Since we are dealing with real camera properties, shouldn't "shutter speed" parameter be available?
Setting exposure to i.e. +10 to get a descent lit interior doesn't seem "physical", or is there something I'm missing?

use fstop (exposition time) and ISO (film sensitivity) to control how much light is coming in.

Does the ISO even works like in real-life ? Because in such case it should be left were it is, eg.100 or less.

I am able to adjust light properly with f-stop and exposure, but yeah, I woudn't have exposure value of that much in actual photographing either. But would that even make sense here ? It's still CG

That's how I control lighting right now but it would be nice to have control over the shutter speed. Don't know how much of coding does it require to implement this feature but I hope it will be available in a future release.

Don't f-stop, ISO and Exposure do the exact same thing in Octane?

In a real camera, these not only affect the exposure of the image, they also affect other parameters.
f-stop: Gives shallow (e.g. f/1.4) or wide depth of field (e.g. f/16)
ISO: Raises the amount of noise or grain
Exposure time: Affects the amount of motion blur

Motion blur isn't implemented yet, but I assume we will get a control for it once it's available.
