Hi Greig, You basically want to replace some EXIF information present in the raw file. A number of people (including me) would strongly avoid ever modifying a raw file. These are full of dragons. First I would make a backup of the raw files for fear or any change triggering some wrong

[darktable-user] Presettings

2020-11-15 Thread Peter Schlaufer
Hello to all I need some help: A few months ago, I imported some 25'000 pictures in dt 3.2 with the setting "display referred" meaning that the basecurve is autoapplied. I found out now that most of these pictures have far to dark dark shadows, sometimes to an extreme extent. Some of them I

[darktable-user] Lens correction not working

2020-11-15 Thread t_drei
Hi, Lens correction doesn't work anymore for my Sony RX10M4. In earlier versions of darktable, the camera was recognized and lens correction (geometry) worked just fine. Now, there's no recognition of the camera, and I cannot choose it from the list (my other two cameras are still there, e.g.

Hi Peter, Jan's solution of creating a style would work. Another solution would be to set the preferences for "Scene referred" processing and in the duplicate manager of lighttable create a 'virgin copy'. You can then delete the base curve version if it is no longer needed. Keep in mind

I am slowly picking mmy way through many of my images and reprocessing based on the-filmic-way . my finding was that there was often more elements than the basecurve that needed to be changed so I now simply make a duplicate and start-over with a number of presets. The big advantage of

thanks, Šarūnas, I have two Darktable systems, based on Lenovo TS140, one with AMD, the other with Nvidia Quadro 400. Neither of the two manage OpenCL.. 0.039390 [opencl_init] found opencl runtime library 'libOpenCL' 0.039412 [opencl_init] opencl library 'libOpenCL' found on your system and

It would be more simple do to create a style that disable the basecurve and enable filmic: 1. Open one of the pictures in the darkroom 2. disable basecurve 3. enable filmic 4. go back to lighttable 5. save style with (only) basecurve and filmic checked Now you can apply the saved style to every

[darktable-user] IPTC Metadata Export

2020-11-15 Thread Ralf Kerkhoff
Hi, just wondering how to manage this: I would like to export the Image creation time within the IPTC section of the Metadata. Darktable provides the "Tag": Iptc.Application2.TimeCreated in the Export Metadata section. But what would be the correct formula for this? Any hints are welcome Ralf

Re: [darktable-user] Scanning and EXIF information

2020-11-15 Thread William Ferguson
Another way to handle the scans is import them into darktable, then update the EXIF data in the database. There is a lua script to adjust or set time for an image or set of images called, appropriately enough, adjust_time. It's located at https://github.com/wpferguson/extra-dt-lua-scripts. On

Thanks Stephane, I have taken your warning on messing with RAW files on board. I can produce a text file with my information and store it with the RAW files. Is it possible to change the data exported to a jpg or png to reflect the settings for the images? And leave the RAW files untouched?
