Blender - HDR makes objects too bright I started to use blender 3 weeks ago and I am currently trying to do an outdoor scene.
I wanted to use an hdr image fot lighting, as blender guru does -> https://www.youtube.com/watch?v=fI_FMa-8w50&amp;t=117s

But all of my objects keep over exposing, even if I a set the values of the math converter almost to zero

This is the scene with a sun lamp (strenght 1)


This is the same scene but using one of blender gurus free hdr and with the sun lamp hided


I believe I`m using filmic color correctly:


I also tried with simple objects (like blender gurus tutorial) and ended up with the same wrong result :(

Hope someone could help!
Thanks (:
You can change the brightness of the environment texture in the world section by modifiying the Strength value for the HDR.
