I am looking at the images scaled on a 24" monitor and I dont have any idea of the color gamut of the monitor. It will certainly become apparent if you raise the shadows, do a bit of tonal adjustment, and then look at them at 100% particularly in areas of fine detail or areas of smooth colour gradients. The difference will probably become apparent if you look at them more closely.
An HD screen is around 2.1MP so you'd have to discard a lot of information before that loss would become apparent. If you're looking at images from a recent camera scaled to fit an HD screen, I would be surprised if you could tell the difference at normal viewing distances. Personally I find some things easier to do in GIMP than in Darktable.Īre you looking at them at 100%, or just scaled to fit your screen? If you want highest possible quality for later editing, save as TIFF or lossless WebP. Bayer pattern cameras don't have any more color information than 2x1 anyway. My Darktable is set to 92, where the transition occurs between 1x1 (4:4:4) and 2x1 (4:2:2) chroma subsampling. It is very large, and when edited it, artifacts become visible anyway. I believe that JPEG quality 100 is inadvisable. I suppose this could be a fault of the monitors or maybe my eyes but what is the 10x (roughly) difference in file size accomplishing? Where would this make a difference-in printing or on a really large 60" OLED monitor or? Comparing the 1.4 MB and the 14 MB images side by side I can not see any discernible difference between the two. I process my photos on a dual monitor desktop - the monitors are 24" BenQ's from several years ago. Increasing the slider to 100 results in a 14 MB jpg image exported. The slider defaults to 90% and yields most times a 1.4 MB jpg image. In the export settings for Darktable is a slider when 8 bit jpg is selected, to adjust the image quality and the resultant file size in the exported jpg image. I do not do any jpg post processing-if there is something I dont like in a jpg image I go back and fish the RAW image out of archives, change it and re export it in jpg.
2012 Olympus OMD EM5 and the kit lens, a 12-50 3.5-6.3 Oly lens that came with the camera. I use Darktable for all my post processing work.
