  1. camera exposure

    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). http://www.sidefx.com/docs/houdini13.0/nodes/obj/cam 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!
