motion sickness test :)
How is the first one done? It seems like the cartons would fall faster than you could manually capture 2-3 images?
(super cool all around, thanks for sharing)

This is one option, trading ease of use and low cost for lower picture quality and less light.

*ouch, I feel old
>if you somehow sort how the synchronisation problem
These days you can just capture video and make a 4d Gaussian splat
> ouch, I feel old
Inside of every old man, is a young man, going ”What the hell just happened?”.
I believe there have been camera specifically designed for this, where they have multiple horizontally spaced lenses that all take a picture at the same time, or literally just holding several cameras right next to each other and triggering them all at once
I assume more than a single camera or a moving camera with a very high shutter speed with fixed focus.
really cool. I imagine this will land as a filter on insta soon :D
I imagine those to be like crack cocaine for people with ADHD, but I just feel like I'm being zapped watching them.
I have ADHD and normally excessive movement on my monitor disturbs me, but this didn't bring even a little discomfort. I didn't get addicted to them as well.
I am diagnosed with ADHD and the amount of jumping movement in these is torturous.
It did nothing for me
Awesome
