No metadata on exported jpegs. Again

Hello. I’m a bit new to Darktable and so far I have found it to be very good. Big learning curve but I’m ready for it.

However. Here we go…. I have hunted the internet for a solution to this one and I have seen others talking about it but so far nothing has worked that I can find, so I’m reaching out here to see if there is a fix.

I’m using the latest version of Darktable, downloaded last week for a MAC M1.

Once I have processed a photo and export it, I find that there is no EXIF data attached which is causing a bit of a problem for my hosting software for photos.

If I process photos using using another RAW processing app there is no problem.

I’d like to use Darktable and yes this has cropped up before, I know, but if anyone can give me a quick two line fix I’d be grateful.

Many thanks

Dj

Im not on a Mac, Windows for me but my last jpg seems to have a good bit of data…

What does it say in the preference menu from the export module (accessible through the hamburger menu in the module’s title bar)?

I told you I was new to Darktable… I’m so ashamed of myself… @rvietor and @priort Thank you for pointing me in the right direction, why I didn’t look there before…

I will hang my head in shame and skulk off. I feel suitably humiliated… :rofl:

Thanks very much indeed for your help. I appreciate it

Dj

No need I am sure it will be #1 in a long list of discoveries…:slight_smile:
