Hi amazing darktable devs. Quite the nice program you have here. I've been diving in deep over the last couple weeks, trying to optimize imagery outputs for a fast-response workflow processing tens-to-hundreds of thousands of images for 3D mapping. We have been processing DNGs but are trying to move to JPGs because working in 48 bits is hard on computing, transfer, and storage. I just posted over in darktable-users, but it seems I need to talk to the big guns.
TLDR; If darktable supported per-image auto-adjust using darktable-cli + xmp or style (or darktable configuration values) for levels/rgb levels/filmic and other modules that have auto-adjust capabilities, then I could get really good output without resorting to Capture One. JPGs processed with Capture One (auto-levels only, no base curve) give us better matching (more tie points, identical or better precision/accuracy) than DNGs in my tests, but JPGs with anything else do slightly worse. OpenImageIO and darktable are the closest I can get to Capture One, and darktable is the fastest of anything I've tried, although it would be faster if it supported parallelized export in darktable-cli. I can get good results with Darktable (comparable to Capture One) if I manually adjust images using minimal settings (no base curve, automatic levels or automatic RGB levels (with preserve colors), and/or filmic module (with preserve chromaticity). But I can't get those per-image automatic adjustments without going to each image and clicking on it and making a xmp. I've tried using darktable-cli to batch apply settings but I can only do that with settings that have the same parameters for every image. I really like being able to apply one .xmp file or one style to all images, but I would LOVE it if I could use the modules that have an auto-apply option and programmatically have the auto-apply be applied per-image. Thanks for making darktable! It's fantastic! /Andy ==================================== Andy Ritchie U.S. Geological Survey Pacific Coastal and Marine Science Center 2885 Mission St. Santa Cruz, CA 95060 Office (831) 460-7454 Cell (360) 460-9453 aritc...@usgs.gov<mailto:aritc...@usgs.gov> --------------------------------------------------------------- ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
