When asked about exposure control, most photographers trot out the Exposure Triangle in an attempt to explain how to control exposure in camera. I think that it is a useless concept because it doesn't show the differences between aperture and shutter speed. ISO is not even a factor in exposure. In this video I explain the shortcomings of the Exposure Triangle and put forward my simple and logical alternative for teaching and learning exposure and brightness control in Mirrorless cameras and DSLR's.
