Understanding the Exposure controls

In the real world, photographers use exposure to control the brightness of their photographic images. This means they can create images that not only look technically correct, but that are also able to evoke a response from their viewers. In chapter 2 of this course we looked at how the V-Ray Sun and Sky combined to create a physically accurate daylight simulation. As they are designed to create the same level of illumination as the actual sun and sky, they are, in layman's terms, extremely bright.

In fact, if we were to render in V-Ray without the use of Exposure control, we would get an image that was essentially a whiteout. In fact, let's go into our Options Editor we can show you just what we mean by that statement. So let's come into our Camera rollout. Down here you can see we have an Exposure checkbox. If we disable that and then take a test render--let's just dismiss our options dialog-- you'll see exactly what we mean. In this instance, as you can see...
