Nice! Whenever I see rolling shutter photos on flickr/etc I always think about this old page where a fellow built a long-distance camera from a flatbed scanner to get the effect intentionally: http://www.sentex.net/~mwandel/tech/scanner.html

(There's a great image of a garage door opening & closing about 2/3 of the way down the page if you don't feel like reading the whole thing.)

This is so fascinating. This makes me long for the days when browsing somebody's homepage on the web felt like they were actually inviting you into their home like a friend.

His woodworking videos are fantastic. Also, FWIW, he's now got a whole page about the cameras he's used to film them:

You bet. Sometimes I feel a lot of these homepages were lost to page ranks and our quest to search everything on Google.

Same here. I love reading the pages of these super-creative types of people.

I did the same, as many other did:

That website was of some inspiration, great too see it's still online!

Fellow scannercam hobbyist checking in! Did you also discover the trick of taking "HDR" photographs by setting the software to do a "colour" scan with every colour channel set to a different exposure?

Anyway, in my case the hobby led me down the rabbit hole of slitscanning and other spacetime-warping artworks, such as Bill Spinhoven's "It's About Time" (who was one of my tutors in art school, and AFAIK was the first artist to do this in a real-time installation)

These day's it's quite easy to do with software. Here's a test of one of my own prototypes made with Processing:

I went down this rabbit hole myself, it's great fun. On our camera we noticed The RGB sensor data lined up well moving right-to-left, but misaligned when scanning left-to-right, creating a subtle rainbow effect.

Wow, that's great! Thanks for the links!

Cool!

It reminds me of the slitscan special effects technique that was used to create the stargate sequence at the end of 2001: A Space Odyssey.

Conveniently available as a really cool iPhone app:

I'm a big fan of this because (a) it gives you a photo with a time dimension! and (b) it happens to be a similar technique to what some satellites use (a single row of pixels that sweeps across the sky) so it's cool to gain an intuition into how that works.
