It should be quite easy to measure. Take a series of pictures with different exposure time t, using a constant light source. Then the input to the system will be linear, because the number of photons that will hit the sensor is proportional to E and t. This will give measure points of the imaging system, which can be used to create a calibration profile. ...

Per this thread, this effect could be because of the way the Profiled Denoise module: The “profiled denoise” module and the way how the image preview is generated. To make it fast the preview only takes “part” of the image. IRC in the full image view, the image is not even demosaic? Once you zoom in a bit you will notice, that it gets unsharp like the ...

This question describes what may be a couple different problems: when I change anything (exposure, contrast, etc) temporarily the preview I get from darkroom is what resembles to the jpg photo This may be related to the setting, GUI Options | "don't use embedded preview JPEG but half-size raw", which talberg describes. Make sure it is enabled. It may be ...
