Power in Area Light, for example Power 2.0, or for LEM light.
Sun Power I suggest leave 3.0 - it gives more warm in room.

how do you change that light setup?
I will explain from second part:
- Sun Photons need to be a bit stronger the usually it means when photons from Sun hit dark floor you lose power of photons
here without Power:

here with Power 5:

You can add Power for all sources of light. But I suggest use maximum value 3.0 no more.
For Area Lights/LEM in windows better is to keep default 1.0 but if you have difficulty to bright up interiors you can use Power for all lights.


btw. in this example I turned OFF all lights except Sun Light (to vivid effect)


And here all lights ON:
- Sphere GI outside (actually it gives not so much photons but this is for reflection effect)
- Area Lights in Windows (default)
- Sun Light with Power 3.0

This system is used everywhere. Only what is missing: good surfacing :wink:


One more render: beautiful spectrum of interpolated photons

Hello, and thank you Janusz.

nobody talks about QLWF plugin anymore. Your scene doesn't use it. Do we have to forget it ?

Personally I do not use. You can try it but correction of gamma is so strong (it must be that according idea of linear compensation) and brings difficulty in rendering.

I noticed also when I open Archinteriors or another scene I see common setting is Reinhard no LWF (In Kray this is call blending). Anyway I am fan of rendering with a little gamma "washed" rendering ...more important for me is quality of surfaces, AA and blur because rest I do in post process - anyway people who use LWF also use later post process :lol:
Her you can see my last RAW renders:

It is basic blending Gamma 2.2 with Exponential 6.0 - 50%. The RAW render has maybe too much contrast (Bugatti) - but I wanted that. Also light is very weak becouse only HDRi+ little Sun.
I think If I would use LWF it will be much worst: too strong colors, big contrast and this will make troubles in post process.

Also is very important: I use Color Tool Node to correct textures. Almost all textures need to be corrected: less brightness, more contrast, very often saturation 20-40% more or less depends from needs even HUE.

I tried many times LWF because this is really correct way but in rendering department it is difficult to handle so I "compensate" it is post process.
