Can someone please explain to me the difference between ‘light exposure’ and ‘light intensity’ on the Env Light > Light tab?

The documentation for this light oddly skips this control http://www.sidefx.com/docs/houdini/nodes/obj/envlight [www.sidefx.com]

Same as other lights.

intensity = 2^exposure

That means if you have intensity 1 and rise exposure to 3 you will get the same result as if you have exposure 0 and intensity 8.

A common workflow is having intensity on 1 (or in <0,1> scale as “scale factor” for animation (on/off/blinking etc…)) and rise up exposure as it better represents f-stops.

Thank you for that. Now it makes sense
