I stumbled onto another use for my contraption. I was invited to a life drawing class, and I’m terrible at drawing, so I replaced the scanner with just a sheet of blank paper, and I drew around the image that was formed on the paper.
The scale is limited by the lens I was using. These two are about A5, but I could have drawn them larger if I was sitting closer, or using a longer lens.
Lighting was an important aspect. The room was dark, and the model was under stage lights, and I was working under the hood.
I’ve always wanted to try a Camera Lucida, but it’s difficult to justify buying the prism. Maybe I’ll try some kind of teleprompter type setup next time.
@Leavingoldhabits Hi again, can I ask you some technical questions? I’m struggling modify my scanner. I’ve removed the clips holding the PCB, and I even made a test scan in that state, and it still worked. Then I spent hours milling out the pinhole array. But when I assembled it again, I get weird scans.
I have modified two different scanners. LiDe 110 - I get a tall narrow PNG file with some digital noise. I assumed I damaged the sensor, or a ribbon cable or something, so I shelved it, and looked for another scanner.
N650U - I took more care modifying this one. I get a full width PNG file, but it has a narrow strip of white on one side, and black everywhere else. I wonder if it is related to the initial calibration that it does before scanning.
Have you encountered anything like this? Do you have any advice?
