hdri and exposure control

[Dave Buckley]

next question for today .. . i think it will be the last today also, feel like i'm having a 'thicko' day

 

i've got some hdri map in the environment slot of my material.

 

however it isn't having any effect.

 

my scene is a studio environment lit with two sky portals, backbody shaders assigned to both to control kelvin temps.

 

i want the hdri to be visible in reflections not for lighting

 

do i have to boost the hdri when using exposure controls.

 

exposure is mr photographic set to a more night time-like exposure due to the nature of the light setup

 

my lighting is exactly how i want it
