A primer on exposure values (EVs)
- Now, whilst many V-Ray users are no strangers to using real world camera parameters such as f-number, shutter speed and film speed to control exposure in a render, what some of us may not be quite so au fait with are the exposure values, or EVs for short, that the new physical camera uses by default. Well, an exposure value is really just a quick and easy way in which we can describe the amount of light that is present in a given environment. Once measured and then exposure value established, that number can be used to dial in our exposure settings, and so give us a theoretically best exposure for the shot that we are wanting to take. Interestingly, though, an exposure value doesn't actually give us an exact recipe or specific set of exposure parameters that need to be used in order to achieve it. In fact, any specific exposure value can be arrived at by means of a variety of shutter speed, aperture, and ISO or film speed combinations. Although, for the information purists among us,…
