As a regular contributor to the photography education site Digital Photography School, I share a variety of tips and tutorials for those who are new to photography as well as seasoned veterans. It’s a way for me to combine two of my passions, teaching and photography, in a way that reaches far more people than I ever could on my own. All of my columns are available here, but the following are a few of my favorites:
Along with my contributions to DPS, I have created a few videos to help beginners understand the three basic elements of exposure: Shutter, Aperture, and ISO. Understanding how these three work together, and how to control them on your camera, is the first step in unlocking a whole new world of photographic opportunities.
Shutter Speed Explained
Your camera’s shutter is a mechanism that lets light in through the lens, and how long it stays open is known as shutter speed. Knowing what happens when you leave it open for long or short periods of time, and understanding how to control it on your camera, is critical towards understanding how photography works overall.
The aperture on a camera’s lens is an opening that lets light pass through, and the size of the aperture determines how much light will hit your camera’s image sensor (i.e. piece of digital film). A wide aperture and a small aperture both have radically different effects on the pictures you can produce, and this video explains the concept along with a few examples as well.
ISO is a critical element of exposure, but it is often misunderstood. This video clarifies some of the confusion and offers some examples to illustrate the concept for those who are still a bit unsure about it.
