Thanks for the explanation of the reasons. As a technician myself I understand it and accept it. Just want to notice, that it would be nice to tell a user that manual enabling of the filmic plugin requires both disabling basic curve (it replaces it) AND adding +1EV. Some notes on enabling scene-b

I need to presume things in order to provide consistent and reasonable workflows from start to end. You get the scene-linear one, based on linear editing with exposure and filmic, and the display-linear one, based on legacy modules and modules order (and base curve), or alternatively, no workflow a

You presume a user chooses one of the approaches and uses it full time. In that case the expose is added automatically. And what if a user mostly uses basecurve approach and time after time wants to make a scene-referred variant? He needs to turn off the basecurve, turn on the filmic module (it is

The required +1 EV exposure boost is now applied automatically in exposure module for new edits if you choose the scene-linear workflow in preferences -> processing -> auto-apply pixel workflow default. Filmic v4 imposes 18% scene to be remapped to 18% display no matter what, resulting in preserva

The change that I see in v. 4.0 is that all of my images appear 1 stop underexposed as compared to the previous version. Earlier I did not need to adjust exposure at all, now I must boost the exposure on all images. David On 2020-06-09 11:46 a.m., Alexander Rabtchevich wrote: Hm, as I underst

Hm, as I understand, if I enable filmic plugin v 4.0 manually, I need to add +1.0EV manually too? That wasn't so with 3.0.  With respect,  Alexander Rabtchevich Aurélien Pierre wrote: Hi, there is a +1 EV added by default in exposure if you enable the scene-referred workflow. I don't unders

Hi, there is a +1 EV added by default in exposure if you enable the scene-referred workflow. I don't understand what you mean. The exposure bias is read in image EXIF, if the bias is 0 EV, then the setting is 0 EV too. Cheers, Aurélien. Le 09/06/2020 à 19:46, Alexander Rabtchevich a écrit : > H
