In last week’s installment of The Practicing Photographer, we joined Ben Long at a wildlife preserve, where he photographed buffalo and prairie dogs—and shared some wildlife photography tips along the way. This week, it’s back to the buffalo—but this time, they’re on Ben’s computer screen. Something went wrong during Ben’s wildlife shoot: A lot of his photos were slightly overexposed and washed out. Camera light meters aren’t perfect, and when they don’t read a scene accurately, exposure problems result.
Fortunately, Adobe Photoshop—and other imaging programs, such as Lightroom, Aperture, and iPhoto—can often fix exposure problems. And if you shoot using your camera’s raw mode, you have that much more adjustment flexibility. That’s because raw mode saves every bit of data that your camera’s sensor recorded. By comparison, when you shoot in JPEG mode, your camera’s internal software—in its zeal to create a compact image file—throws away roughly one-third of the information that the sensor recorded.
