image contrast problem

[Frenkkk]

I have several problems to create real images with proper contrast, I tried with hdri lighting, with the corona sun and sky, with ies with lights ...
I tried in a thousand ways , but the picture that emerges is always without contrast, and if I try changing the value (exposure , hilight compress, and contrast)  I get burned or flat images.
exposure and hilight compress give me image or too flat or too burned or too dark

i use linear workflow with input / output range of 2.2 and white peaking 180/190.


it is possible that the linear workflow is not set correctly ?

there is a test to see if 3dsmax and corona  are set correctly ?

thanks for help

I´ll admit that I have had the same problems for images to be flat.
Then I bought the Corona Interiors from Evermotion to learn/study from those scenes, they render nicely but they render a looong time.
