Photography Snapshot: Exposure Triangle

November 12, 2012Helene McLaughlin

In the last couple months my Photography Snapshot series has focused on the theory of light and how it behaves as it created images in an optical system. I’m planning to shift my focus now from the theoretical side of photography to the practical components of taking magnificent photos. This snapshot will focus on creating the perfectly exposed image and the three most important elements in determining exposure. So pick up your camera, its time to play.

Photography Snapshot: The Power of Lenses

September 14, 2012Helen Barker

This article is the third in a series teaching the basics of photography. We started by learning about the properties of light and how an image is created, we also learned how a lens bends light to focus individual rays into a single bright image. This lesson we are going to finish learning the scientific theory of lenses and how to use lenses for magnification in addition to brightness.

Photography Snapshot: Light Bends and Focuses

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. In this Snapshot we will discuss the difference between reflection and refraction, how a lens focuses light and how a lense’s focal length will impact an image.

Photography Snapshot: Why is Light Important?

Over the next few weeks, I’m going to share a number of lessons dealing with the essentials of photography, some of the science behind the images, and products that are likely to make your pictures easier or better. This first lesson will deal with the basic properties of light and the most basic ways to capture that light. Future lessons will talk about the exposure triangle: aperture, shutter speed and ISO.
