Scriptable Image Processing System (Sips) ¶ In general, when converting images, the resolution of the generated JPEG files can be limited with the environment variable PHOTOPRISM_JPEG_SIZE or the CLI parameter -jpeg-size. RawTherapee cannot limit the resolution of JPEG files when converting files from other formats such as RAW, DNG, HEIC or AVIF. If it used by default if Darktable isn't installed or disabled. If installed, RawTherapee CLI can also be used for RAW image conversion. Running darktable-cli or any other binary that does the job (see above) seems to be the way to go. The idea is postponed until a clear benefit becomes visible. However this requires calling/wrapping a large number of C functions and also has other disadvantages. We had the idea to use cgo and link directly against libdarktable.so to convert RAW images to JPEG, see darktable-dev mailing list. Note that PhotoPrism will only run one instance of darktable-cli at the same time if the PHOTOPRISM_RAW_PRESETS config option is enabled, so existing Darktable presets can be applied (requires an exclusive lock). If installed, Darktable CLI can be used for RAW image conversion. Advanced edits, such as lens or color corrections, will likely not be applied. You have an open format, but you still suffer from vendor lock-in - probably not entirely unintentional on Adobe's part.įrom our experience, some basic edits done with Adobe tools - such as cropping - might be preserved when you convert the same RAW image with other software like Darktable. If you think that's confusing, well, that's because it is. In other words, just because an application generally supports XMP that doesn't mean it can use metadata created with another application or by another vendor like Adobe. However, XMP is only a "container" format, so the fields (namespaces) used there to indicate how an image should be converted (as well as other metadata) differ between Lightroom/Photoshop, Darktable, and RawTherapee. Darktable fully supports XMP sidecar files, RawTherapee might only partially.
PhotoPrism currently supports Darktable and RawTherapee as RAW image converters (as well as Sips on macOS). It can also be triggered manually in a terminal with the photoprism convert command. This is done during import or initial indexing. Since web browsers generally cannot display RAW image files directly, they must be converted. A full list of file types and extensions can be found in our Knowledge Base. Our goal is to provide top-notch support for all RAW images, regardless of camera make and model.
Newer mobile phones may also be able to capture images in RAW mode. Professional and semi-professional photographers often keep their originals in a lossless RAW format, close to how they were taken with the physical sensor, rather than in a compressed image format like JPEG, especially if they shoot with a digital SLR camera.
