I’m a UK-based photographer specialising in photographing people and artwork. I also teach FOSS (free and open source) software relating to photography and graphic design, both in-person and online via videolink. If you need help with GIMP, RawTherapee, Geeqie or Shotwell get in touch :)

  • Just to clarify what others are saying: the ‘software store’ (Discover in your case) is just the graphical application that you use to manage the software installed on your computer. The repositories, aka ‘repos’ are the sources of that software. There are people whose job it is to vet the software in those repositories and make sure that it’s safe. Flatpak is a packaging format. The biggest repository (and what you likely have enabled) for flatpaks is Flathub. If you’re installing software from the Debian repo and Flathub you should be fine. You should be able to verify which repositories are enabled via the Discover app. You have the freedom to add other repositories too, but it will be your own responsibility to evaluate whether those sources are trustworthy if you do.

    Long story short, if you just use Debian as it is, you are fine.





  • 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.


  • I’ve asked the same question in the past, and see it keep coming up. The lack of something centralised or coordinated for donations is a massive missed opportunity for FOSS.

    This is exactly the sort of thing I think the FSF should take on. They are a nonprofit which exists to promote free software, and I think this should include the freedom to donate and receive funds. They are smart people and I’m sure they could figure out how to do it in an efficient way.


  • 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.
