Our camera is just an instrument. It’s what happens in our mind that makes a great photograph. When we understand the tools, we focus on the artistry. Sometimes we fall for the scam that we can just fix it later and so we fail to expose well and never get that truly magical light. Today’s tip takes on a simple truth about exposure in the camera. I call it, Doubles and Halves!
Photographic exposure and simple math are one on the same. Don’t run away, it’s more elegant than it seems. F5.6 to F8 doubles or halves your light. ISO 200 to 400 doubles or halves. So does 1/50th to 1/100th and so on. Ditto for Zones and Exposure Value and Ratios. They are all connected. All tools to manage and understand the Stops (flow) of light. Just doubles and halves.
Understanding these terms helps you nail the light and focus on the vision. This video from the first chapters of my EXposed series explains in simple terms. EXposed also covers deeper aspects, so if you love understanding light, check it out here.
