This is really cool!
Re: There oughta be a bullet time video booth
#23Seems a good place to ask: anyone know a good tutorial for building your own diy photo booth?
I quite like this one. It's crafty and cute https://hackaday.com/2019/12/22/build-a-dslr-photo-booth-the..., though there's no printing.
It's not abundantly hard to bang together something functional, really. It's one of those projects where you just think about the components you have (Camera, Monitor), and then make an enclosure (or find 3d/laser files), then some code that's surely on github to sync them together.

#24I'm usually a big critic of AI, and I remember seeing people complaining years ago about increasing framerates with AI[0], but maybe this could be a good usecase. You do, say, half the cameras, and then some crafty solution to interpolate (filling in the edges with AI, some sort of angle adjust)
Re: There oughta be a bullet time video booth
#25Nice, but aren't the cameras supposed to be triggered in sequence instead of all at once? I thought there was still a little bit of motion in the movies, but in these the subjects all freeze in place.
One would think the cameras all record at the same time and you can just pan around and adjust speed whenever?
In theory the idea also enables a higher frame rate than that of which the cameras are individually capable, thus allowing a finer slow motion effect.

#26That camera had an MSRP of $899 when it was new in 2006 [0]. Amazing that they now sell for only £50, and still take fantastic pictures even by today's standards [1]. Technological progress is nothing short of remarkable. [0] https://kenrockwell.com/canon/rebel-xti.htm [1] https://onfotolife.com/camera_sample_photos?camera_id=30&pag...
It is a great moment for people that want to get into photography, because the market is moving to mirrorless but there's plenty of old high end DSLR gear that people are getting rid of but that can produce excellent pictures. The important part of the gear is the lenses, and those can be had used for a fraction of the cost of new ones. For the bodies, the sensor quality has consistently improved over the years, but the quality of 35mm at ISO 100 has been matched and surpassed a long time ago. As a first approximation, you can say that about 10 Megapixels are enough to match film[1]. Subjectively you could say that digital matches and exceeds film since around the mid-2000s.[2] Anything newer than the D2 will be more than enough for any hobbyist. The subsets of photography that benefit from the improvements of the past two decades are low light photography (birding), sports (if you can shoot 9fps and the pal next to you can shoot 11fps, they are the ones more likely to get paid for the picture) and videography (both due to quality of the recorded video as well as ease of use, like better auto-focus).

The project already used frame interpolation (through DaVinci Resolve) to double the number of frames in the video. Plus a low-tech "inside the wall" panned and blurred frame. Given the set-up, fancier scene reconstruction to build a 3D model of the environment could be combined with texture reprojection to improve the interpolation and allow the "inside the wall" frame to be perspective corrected, but that would be much more involved on the software side than what was done here (and beyond what I could do too).

The tech to look out for in this space is called NeRF (Neural Radiance Fields).
Just do a quick search on that term and you will find a whole bunch of videos that reconstruct 3d scenes using digital stills. I just saw a paper a couple of days ago showing advances in reconstructing human expressions that change over time using advanced techniques.
Re: There oughta be a bullet time video booth
#29This is a bonkers idea! I fucking love it, man! I bet I could do this with a single device on a rail and use NeRFs to actually make the effect. Could even do more complex camera flight. Love the idea.

That's true if you want them to move slowly like in the movie. But to just freeze them you need to take all the pictures at the same time
