@paperdigits looks like this autopost thingy loses links.

How to update Darktable? Should I uninstall and reinstall the latest version?

4

Unfortunately we don’t know what operating system you are on or where you normally install your packages from.

5

Windows 10

6

Just run the installer of the new version. It will recognize the old one and ask, if it should uninstall before continuing. Answer “Yes” and you’re fine. Your settings and edits will be preserved.

Support for Panasonic S5/S1R/S1 hi-res/pixel-shift/live composite/multi-exposure modes was added, but is missing from the release notes.

What’s the preferred way to update on Linux (Pop! OS)?

12

either ask your distro or use the matching package from the OBS. see install page on darktable.org

13

I see that the OM-1 has ‘base support’ now. Does ‘base support’ mean that something is still missing and the camera is not fully supported yet?

Jan.

OK thanks. What happens to the down rev? Do I need to remove it?

15

If you’re on Pop OS and using the flatpak, it’ll be updated shortly. Just wait.

It also has the noise profile, as mentioned in the release notes. The white balance presets are the only thing missing (but can be added easily manually without rebuilding).

17

Thank you, but I don’t understand well what you mean by ‘can easily be installed without manually rebuilding’. I am just a naive user and I cannot build DT by myself, I can only download an installer and install DT on my Windows 10 computer. If I have done that, how can I add the white balance presets? And if not possible: what are the consequences of not having these presets?

18

I did say without rebuilding.

By editing, or replacing the wb_presets.json text file.

You just won’t be able to select e.g. exact “Tungsten”, “Daylight”, or “Shade” etc. WB coefficients that match the ones you could set in the camera and OM System think are right for this camera under particular illumination. You will still be able to manually play w/ the WB coefficients/tint/temperature sliders to your heart’s content in darktable (or use the automatic “as shot” WB that the camera detected and reported), but just won’t be able to “preview” what a particular camera preset would have given you with a single click if you had hypothetically set the camera like that during the shoot.

But we digress - this topic is about dt 4.2.1, not about the OM-1.

Thank you for the share

compression mode lossless for sony ILCE-7M4 don’t work … why?

21

Welcome! The release notes clearly state that Sony lossless support is missing, i.e. it is not implemented yet.
