Backstory: I've been using darktable for a number of years and have recently been reprocessing some older images to take advantage of the improved noise reduction options. A couple of years ago I noticed that older images using the split-toning effect displayed with incorrect colors (saturation cranked way up). Opening the darkroom mode and tweaking the split toning settings could get back to the way it looked previously. I assumed the parameters of the split toning module had been upgraded in a way that broke backwards compatibility and didn't worry too much about it, since at the time I had no reason to reprocess those images. I mention this in case it may be relevant. Present Issue (current git master) For reprocessing one of these old images I was looking at a snapshot of a PNG exported at the time of original processing, so that I could match the color and tone. So far, so good. Then I exported the image to PNG and noticed that the result looked very different---much less saturated. Even with the split toning saturation turned all the way up, I cannot match the saturation of the original image or of the present RAW. I've tried every 'rendering intent' with the same result. I assumed it was some kind of colorspace problem and tried to reproduce the effect with the colorize and other modules, but I could not. It seems to be a problem specific to split toning, but it is a subtle effect, so I may be mistaken. For the record, I am using color management. ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to [email protected]
