Use exposure compensation

- [Instructor] When rendering in V-Ray, it's often a good idea to use exposure control. Now, exposure control is very similar to the auto setting on a digital camera. It automatically controls the exposure of the camera, so that you get a good, even image. Now, we can get into exposure control by going into rendering, exposure control. Now, this brings up the environment and effects window. And if we scroll down to the exposure control tab we can pull down and go to V-Ray exposure control. Now, the default mode is photographic. This simulates a camera. So we have shutter speed, the f/stop number. If we dial that down we can get some depth of field effects. We also have ISO and white balance. So this is a great way to mimic real world cameras. Another one to use is to go directly from the V-Ray camera. So you can have those exact controls on the camera, and as you shift cameras or switch between them, these can change. Now, another one, which is actually very simple, is from EV parameter. And what this does is it just controls most of the parameters, and all you have here is an exposure value. So you can basically turn up or turn down the brightness of the scene just by changing this EV value. Now, I'm going to leave it on EV parameter to keep things simple. And as we go through the course we may change it, but for right now understand that V-Ray's exposure control allows for higher variation in lighting, and it will control the camera to reflect an increase or decrease in lighting, so that you get a perfect exposure every time.
