Arriving at the best exposure for a photo is part science and part art. Technology is on your side, but sometimes, to get the image you want, you have to override your camera's controls. In Photography Foundations: Exposure, Ben Long helps photographers expand their artistic options by giving them a deeper understanding of shutter speed, aperture, ISO, and all the other critical aspects of exposure. Part one of this two-part series explores the basics: concepts such as tone, dynamic range, and reciprocity, and how they relate to the settings on your digital camera. You can learn how to use a light meter and your camera's histogram, adjust the brightness and detail in your photos, prevent blur, and understand exactly how the auto modes work. By the end of the course, you'll know how to develop an "exposure strategy" that you can employ in any shooting situation.
