Using a handheld light meter isn’t for everybody, and we occasionally forget to pack a grey card. But there are things that are close enough to middle grey that they can work just as well. Grass is a common subject to meter off in rural areas. But something else you can use is your hand.
Using your hand as a target for spot metering isn’t a new idea, but it’s one that many don’t know about. All modern cameras have built in reflective spot meters, and the hand can be a great way to nail a good exposure. As long as it’s in the same lighting conditions as your subject, you’ll be able to get it spot on every time. This video from Sareesh at Wolfcrow shows us how it’s done.
