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.
I managed to change the image by just shining a torch into it during the calibration and the scan. This is exciting, I might be making progress :-)
Thats really Cool! Thanks for letting me know, this might be the impetus I needed to go back to working on the 220 camera!
So, when I say "change the image", I mean the torch does affect the calibration, in the sense that I get different patterns of stripes based on the position of the torch, but it's still just outputting stripes.
Here are two scans I made by waving the torch around randomly during the calibration, then resting the torch on the glass.
For some reason each pixel is just outputing the same brightness for the whole duration of the scan, except for that black spot where the torch is, which is weird.
@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.
