Thank you for the reminder! Fixed
I had high hopes that I could make them work that way, but no luck :\
Upscayl isn't much use to me, because I don't need upscaling, only noise reduction.
Aydin appears to only work on PNG files, not my RAW files
Not quite. I'm talking about high ISO images. Most of my photos are not high ISO, so most of my photos don't need this.
For a professional, they generally don't shoot in high ISO, because it degrades the image quality. They use external lighting, flashes, reflectors, fast lenses etc, anything and everything they can, to avoid shooting high ISO. So a pro, on a pro shoot, won't need dedicated noise reduction software, and can use the profiles built in to apps like darktable
I take pride in capturing the image, not relying on software to recreate it the way I wish it had been shot
Unless you're shooting flat JPGs with no photo modes enabled, and not doing any post processing, then you're not getting that result. And even if you do that, two cameras shooting the same scene will produce different images, because the process of converting RAW sensor data to the reduced colour palette and bit depth of a JPG image, involves an algorithm deciding how best to recreate (not capture) what you saw with your eye, and no two cameras do it the same way, and neither produce a "true" capture of what you saw.
Ultimately, it's a meaningless distinction. My camera does in body image compositing, allowing long exposures that updates the original frame, but only with light sources that have changed since it was taken, meaning in body software stacking that ensures point sources don't blow out on long exposures, but moving sources get tracked. It uses AI subject recognition to drive its auto focus. It has a 120frame buffer than records records directly to the buffer whilst holding the shutter button half down, and then writes them all to the card when you press, effectively letting you capture moments that you would normally have missed, because human reflexes are imperfect. And the RAW software that comes with the camera literally uses AI noise reduction.
So for me to draw the line and say that AI driven noise reduction (non generative AI at that) is a problem would be a bit hypocritical of me.
As it is, the camera hardware itself does solid noise reduction on the JPGs it produces (using algorithms built in to the firmware) giving really nice results even at high ISOs. But the only way to replicate that with a RAW file, is using the camera supplied RAW software (which doesn't work on linux), or by using a 3rd partyAI noise reduction app (which don't work on linux). If I don't use them, then I'm in the strange situation where my high ISO JPG preview photos look better than an end to end post processed RAW file.
If I was "embracing the flaws that my camera creates" I would be shooting in JPEG mode, using images mostly straight out of the camera, and they would be less noisy than what I can achieve with current linux tools.
I've been doing this for 20 years, and using m43 (or four thirds before it) for most of that time. I know what I want from my photography, and I know the tools that give it to me. What I want is for the image to look like the scene that I saw. I don't care if it's a pixel perfect match for it. I don't care about embracing the flaws that a camera introduces, flaws that don't exist when viewed through the human eye (reduced dynamic range, sensor noise etc), out of some sense of "purity". Purity that was lost the moment I pressed the shutter on a digital camera that has to encode the image in software to make it visible.
Dedicated noise reduction software like Topaz and DxO rely on the GPU. And because of that, they don't work on Wine or VMs (unless you have a dedicated GPU and can get GPU passthrough functioning).
I use darktable and digikam for every other step of my workflow, but that one step, I just can't do with Linux
Unless you have very peculiar hobbies.
Or you take your photography a bit too seriously! Good noise reduction software is next to impossible to do on Linux. It's the only reason I have a windows box in my house
If it's too resource intensive, we have a few other UI alternatives ready to go as well!
Blahaj.zone has disabled downvotes, so at least that part can't be weaponised against folk on our instance.
As for the rest of it, yeah, lemmy is better than reddit, but it did get a lot of users from reddit, so its still closer to reddit culture than I'd like. But, it's also got a lot of better aspects than reddit ever did, and hopefully that trend will continue
The way federation works is that content from remote communities doesn't federate here until one of our users subscribes to it. You made your post about a week ago, but you made it in reply to a 2 year old post on a remote community, and that community has not had any activity at all, here or on its home instance, in over 3 months.
If you are subscribed to that community now though, any future posts that get made to it will federate to us and you'll be able to interact with it. On the lemmy.pt instance, even their most active and subscribed community hasn't had any posts made to it for over 2 weeks, so if you subscribed to it after that, none of their content will have federated to us yet.
But, if you make a brand new post in one of their communities, everyone else on lemmy that is subscribe to that community will be able to see it and reply to it.
tl;dr - Federation means that existing content in old, low volume communities don't federate very well if you're the first subscriber on our instance. But once subscribed, it will work fine for future content.
Edit - Also, as others have said, check your language settings. You want to make sure that in your settings you have English, "Undetermined" and Portuguese selected (as well as any other languages you speak). If you don't select the language in your settings, lemmy hides all content tagged with that language from you. And if you don't select undetermined, lemmy hides all of the content that people haven't set a language tag for at all (which is most lemmy content)
Exactly why my instance has downvotes disabled
One of my workmates moved to Australia from Uruguay when he was 14. He only spoke Spanish at the time, which isn't very common in Australia. He's talked a few times about the different experience he had vs his sister who is a few years younger than him. He still has a noticable rioplatense accent to his english, but his sister does not. He also had to go to a special immersion class/school to get his english to the point where he could do manage in regular english language schooling, but his sister did not, and managed just fine being moved straight in to english speaking schools.
Ultimately, he said that he got there pretty quickly, because he was still a kid, but he spent the best part of a year feeling isolated from his peers, except when he was in the immersion class.
