It seems like it would be simple enough to convert a video into an image like these by isolating a single column of pixels from each frame and putting them together chronologically.

Yeah, that was fun: #starting at 467s and outputting the images of the next 3 seconds ffmpeg -ss 467 -t 3 -i video.mkv output.%04d.png # crop image to 1px slices 280 pixels from the left. gm mogrify -crop 1x+280+0 *.png # stitch them gm montage -border 0 -geometry +0+0 -tile x1 *.png image.jpg Perfect example how easy and straightforward it is to use command line utilities. Now someone just has to find movies with st…

Cool hack! I learn something new today.

As many others have mentioned, this is a well-explored field. Golan Levin maintains a very extensive list of slit-scan camera experiments, check it out for some awesome examples: http://www.flong.com/texts/lists/slit_scan/

This pic [1] always used to bug me. Finally makes sense.

You don't need an $85,000 camera to play around with slit scan photography. As with just about everything these days, there's an app for that: https://itunes.apple.com/us/app/slit-scan-camera/id419292360... Note that this is slit-SCAN, which is a bit different in that it moves the "slit" across the face off the sensor, rather than capturing from a static slit over time (the same technique was used in Star Trek:TNG to…

If you want to play with real hardware, scrap a $100 scanner. Simplest/oldest: http://www.sentex.net/~mwandel/tech/scanner.html (The garage door picture continues to be awesome after so many years.) More professional version: http://golembewski.awardspace.com/index.html (And weirdest - you really do not want to blink during one of these photos.)

There's also the (admittedly more expensive) wonderful Widelux camera and its various Russian knockoff models. Jeff Bridges uses it to wonderful effect to document on-scenes at most of his movies, and then present the staff with a book when shooting closes. http://www.jeffbridges.com/camera.html

Look up "The Fourth Dimension" movie by Zbigniew Rybczynski - at first sight it is hard to believe it was made in 1988 because it looks like a product of some heavy digital 3D processing. In fact it is each of the 625 horizontal scan lines shifted a bit in time relative to the previous one, an idea very similar to the one described in the article.

Here's the first place I saw this in video form: http://www.mutek.org/en/tv/191-biosphere-genkai-1

CINECHAMBER CHANNEL BIOSPHERE - GENKAI-1 Official video by Egbert Mittelstädt From the album N-Plants

It's performed in the cinechamber which is four huge video walls with I think an eight speaker array. The time distortion is amazing and you are totally immersed.

In fact I hacked a Perl script to make slit scan video (which is a trivial step in digital).

Some examples:

I built a camera like that out of wood a couple years ago. It uses gears on the inside to pull a regular roll of film through and expose it through a narrow vertical slit as you rotate the whole camera on its center axis. It's sort of a broad-stroke photo. http://nnife.com/d/?dimension=33 Here are a few shots that turned out decently: http://nnife.com/p/?dimension=20 These are just film scans. You can by the light ba…

I recently discovered that you can get some interesting results by pointing the iOS6 panorama camera out the window of moving vehicles...
