Kray: range 1.7 exposure 1.7. Photon power 1.1 render preset High.
correct? need more light? how can I not create too lit areas if the increased power of the sun?
Thanks for your important recommendations

Washing renders...looks raytracing
Power in Kray You have totaly big... I thing good idea is make this parametr maximum 0.2-0.3, and recurse 20;
Forget lights from outside (use only blue background for reflection) rest light from Area light outside room (around 1-2 m behinde windows , 30 % smaller then windows , inverse dist 2 , colour blue + Shader Power around 20-50)
Of coarse this will make dark render ...but next You must put on ceiling around 4 small area light per room (orange or beige colour) with big Power Shader around 100-150.
Exponential 2.0. .. this is my sugestions.
btw : if You use sun Turn On Power shader for this (colour beige) around 6-10.
Background view must have Raytracing Shader and "Unseen by radiosity"
