Hi, has it a similar way of defining the parameter map DT is using? By playing with the masking contrast and gain in DT one can kind of control what's seen as Blacks, Shadows, What is what may highly depend not only on the absolute luminance but also on the intention of the photograph

Hi, Terry, all - just to announce I have used the ToneEQ on a couple of images now and I start to like it :-) Once you know how it basically works it is fun to use (albeit lots of surprises may lurk in the dark). (Apolgies to István for totally misspelling köszönöm ... never had to write Hu

Hi, István, kösenem, the principle is understood. The ToneEQ-created parameter mask does only indirectly relate the tonal correction to the image areas. The suggested series of parametric masks and related tonal corrections OTOH gives direct control. The ToneEQ-internal mask assigns a certai

Aurelien is a really talented developer that has brought some great features to Darktable including Filmic, Tone Equalizer and I believe Color Calibration. I have been impressed with how he has continued to improve both Filmic and Tone Equalizer to make both of these modules more user friendly and

Tone EQ allows you to apply different exposure compensations to different parts of the image. You can achieve a similar effect by creating several instances of exposure, e.g. one without a mask, so set overall brightness; one with +1EV to lift the shadows, with a parametric mask; and one with -1 EV

Yes, I can see how it is confusing -- the luminance-based mask of the tone equaliser versus the drawn/parametric "alpha-channel" mask used in the darktable generic masking and blending function. Unfortunately both these concepts are commonly referred to as a "mask" in the image processing literatur

Hi, everybody, I had some difficulty to understand what the term "mask" means with the ToneEQ module. Only after watching Aurelien's tutorial (https://www.youtube.com/watch?v=kzACn3l49HM), in particular the part starting at 20:13, I grasped the idea (which is actually not hard to understa
