opensource software for photography like Darktable then Linux mint is a great option.
There is also RawTherapee; which I currently have in my setup, but still haven't make too much use of, since I don't really shot raw that often yet.
However, if one likes rawdogging without adjustments, or would rather have adjustments done in regular editing programs like GNU GIMP, or would like to pull some shell scripting/Makefile acrobat upon one's photographs (which I do!); there is also a command-line DCraw as well.
^ Some other Free software raw editors (RawTherapee included) actually use this under the hood.
I put it on my mother-in-law's computer about 5 years ago and it's still going strong and she can use it fine (she's in her 80s and not computer literate)
Yeah, it lines up with my experience that "newbie" who use computers for just basic things: get them web browser, media player, document viewer, and in some cases, word processor; optionally with someone (often you) who they could occasionally ask questions to, and they would get it going fine.
There were some years in the past that my elderly mother (60s) would use my laptop often enough that I created a dedicated Unix user for her; and she went at it without much complaint, even that it was just a relatively-barebone Debian installation with vaguely-familiar GNOME2 desktop and unbranded Mozilla browser.
It is actually the power users like me that are more difficult to convert; because I have to get to know the new system equally as much (down to filesystem structure, boot process, tweaking, and system programming in my case) in order to feel comfortable to switch. I grew up with Windows since elementary school, and got first real experience with GNU/Linux in my high school days in 2008; but I only "slipped" into single-booting it since like... 2017, almost a decade later.
I think WIndows 11 is a really good operating system.
I see it very differently: I treat Windows version 10 and later as "
spyware disguised as an OS", not a real OS that user controls.
When Windows 8 made debut with all the UEFI "Secure Boot" (read: shackled boot) and Windows RT lockdown controversy, I already saw it as a writing on the wall that Microsoft-powered system is going down a route of "technology as a digital concentration camp". While I was using Windows as the main OS just like most people back in the days; as a Free software guy who refuse to bow down to such thing, I know that my days on Windows was now numbered.
When a chance came, I started preparing my "escape route" by buying my first laptop in my price range with best GNU/Linux compatibility-- scouring several local tech malls and expo to do so; flicked on the Freedom Boot mode, then installed my favorite distribution,
single-boot it, and live with that. (With my still-dualbooting desktop computer as a fallback if I really needed Windows for something)
^ Spoiler: that very laptop (Samsung NP370) is the laptop I'm typing this on right now.
It was definitely not a bed of roses, but I make do
(0); and customized my setup along the way for years, eventually to the point that I could live with it like second home; and I went back to Windows on desktop less and less. When Microsoft pulled the support plug on Windows 7 (the last Windows I could tolerate) in like... 2020, Windows was basically a past for me at that point.
That was how I made the switch. And yeah, like you said, the fact that I don't game much does help.
But in any case, I don't believe that going cold turkey on switching was going to do much good for serious computer users; but at least they got to dual-boot or USB-boot GNU/Linux, and find their way around to access their on-disk files (
beware of the BitLocker! (1)), and casually try out remaking their workflow there at their own pace.
With Windows 10 and 11 being tethered to the universal backdoor called Windows Update, it means Microsoft can push any malicious antifeatures
(2) upon users anytime it wants: what is "good" today might not remain good tomorrow. So,
when Microsoft pulled something nasty again (like that Recall bullcrap); people who have prepared would have an escape hatch ready for them to go their own way, instead of being effectively forced to stay under Windows like a prisoner in their own machine.
(0) I should mention here that I was a Photoshop junkie (thanks to my high school); so it goes without saying about me tearing my hairs out in the first few years of using GNU GIMP.
(1) I see the automatically-enabled BitLocker disk encryption in new Windows 11 installs (since 24H2, circa 2024) as a sinister ploy to make offline data migration as well as data access from dual-booting GNU/Linux a pain in the neck, or outright impossible if the user didn't think to manually export the key beforehand.
(2) Feature, but anti-user.
