Thanks, that's very encouraging of you :) This was the first time I'd ever made a theme (or even used CSS) so it was quite a long process. It's really nice to hear that someone else has found value in it.

So many people seem to be piling on Gimp because of its UI (at least some of it is unwarranted and due to reputation I’m sure), I wouldn’t understimate the potential impact of a “simple” theme.

You know just this afternoon I started wondering the same thing... It kind of blew my mind to think that all the vitriol online about the UI could just be a case of theming. No one is very specific about their complaints, so it hadn't crossed my mind.

I think if I get a good response to my dark theme too I will approach the devs and offer to help implement it as a core part of GIMP. BTW if you fancy testing it out let me know - I'd appreciate it getting tested on another system before I release it.

Thanks! Yes, I thought about it, although it would need some additional work as each in-built GIMP theme is structured to draw on common files, whereas mine are standalone. Totally possible though. Maybe when I have a complete set (Grey, Dark and Light), and if they're popular, I'll post something on the Gitlab and see what they say!

Ah good old flatpak strikes again.

I'd forgotten that flatpak is a pain for this and I ended up manually working around it.

I'm thinking of adding the following to the download page:

"When installed via Flatpak, GIMP folders can be hard to find. I recommend creating your own folder for downloaded themes and adding it to GIMP: Create a new folder e.g 'my-gimp-themes' somewhere that makes sense to you and then place the unzipped PrintroomExpertSuperflat folder inside it. Then, in GIMP, go to Edit > Preferences > Folders > Themes, click the 'Add a new folder' button on the left and then the 'Open a file selector...' button on the right and select your my-gimp-themes folder. Finally, click the OK button. New themes will become avalable after restarting GIMP. All further theme downloads can be placed in the my-gimp-themes folder."

Would you mind letting me know if that makes sense and works for you? Thanks!

Cool, let me know what you think - I'm open to feedback 👍

Yeah! The workarounds I had before were complicated and didn't perform very well, so this is a major improvement.

I suspect that it will be easy for the GIMP team to make this a new layer type of its own and make it even simpler too.

I made a theme which is more professional-looking and less busy/cramped if you're interested:

I'm about to release a dark version of it too.

I don't work with HDR much, but have you tried setting it to 32bit linear floating-point?

I love how much simpler it is in this release to make independent effects/adjustment layers. You just make a group layer and set the mode to 'Pass through'. Then the adjustments/effects/filters you put on it are a) applied to all layers below it b) fully non-destructive and c) can have their own mask.

The number of adjustments you can make non-destructively - and have full control over - makes GIMP 3.2 the most powerful non-destructive editor that I know of.

There are some really nice film simulations in Rawtherapee under the Colour tab and I would try this first. I personally really like the Polaroid ones.

Another great (and very flexible) option is the G'MIC plugin in GIMP. Go to Colours > Colour Presets and try some out. You can add and configure grain under Filters in GIMP. This might be a good option if you want lots of control and are willing to learn a bit.

Feel free to send me a message - I help people get up and running with free and open source photography software.

I use Libreoffice for all of my business admin, from invoices to pricing models. It's fantastic software.

I had a similar thing. I started using Linux for privacy reasons and over the course of replacing all of the proprietary software I was using I fell in love with FOSS. Especially GIMP and other photography-related software.
