With Apple's iPhone 7 and Google's new Pixel phones putting such an emphasis on powerful camera technology, smartphone photography is more powerful than ever. And while phones typically have great builtin photography apps, many other options can be easier or expand your range. ProCamera is an excellent option for iOS devices. Using this app feels like raising a singlelens reflex camera( 单反相机 ) to your eye. With a few taps on the screen, you can display a grid to help compose a shot properly and a guide to warn if your composition is tilted( 倾斜的 ). You can also control the white balance and bring up a live histogram( 直方图 ) that shows how strong the colours in the final photo will be. There are quickaccess buttons to shoot in video, photo, high dynamic range or other modes and there's even a bar code scanner option. Most impressive is ProCamera's antishake feature, which waits for you to stop moving before it activates the shutter. In the settings menu, you can control most of the app's features and select how much compression is applied to the final saved images. In other words, the app gives users professionallevel control of an image. Because of its complexity, ProCamera takes a while to get used to, and the exact features depend on which iPhone you have. The app costs $5 and some features, like a lowlight mode to help shoot better pictures at night, are upgrades that cost a few dollars each. It's definitely worth it. On Android, one app equivalent to ProCamera is Camera FV5. This app also feels like using a singlelens reflex camera, with similar manual control. Camera FV5 includes features like a live histogram, burstmode shooting, exposure bracketing and timelapse imagery. It also offers choices over the kind of files it saves to your device, and has a comprehensive settings page. Unlike some other Android camera apps, Camera FV5 has a professionallooking and easytouse interface. It costs $4. To edit a perfect portrait or landscape photo, Adobe's software is the choice of professional photographers. There is a version for mobile devices too—Adobe Photoshop Fix—which lets you heal an image's defect, adjust shadow intensity, fix the contrast or add effects. Mastering the features of Photoshop Fix will take time, but your final images don't look too artificial with the application of Photoshop Fix. Its interface is sometimes confusing, but the app has builtin help and, best of all, is free for both iOS and Android. ( )61. What is the author's purpose in writing the passage? A.
