When you’re first learning the basics of photography, one of the first things you find out about after dropping out of ‘auto’ is the exposure triangle.
Consisting of shutter speed, aperture and ISO, the exposure triangle is a system that takes into account each of those variables, making exposure adjustments a breeze when you need to change one of the variables for a particular situation (say, freezing motion or achieving a shallow depth of field).
In the above video clip, photographer John Greengo does a great job nailing the basics of this triangle down and offering some nice insight for those folks who are just getting into photography.
Obviously this video isn’t for the veteran or even intermediate photographers out there, but if you’re just starting out, this’ll definitely help you understand how each of those three main variables will affect your images, and how to adjust them appropriately.
