![]() ![]() If you don't have original images in 16bit, first step after opening it in photoshop is, to increase the colordepth from 8 to 16. Only work in 16 bit depth mode! Everytime!! (No, - no exceptions!)Īt the last step, procede reduce the color depth from 16 bit to 8 bit, but only for variations that you want to share / upload, etc! KEEP your 16 bit ORIGINAL locally! I suggest to read your first link to brasseur, but in regard of Photoshop and how it should be used. there are also only 8bit engines!)Īnd set back the colordepth to 8 or lower, if the original has lower depth:īut it looks like your local workflow isn't correct. Go into 16bit mode (if available in this imagick engine. If there isn't one available, assume default value: Look for a gamma setting shiped with the image: Hey already follow the rules you linked too, with a bit more individuality: I am out of my league with this, technical knowledge wise but I'll try to keep up Would be nice to get a discussion going here. One of the above plus these rather involved technical reccomendations (tldr: convert to linear RGB, resize, convert back) Colorspace handling changes between imagick versions The way the Imagick module detects/ignores profiles ![]() The way the srgb profile is embedded in the jpg Need to find time to do more structured testing though. I tried multiple variations, with embedded and excluded srgb profile, "convert to srgb" on and off, but the result appears to be the same darker, muted image. Images with an embedded (srgb) profile that were exported via Photoshop's "save for web" function with "convert to srgb" and "embed profile" ON, somehow result in muted colors and a darker image, (actually it looks very much like when you would assign an srgb profile to an image that was already converted to srgb before, not dramatic, but quite noticeable with e.g. I noticed that In some cases Image Magic resized jpgs appear darker than the original, and after some digging it appears to involve various factors concering both the image preparation (Photoshop's save for web and even general profile handling before that) and the way the Image Magic resizing process is setup. I know probably the person with the most experience on this, (hope you can chime in here Horst) What are your experiences with profile/color consistency when using Image Magick for resizing? ![]()
