Exposure compensation allows for more control over the final image and can automatically control how the camera sees light. In this video, George goes over the three types of exposure compensation used in V-Ray and applies it to the scene.
- [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.
