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.

In this week’s installment of The Practicing Photographer, Ben Long discusses a fun and challenging photographic subject: wildlife. Whether it’s the birds in your backyard or the buffalo in a nature reserve, wildlife presents an array of photographic challenges—starting with the fact that you don’t have a lot of control over your subject.
This lack of control can lead to an interesting phenomenon: forgetting how to be a photographer. As Ben explains, when you do see an interesting critter, maybe one you haven’t seen before at close range, it’s easy to get so caught up in the experience you neglect those aspects of photography you’ve spent so much time learning—like the need to really work a shot, to move around and experiment with different compositions, focal lengths, and exposure settings.

Cell phone cameras are compact and convenient, and they deliver better image quality than ever.
But what phone cameras aren’t is versatile. For example, their tiny, fixed-focal-length lenses usually can’t focus very close. Several companies have come out with close-up attachments that let you shoot macro photos with a phone. But most have two disadvantages. They can be on the pricey side—$60 and up is a lot to pay for a tiny lens that you may not use all that often. And they tend to be designed for a specific model of phone. If you switch brands or upgrade—or if your family mixes and matches models and brands—you’re out of luck.

Sometimes the world seems so small. With some clever shooting and Adobe Photoshop techniques, you can make it seem even smaller. I’m referring to what’s often called the “tiny world” or “tiny planet” effect, and Ben Long explores it in this week’s two-part installment of The Practicing Photographer.

The zoom lens was patented in 1902, but it wasn’t until the 1970s that zoom lenses became increasingly popular on the 35 mm cameras of that era. The zooms of the ’70s were expensive and often lacked the sharpness and contrast of fixed focal length, or prime, lenses.
Today, thanks to advancements in optical design, zoom lenses are common and often inexpensive. Indeed, the “kit lens” that comes with a typical digital single-lens reflex (DSLR) camera includes a zoom. And the images from a high-quality zoom can stack up against photos taken with a prime lens any day.

There’s a lot of drudgery in digital imaging. Sure, shooting is fun and so is editing and enhancing photos in programs like Lightroom, Aperture, and Photoshop. But then the time comes when you need to send a batch of photos to someone who needs them at a specific size and quality setting. Suddenly, you’re looking at reopening, resizing, and exporting dozens or even hundreds of images.
Doing all that on an image-by-image basis is only slightly less tedious than swinging a pick-axe at a rock pile.
It turns out that computers are pretty good at performing repetitive tasks, and that’s the subject of the latest installment of The Practicing Photographer. This week, Ben Long crawls into one of Photoshop’s nooks and crannies to explore its Image Processor feature.

Digital SLRs are versatile and deliver great image quality, but are big and heavy. Point-and-shoot cameras are compact, but their image quality and versatility are often lacking.
Welcome to an episode of “Goldilocks Buys a Camera”—isn’t there an option that’s just right?
For a growing number of photographers, the answer is a mirrorless camera. This up-and-coming category sits between point-and-shoots and digital SLRs, and Ben Long talks about it in this week’s installment of The Practicing Photographer.

Reflections are something you often don’t want in photography. If you’re shooting through a window, for example, you might attach a polarizing filter to your lens to reduce the glare and reflections of the world behind you (see Chapter 2 in Foundations of Photography: Specialized Lenses).
At other times, though, reflections can add a striking element to a photo. And that’s the subject of this week’s installment of The Practicing Photographer, wherein Ben Long reflects on the value of reflections.
