It doesn't affect me, but just out of interest, is it a case of NO .dng files are supported, or just .dng files created from that particular camera type?

These DNGs are not officially supported. >From a recent discussion: Tobias Ellinghaus schrieb am 04.04.2018 um 13:36: Am Mittwoch, 4. April 2018, 13:15:39 CEST schrieb Timur Irikovich Davletshin: Hello everybody! Just decided to play with DNG converter and discovered problem related to lens data interpretation by DT (2.4.2). 1. NEF file loaded by DT applies correct lens parameters. Lens info shown by DT: Nikon AF-S DX Nikkor 18-55mm f/3.5-5.6G VR II 2. DNG file cannot apply it because wrong EXIF information is used (short lens name vs. full). Lens info shown by DT: 18.0-55.0 mm f/3.5-5.6 3. Focus information also is lost in DNG. That's why we tell everyone to never convert to DNG. Tobias [...] That's the short answer. The long answer could look like this: - DNG is a RAW file format like NEF or CR2 or ORF or ... - this is true only if the file comes out-of-camera this way. The devs try to support as many RAW formats as they can - if user-provided samples are available. Many of the proprietary RAW-Formats come with different flavours based on Camera Model, Camera Settings etc. So testing this is a tremendous effort which has to be done on every (minor) release of darktable. Adding a simple RAW=>DNG converter would double this effort. But: adding more RAW=>DNG converters would multiply this effort since every proprietary flavour of any proprietary format would have to be tested against every (proprietary or not) RAW=>DNG Converter. So I totally understand the devs to care about original RAWs and not on any variant of those. [Perhaps a prominent message about this would be a good thing in the manual/list of supported cameras?] Please use the original RAW files of your camera. Looking at this table https://www.darktable.org/resources/camera-support/ it seems your camera isn't supported at all. You could upload samples to https://raw.pixls.us/ to help support this camera in future. -- regards Bernhard https://www.bilddateien.de Bruce Williams schrieb am 14.11.18 um 21:02: Gah! My bad!

Except this, when in darkroom, the small preview at the bottom of the screen of the pic I currently develop, it seems to be OK, in most of the cases, but not always. Thans, Fotis Zagoras.

Did the image display correctly? Cheers, Bruce Williams. On Thu., 15 Nov. 2018, 05:55 Φώτης Ζάγορας <[email protected] wrote: > Hi!
