Hello,
Sorry for the newbie question but I have a hard getting renders rights, they are over exposed, and if I lower exposure compensation, it affects the realism of the image as well as the textures by making the result too dark and washed out. Or I have to lower down the lights intensity values to a ridiculous level such as 0.0001, which is unusable...
What do I miss there?
Thank you for helping.

Some more information, and some images or a scene to have a check?

Thank you for answering
Here are 2 examples of the same scene, the brighter one is a render at 0 exposure compensation, the corona sun is at only 1.0 intensity. The second example (the darkest) is more towards the mood I'm searching for in my scene, I set the xposure compensation to - 5.5, but look at the result, the color are washed out and dark, especially the sky.

Looks like you are not using a 32-bit file for your sky.

Corona sun has a lot stronger intensity than HDRI on default range. It operates on different exposure level, so you can either bring the sun intensity down, by setting sun intensity multiplier to 0.04, or bring your environment map up, by setting output value of your environment bitmap to about 40 ;)

ok thank you for the tip

Ther is something wrong with the light setup: I can see the sun in the env. but shadow are not following the sun. What kind of setup are you using?? Env(with sun) + Corona sun???

Sorry,
But I finally found that it was the scale of the scene being very small that was causing the issue.
Thank you again for having helped me.
