After talking so much about exposure and the controls you can use to, em.. well… control it, I thought I’d bring up some info that can help bring all the control info together.
As a solid base for demonstration, I chose to display and discuss a bit about a rule know as the “Sunny Day 16” rule. I guess that this rule is known to film photographers, and is of little use nowadays when all the cameras have built in light meters. But we can explore this rule and learn something about exposure from it.
The rule is simple: on a sunny day, set your aperture to f/16 and set your shutter speed to be as close to the ISO setting as possible. (There! All the three exposure controls in one coherent sentence. Pat on the back!). This is where this rule got its name – Sunny day 16. Image by Stefan Mendelsohn.[Read More…]
