    Loving your channel Andy. I’m rediscovering Raw Therapee with your help.

    As usual Andy, great job. RT just blows me away how deep it is, and I think the learning curve would be just too steep without the guidance your tutorials give. I just wish I had more spare time to play with it. All the best to you and your family.👌👍

      Thanks Mark, very kind of you! To be honest it still blows me away at times so there's lots more to come for sure. Thought about you when I heard about Covid spike your way - stay safe and well matey

    Thanks for your tutorial. The introduction into wavelet denoising was very helpful!

    Thanks Andy for continuing on the wavelets. Looking forward to next episodes covering it. Great job. Have a nice weekend.

    "PLEASE NOTE: This is A Rough, Simple Example that WORKS - but only scratches the surface of what's possible! " Jeez Andy... if this is just "scratching the surface" how more bloody marvellous can an image be made 👀 Fantastic work - and was I really watching for 3/4 hour for those "rough, simple example steps? You well deserve to be given a Professorship matey 👌🍾✔ And not to forget the "hero of the hour" giving you the evil eye 👌👍💕 😉

      @@AndyAstbury Can't wait 👍 It's great watching you go deeper and deeper in to this program Andy. I don't spend a lot of time when in LR, just a few basics to get where I think (?) a photo needs to be and, basically, job done. However you definitely know your way around and how to get 'acceptable' (to some?) images far, far more so. A Master of your Art matey - no p take... you know what your're on about 👌😉

    Thanks Andy. Your tutorials are brilliant. Totally changed the way I look at and edit pictures. I have managed to sharpen pictures that i thought were a lost cause. Not always images to print but just to enjoy.

    Thanks again Andy, I had no idea how that part of RT works. Impressive outcome given the starting ISO.
    Lovely image too.

      @AndyAstbury  4 роки тому +1

      Cheers Peter 🍻🍻 That was just the bare bones - it's even better in the new development build with the new tools for both denoise and edge. As for the image, thanks - he's a handsome fella!

    Having viewed 4 or 5 of your tutorials (and following along with my images), I can honestly say this content is GOLD! Have you considered offering a course on Raw Therapee in Udemy? (Not that I want to lose "free" access to your UA-cam content....but....what I have already learned here is worth the cost of a paid course in Udemy 10x over.)

    Great video Andy. This level of control is phenomenal compared to things like Topaz Denoise or DxO Define, where the specifics of what happens "under the hood" are completely hidden.

    I am using the latest dev version.
    Looks like i have to bring up the denoise levels much more to see any effect.

  • @janvangastel6763
    @janvangastel6763 3 роки тому

    Thank you for making this video. If I saw it right, there's a kind of balance we need to accomplish in removing noise were we want it and keeping or adding sharpness/contrast were we want it. Would it not be much easier and less time consuming if RT had some kind of selection tool? We then could select (parts of) the background and reduce the noise or select (parts of) the subject - i.c. the bird - and ad sharpness and/or contast right were we want it.

    • @AndyAstbury

      In a way, yes it would, but a freehand selection tool is difficult to engineer - so difficult Adobe ain't managed it in Lightroom yet!

    Could you make a wavelet guide on version 5.9 aswell as there are additional controls?

    • @AndyAstbury
      @AndyAstbury  4 роки тому

      Yes I will do that once the 5.9 public release is available.

    As always, most enlightening Andy and plenty to ponder. There's no doubt this is an immensely powerful tool. I wonder if you've had chance to have a gander at Topaz Denoise AI? I've recently acquired this software and have been hugely impressed. I realise there is nothing like the control you'd get using RawTherapee but none the less the results are very good indeed. Just wondered what you thought of it? 😊

    • @AndyAstbury
      @AndyAstbury  4 роки тому

      $80 for a plugin that denoises pixel-based images, vs denoising raw data - I'll take denoising raw data all day long. I stopped using denoising plugins a long time ago, with the slight exception of Nik Define for astro shots, but I stopped using that once Ralph Hill brought out SLS and I began shooting black frames for astro noise reduction - which is FAR better, but a bit more work with the camera.
      Nope, spending $80 on noise reduction defies logic to me, and noise reduction done at the raw level will always make for superior performance - utter madness.

    • @dunnymonster
      @dunnymonster 4 роки тому

      @@AndyAstbury Indeed, as far as I am aware Topaz AI cannot work directly on the RAW file itself. I use it as a plugin via photoshop as a smart object so at best it's going to be working on a converted TIFF. That said whatever its doing under the hood is perhaps the best noise reduction software I've used to date. As I alluded to, I've no doubt using your technique through Rawtherape would yield vastly superior results however. 🙂

    • @AndyAstbury
      @AndyAstbury  4 роки тому

      Ha, now I take back some of what I said! Just been and tried the latest version - you can drop a raw file into it and spit it out again as a DNG! Just tried it on a 10,000ISO .CR2 file - if I turn the noise reduction down to 1 (lowest setting that does anything) it makes the shadows go nearly like plastic. There's some horrible sharpening on there, but you can turn all that off as long as you are in DenoiseAI and NOT AIClear (which looks really bad to me).
      Overall though, the DNG looks okay - certainly better than the preview which has some strange crisscross pattern on it.
