[darktable-dev] What is the gamma.c IOP ?

Hi Jo ! Thanks for your answer. So this doesn't explain why the global colorpicker readings change depending on the display ICC profile, nor why using a log encoding between -2.5 and 2.5 EV, the grey gets remapped to L = 77 instead of 50. I believe there is a gamma correction where it doesn't

It does appear that cmake requires rawspeed. I can only presume that darktable requires it. cmake lets u know that it wants rawspeed/ anyway someone created the cmake scripts. Anyway someone created the error messages. It was not cmake that created them. On 11/2/18 8:41 AM, Sturm Flut wrote:

Dear list, I guess this can also depend a lot on the hardware and the specific X.Org/Mesa/GTK/driver version combinations. I've been using darktable on a 4K display with Arch Linux running on a Ryzen 1600X for one and a half years and there haven't been any noticeable lags, neither with the old

heya, it used to do the gamma in the olden days. now it just does what you observed: convert to uint8 for display and any marshalling of data at the end of the pipeline in gui mode can take place here. it's certainly not applying gamma. i suppose we could delete these old gamma lut table lines of
