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.
Wow, that is all very valuable information, thank you. I feel a lot more confident attempting the surgery on the electronics now.
I had a thought about going from bw to colour. If should be possible to capture the same scene 3 times, each time with a different colour filter in front of the lens. Then merge the 3 images together as colour channels in Photoshop or similar. The filters will reduce the amount of light picked up by the sensor, which will help a bit on bright sunny days, but will require more light in a studio. Also, in a low light situation, it could be possible to capture a fourth scan with no filter, and use it for brightness information. I’m not exactly sure how to do that, but I know some cellphones use that trick.
Edit: But I also like your idea of tapping the signal to trigger external lighting.
Cathode ray dude on YouTube just dropped a feature length video on scanners, you might find it interesting!
That was worth watching, thank you.
