The Exposure Triangle consists of Shutter Speed, Aperture and ISO Speed. These topics represent the three variables that create the perfect exposure. These three pieces of the Triangle work together, balancing and compensate for each other. If your camera is in an Auto setting, as one changes, the other two react to keep everything in balance. If you are shooting in manual, you will need to consider the effect changing one of these three settings will have on the other two. Sound complicated? Not really, once you understand how they work together.
Aperture does more than just allow a lot, or a little light to enter the lens. Aperture controls Depth of Field. By using depth of field appropriately, you can create the artful images you desire.
Depth of field is the amount of the picture that is in focus.
Our last technical discussion was about shutter speed to control the freezing of motion or showing the blur of motion. This one will be about aperture. Part 1 will discuss how it works.
The difference Between Fast and Slow Shutter Speed
This post will be a Two Part Post, learning how to understand what effect shutter speed has on your picture.
Part 1 will demonstrate the difference between using a fast shutter speed to “freeze” motion, and a slow shutter speed to show motion.
Part 2 will be a more technical discussion on how to use shutter speeds in the camera and understanding how use the camera’s controls to adjust shutter speed.
