Thanks Ondra for your comment!
I checked albedo problem - I did not even know about it before! So after correcting the walls to the level of 0.8, this is the effect when applied only on walls:
This is an effect when applied to the window and door framing as well:
What I love about it is that suddenly there is a bunch more of details in the scene. But in the same time I am starting to wonder if the scene is not too dark. I tried to rise up the exposure instead:
Bedroom (after lowering white level to 0,8 and rising exposure from 1 to 2):
And here I have a question - should I always keep every white element in the scene below 1? For example the vase on the right and the mattress of the bed are now 1.0 and the floor now has also 100% of brightness
*.
Last view:
* and test regading having the radiators and floor also in 0,8 level. However the rendering time went way higher....
So if I am correct, every pure white material must have albedo in the level of 0,8, right? But then, should I also always have less than 100% of the brightness of the texture materials? Or can I leave those as they are (by the default 100%)?
What can be improved more? I was thinking about learning how to make levels of the reflection in Corona (like vRay has few specular layers + dirt). I wonder if this could help even more. For example I still don't know how to do an effect like for exampel fingerprints on a surface (in additional to normal diffuse and reflection map) - so how to add fingerprints layer. In vRay I would use Specular Layers. Same with the vRay dirt. How to add those things in Corona?
