I love the small insights into signal theory/processing generated by this image, this is really cool stuff! Thank you for chiming in.

Of course there’s some ancient broadcast standard at the bottom of 44.1khz, thanks for the clarification! (I work in film/TV and still struggle with explaining explaining ‘illegal’ values to some clients on certain deliverables)

I haven’t really considered that, I’m assuming the (in this case) vertical sampling is ‘global’, as in the values at each sensor site is locked at the same time and then read out from the serial bus.

If there was a delay, stuff like fluorescent lighting would read as a moire pattern, but I’ve only ever encountered streaking/linear distortion in those circumstances.

I think the ‘griddyness’ or general sense of direction in the water is purely a function of how water moves and not a result of readout delay.

I’d love to be proven wrong, though, so if I can do some experiment to determine either way, I’m all ears.

Thanks! I’d love to hear your thoughts if you feel like sharing.

Thanks! Your nitpicking is most welcome.

Thanks, I agree, it’s one of my favorite shots from this camera.

That’s pretty clever. You’re walking in the footsteps of the Dutch masters, using projection in this way. I really like the drawings, and congratulations on finding more uses for your device!

I case you’re really wondering, the model has two legs, maybe three, the liquid effect is due to the very slow rolling shutter of the scanner, and how it draws motion.

And why is there a face just floating in mid-air?

For sure!

I opened up an old Canon flatbed scanner and more or less removed anything that wasn’t the sensor or the mechanical assembly pulling it along. The optical assembly is hacked together with black foam board, an acrylic magnifying glass and too much gaffers tape.

Think of it as a pinhole shoebox camera with a scanner at the back, instead of photo paper or film.

A really good boy, and that’s what matters, thanks for the BTS shot.

When rolling shutter is the main event, better make it look good, right?

I have a series of shots with the fabric, it’s the centerpiece of all of them, in that case it helps a lot!

Since I built the camera, I’ve been looking for ways to use its artifacts and idiosyncrasies to make pictures no one has ever seen, the temporal skew that it allows is super interesting to me.
