Taken on a small group of Islands in the Oslo fjord, called Hvasser. A 15 meter peice of fabric playing in the wind, scanned right to left in 21 seconds. Got really lucky with the clouds this time, allowing a single beam of sunlight in as a highlight.
@Leavingoldhabits Hi again, I’ve started playing with an Arduino and a light sensor. At the moment all it can do is read the LED light source from the flatbed scanner during the calibration sequence, and record the results.
The N650U has three stages of calibration:
The next step will be to introduce some kind of timestamp for each moment of the recording. Then the hard bit will be to shine a light source onto the sensor so simulate a proper calibration.
I haven’t recorded the calibration on the LiDe 110 yet, but I will. I didn’t realize it when I modified it, but the book says it will scan at 2400x4800dpi which works out to over 550mp for an A4 scan, which dwarfs the 20mp of my mirrorless, lol.
That’s some impressive progress! I’m sorry I didn’t catch this update before now.
This makes me think it should be possible to use an arduino due (which has a proper DAC) to send a custom calibration when the scanner expects it. It might even be feasible to add a transistor to the ground path of the LED, let it do the calibration, and disable during scanning. Could maybe produce some nice results!
These days I’m busy with another project, but you’re doing some very cool research!
Yeah, me too. I’m not as competent with the arduino as I’d hoped, so this is as far as I got.
Those are some cool ideas. One day I’ll bump into a local arduino expert who wants to collaborate :-)
Until then, I’m into stereo photography now. It started with a Pentax Stereo Lens Adapter, and progressed to two cameras with um… similar lenses, lol.
