Hello, I’m using a digital camera to scan film negatives, and I’ve created a custom PCB with to light the negatives with red, green, and blue light of specific wavelengths. To control the LED board, issue commands over serial to turn the LEDs on/off, change their intensity, etc. I have a program on my computer that scripts these operations, so I can tell the board “turn on the red channel, wait 1 second, then blue, wait 1 second” etc.
It would be ideal if I could control my tethered camera at the same time through darktable. Darktable’s tethering mode is great, but I’m not aware of any method to trigger a capture externally. Ideally I would have a process running on my computer that issues commands to the LED board, and communicates with darktable using some kind of IPC to trigger a capture at the right time. This way I could synchronize the LED board with the camera and automate part of the capture process. Is there a built in way to do this in darktable? Thanks.____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
