写真が大好きです。レンズを通じて画像を見ること、それを整理して物語を構成すること、そして結果の写真を扱うことに特別な感覚があります。Canon AE-1P、 analog SLR that my dad traveled with around the world before settling down in the States. フィルム写真は単純だが、 particular: you expose reflected light against a strip of plastic and burn-in a chemical image. For years my process looked like this: load film and take photos, send the film to a lab and wait for development, pick up said film, cut the negatives into strips, load them into a holder, capture the negative of each frame in with a specialized scanner, open every file in darktable, invert it by hand, make topical edits, then decide where to store and/or share the exported image. At first this was an exciting process for me.

Then as the number of rolls increased, so did my effort to do this for 36 frames per roll. On average it would take me about 4 hours to fully scan in a roll of 36 photos and complete edits. It requires delicacy in handling film especially to avoid dust or scratches on the final image.

Safe to say, the process grew weary on me quite fast. I was spending more time processing my images than actually taking them. So I began looking for ways I could cut some time, or as the CEOs like to say, streamline operations across my personal digital lab.

Giving Claude destructive hardware capabilities My first hypothesis was if I could take myself out of the loop entirely. I'd have Claude drive the scanner over SANE and handle scanning, colour conversion and edits end to end. On the first scan, Claude used SANE with inversed X/Y scanbed directions and nearly broke the gear mechanism inside the scanner.

So I unfortunately killed time by needing to perform an emergency surgical operation on the scanner to save $200 from being spent on a new one. Chat: Blank white scans Sep 20, 2026 Shan 4:54 pm there is definitely film in there, maybe its the scanning settings you opted for Claude 4:56 pm I've been tracing why the scans come out white, and your guess about settings can be ruled out. Instead, every one of the 856 rows is identical: smooth vertical bands from the lamp's uneven illumination, with zero variation from top to bottom and no image detail.

So the sensor saw the same unobstructed line of light for the whole scan. Shan 5:01 pm i tried with vuescan, but the sensor or the carriage is not moving, you must have done something wrong Shan 5:04 pm its definitely in a bad state. can you check on the scanner, until i let you know its moving. i did hear some clicking earlier, so it might have been going an opposite direction Claude 5:05 pm I found what the clicking was, and it came from my scans. At the end of every scan, the genesys backend sends the carriage back with a blind reverse move: 7010 steps at 900 dpi, and more at 3600.

It assumes the carriage travelled forward during the scan. So each scan ended with the motor driving a carriage that was already parked backwards into its end stop. That is the clicking you heard, and your read on the direction was right.

I ran seven scans, so it happened seven times. Surgery. Pushing a rod and gear that did not want to be pushed back into place.

I ended up working with what was already working well. Vue Scan was the software I'd licensed way back when - given that it had the best compatibility with my scanner, and.
