Hi!
I usually work with Max and Vray and both have a camera exposure options.
I can change ISO, fstops,... and I can use them like a real camera parameters.
But when I try to use these knowledges inside Houdini they don't work in the same way, or not at all. (for example, F-stop determines blurriness of depth of field effects, but not the aperture of diaphragm and the level of the brightness).

How do you make correctly exposed renders using Mantra?
or saying in other words, what should I do to match them with a real footage brightness without changing every light in the scene?
Thanks!
