In this episode of Ask David, I answer a question about how light meters function. Not in terms of the interface, but how they see the world. The answer might surprise you: they all have really flat world views. The answer here is a general conceptual understanding with some explanation of different modes. Matrix and averaging, as a practical matter for understanding light meters, work about the same way. Understanding that light meters see the world as a flat gray will help with next week's video where we talk about the zone system.
