Hi,
In LuxRender 1.7, in order to get linear response of the image gray levels to increase in light intensity, I had to set Exposure Mode to "Absolute" as follows:
bpy.data.cameras['Right Camera'].luxrender_camera.exposure_mode == 'absolute'
Should I do a similar thing in LuxCore2 in order to get linear response to light intensity?
If the answer is Yes, then how?
Many thanks,
Igal

Re: Exposure Mode in LuxCore2
If you use linear tone mapping with a scale of 1.0 and gamma 1.0, you will obtain the untouched values out of the rendering (if you save in .exr format). Is that what are you looking for ?igall2 wrote: ↑Mon Apr 30, 2018 2:50 pm In LuxRender 1.7, in order to get linear response of the image gray levels to increase in light intensity, I had to set Exposure Mode to "Absolute" as follows:

You can also enable the RGB AOV in the render layer settings, if you want the raw data in addition to the usual tonemapped image.
