    What's your biggest challenge when working with pictures?

      Maybe how to automate basic settings which are always the same, like for the noise adjustment?

      Great idea, ytutorial learning ! This is possible using Processing Profiles in the upper right corner, but has a few caveats. I'll add this to my video schedule. Thanks!

      Just to share, I posted a new video just now on how to create reusable adjustment templates (processing profiles) for #RawTherapee - Hope it helps! ruclips.net/video/FRXivckMz_w/видео.html

    Great video. I'd love if you made it with no music in the background. I can always play music in the background if I wanted to. Thanks!

      Hi Imaginative Design! Thank you so much for watching! Yes, using music has always been something that went back and forth with. It feels like it's missing if there's nothing in the background so I've been experimenting with trying to find the sweet spot of just audible but not overpowering. My latest videos seem to have balanced this much better, but the older ones still show my learning experiences along the way. I very much appreciate you checking out this video!

    Hi,
    The high and low frequencies are not colours ! high frequencies are the small details in the picture.
    Its difficult to explain.

    Hi Nate! Sorry fot not responding to your videos but now when you're back to rawtherapee I'm in. I'm familiar with most of the tools in the noise reduction section on rawtherapee. However I had an issue i couldn't solve. I expanded my camera, canon 6D mk2, to 100,000 and shot outside my home. I tried everything in my power and knowledge to get rid of the noise combining rawtherapee and gimp layer work but in vein. I can't express my frustrations. I'm on Linux and I hardly ever use windows. I considered buying topaz AI but then I've found a way to it more or less. There's a new AI upscaling software for Linux. It's called upscayl. I downscaled the photo's size to about 1500X1000 and upscaled it with this software. The noise is gone. I'll try other sizes in the future. Upscayl is only beginning its development. I believe that future versions will bring AI noise reduction and other tool.

      Hi Arnon! Great to hear from you! Thank you for sharing - definitely going to take a look at Upscayl - Been wrestling with noise for a while now and I see that Upscayl has a batch tool included, which could be a HUGE help! Working on high ISO for night shots always seems to give me trouble, even with prolonged exposure. I'll test this out and share any new findings - Thank you, Arnon!

      Interesting idea. There are ai models that do noise/compression artifact reduction instead of actual upscaling. I would use Chainner with upscaling node and download model with 1 to 1 scaling. This way reducing image size is not required. It also works well for video but you need small model to finish processing in less than 1 day :)

      @@krzysiek2768 The secret is to upscale the photo back to its original size in digital art mode. Then place both photos on top of each other gimp and reduce opacity. I usually do it twice. First round ca down to 75% create new from visible and respect the process with the new layer. The result is nearly identical to the results from Lightroom or topaz.

    Nice video man, very useful. I have a Fuji XT4 and the raw files are often quite noisy. This with GIMP and GMIC has produced high quality noise free images.

      Hi Odaly'sPOV! The noise control works more on a "micro" level with RawTherepee (zooming in quite a bit shows the change). For more holistic noise control, I've found that the wavelet tool works better and made a video about here - ruclips.net/video/7InQ6_pcqts/видео.html - Hope that helps!

    HI, can you explain to me one thing?
    When I zoom out after adjusting it comes back to the original state and nothing changes, but when I zoom in again it's changed. What have I did wrong?

    • @Photolearningism
      @Photolearningism  Год назад +1

      Hi Bartosz! I've noticed this too - to my knowledge, noise filtering works on a very fine level that won't necessarily clean up larger scale noise. What does help on that level is using wavelets - I made an updated video exploring it here - hope it helps! ruclips.net/video/7InQ6_pcqts/видео.html

    450 ISO ... that's a free one. Try with heavy noise and maybe show how to use the wavelet noise reduction tool. I have not succeeded in removing noise above 4000 ISO in RT, yet - but I am motivated for learning it. I like many of the features in RT, but noise reduction is not one of the strongest, imho.

    • @Photolearningism
      @Photolearningism  2 года назад +1

      Thanks! I'll look into the wavelet noise control and add it to the list!

      Hi Eigil! Circling back, I just posted a brand video on blending out noise using wavelets (RawTherapee and DarkTable), demonstrating on a picture taking during sunrise, ISO 8000 - ruclips.net/video/7InQ6_pcqts/видео.html - Hope it helps!

    There's something wrong, this video pops up when i search for "defringe in raw therapee".

    • @Photolearningism

      Hi Daniel! This is interesting - I reviewed the video description and tags just in case something was misapplied. Presently, the term "defringe" doesn't appear in the details, so I think RUclips is making a data relationship between "defringe" and "denoise", as they are somewhat related in principle, but stem from different issues. Just in case it helps, here is the #RawTherapee user guide for the defringe feature - hope it helps some! rawpedia.rawtherapee.com/Defringe
