Chapter 3: Working with Exposure
Photographers often talk about exposure. But what does exposure mean? In a strict sense, exposure is the amount of light that falls on a light-sensitive surface such as the sensor in your EOS 70D. In the best of worlds, the amount of light will also be the correct amount to create a good exposure that retains details in the highlights and shadows and that has pleasing contrast. In real life, however, exposures cover a broad range. Exposures can be creative, challenging, or just bad. One thing is certain, though — exposure is one of the things you want to get right.
In this chapter, I discuss exposure from a workflow perspective, including goals, exposure modes, the camera’s metering system, and how to evaluate and modify exposure when necessary. The new Multiple exposure and High-dynamic range (HDR) shooting options are also covered.
Regardless of the light, the 70D offers full control to get excellent exposures, with details in the highlights and shadows, as shown here. Exposure: ISO 200, f/5.6, 1/160 second.
