Re: [darktable-user] Darktable 3.2, a short review
Hi Terry, thanks for this view on DT and LR. I agree on everything I think, although I'm a Linux user who had to buy a Windows pc to use LR for the first time. Since you use both extensively, what is your opininion on highlight and shadow recovery in DT versus LR? My experience is that LR gives better and more natural results so far. I used masks a lot in DT, but at a certain point highlight recovery just makes the area look more grey, not a recovery at all. Op 26-08-2020 om 01:52 schreef Terry Pinfold: Hi Marc, one of my jobs is teaching photography and imaging classes for Adult Education classes. I have done this since 2002. Because of this I need to have Photoshop and LR loaded on my computers for teaching. I also have creative cloud access to every Adobe program because of my daytime job at a University. Well over ten years years ago I stopped using Photoshop for anything but teaching purposes. I exclusively use and recommend GIMP in preference to Photoshop. I have a perpetual licence of Adobe CS6 Master suite which includes Photoshop and all the programs needed by a graphic artist. If I was a graphic artist or web designer I might use Photoshop as part of the suite of programs to do my job. Photoshop after all is a graphic artist's tool that photographers just happen to have a use for. Since I am a photographer I find GIMP is suitable to my needs as a photographer and I don't need a suite of programs. I love the ease that I can open images as layers, the way I can create my own keyboard shortcuts to speed up my workflow with GIMP. I also love that there is no economic barrier to my students when I recommend GIMP over Photoshop. I feel there is some snob appeal in people picking PS over GIMP. I have often heard the comment "you get what you pay for". GIMP was used to make films like Harry Potter and Stewart Little so I don't see them using a B-grade program. As for LR, I tried version 1, 2, 3, 4, and 5 as trial versions when they were released. Just didn't like them. Then LR6 was released and I am not sure if I changed or LR changed, but I fell in love with LR. I am never going to knock LR. Adobe have built PS for Graphic artists but with LR they designed a program for photographers and did a great job. I would never try and talk anyone out of using LR. It is well designed, relatively simple to use and gives good results fast. However, I came across some very challenging images that LR was incapable of processing to the required standard so the prints could be exhibited and sold through an art gallery. I invested a lot of time on these images for the person because I love challenges. During this process I ended up exploring both RawTherapee and Darktable. RawTherapee is a great program at tackling noise issues. This starts with selecting specific demosaic algorithms and ends with removing salt and pepper noise and hot pixels. However, Rawtherapee is limited to global adjustments for the whole image. On the other hand, Darktable has masking options to localise adjustments. It is these masking options that new users of DT should focus on first. When you get used to working with various drawn and parametric masks you will fall in love with DT and see its real potential. Coming from LR I first reached for the brush to draw the mask. It is not as user friendly as LR's brush and will leave you disappointed. I suspect many people give up on DT because of this. But, then I stumbled on the drawn mask using the path option. This allowed me to draw along the skyline of mountain ranges, or the bright side or shadow side of a person's face, or select a region in a streetscape and then I could apply an exposure correct. The result initially can look terrible but then I can reshape and feather the path until I get a smooth and invisible transition. The results left for dead what I could do with LR's adjustment brush. I just needed to learn to use this one new tool and then I became a DT devotee. My advice to new users is learn to use the drawn mask with the path tool (read the manual) and use this tool to do simple exposure corrections on your images. That is the first lesson to learn in DT. Later worry about batch processing, styles, Filmic and all the other modules. As for the question of speed. LR works quicker on images because it is only working on a preview of the image. DT is slower because it does more intensive processing of the images. But I believe this is being addressed to some degree in the newer versions. Maybe one of the developers could comment on this. I have a windows computer and I read that it works fastest on Linux computers. BTW, if a person has a perpetual licence for Photoshop or LR such as your LR5 and they have a Windows computer all is fine. But if they are a Mac user and they upgrade to Catalina OS the perpetual LR and PS will no longer be compatible. They will be forced into a subscription for the
RE: [darktable-user] Darktable 3.2, a short review
Terry, Jack, Thank you for your feedback. Terry, I was really waiting your reply since I suspected you had good experience with LR and dt. This confirms also that dt can use a powerful computer if one doesn’t want to feel refrained in his creativity. I am indeed experimenting masks, including a parametric mask inside a drawn mask. And that often gives remarkable results. I most often use it with the basic adjustments module. Jack, I feel also that shadow recovery in LR is easier. But have you tried dt’s tone equaliser with its included mask tuning (there is a good video by Bruce Williams) ? On a few of my landscape pictures it gave me great results. However I found it not always useable and then I use masks.

Re: [darktable-user] Darktable 3.2, a short review
Hi Marc, You know, I don't mind fiddling around with many modules to get the best possible image , if I have the time and it is only one or two images. But when I went to for instance horse jumping competition, a city trip or whatever, with lots of different lighting conditions, and I have 100 or 200 images to process for a client, I want to do it easy and fast and good. With DT many times I have the feeling I have to start all over with every image, even when I have several presets saved. That's the reason I mainly use LR at this moment, while learning to work faster with DT. Until now I have been able to use LR for almost every image, although sometimes I open an image in DT because local contrast is nicer.

[darktable-user] Infrared with darktable 3.2.1 and Filmic RGB v4
Hi All, After having studied Aurélien Pierre's videos and some informative texts about the new approach with Exposure + Filmic RGB v4, I'd like to add my experiences with processing infrared shots to all the other positive feedbacks... It took me some time to understand the filmic module and the theory behind it. But in the end I am able to process my infrared shots with lesser development steps and better results than before. It's a pleasure for me now to work more efficient with darktable 3.2.1 Thanks to all the developers involved!!

When I crop a photo in darkroom and return to lighttable the cropping is lost. If I do Ctl-e in darkroom, the exported image is the full photo without cropping. This seems to have occurred after the upgrade to 3.2.1 but I am not sure. I have tried to re-install, checked file permissions, deleted settings and database.

[darktable-user] Change aspect ratio? (non uniform scale)
Sometimes, if no scanner is around, I take photos of documents or postcards. These can be corrected fairly quickly using keystone and crop in the “crop and rotate” module, plus some color correction. After correction, however, the aspect ratio will never be perfect. An A4 page, for example, will be slightly off the √2 aspect ratio. Is there a way to correct aspect ratio from within Darktable? Gimp could do it, but then I don’t want to use another tool, especially since everything else is so nice and quick with Darktable. The only thing that would be even better is to fix the aspect ratio when converting the exported images to PDF using some PDF command. The nice tool [img2pdf][1] unfortunately can’t do it.
