App of the week:

With Apple’s iPhone 7 and Google’s new Pixel phones putting such an emphasis on powerful camera technology, smartphone photography is more robust than ever. And while phones typically have great built-in 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 single-lens reflex c amera to your eye: The first thing you see is a view through the camera lens, superimposed with many controls and information like the exposure and whether the flash is activated.

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 (great for getting those tricky horizons straight). You can also control the white balance and the ISO setting and bring up a live histogram that shows how saturated the colors in the final photo will be. There are quick-access 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 anti-shake feature, which waits for you to stop moving before it activates the shutter.

T h e a p p c o s t s $ 5 a n d 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 equiva- lent to ProCamera is Camera FV-5. This app also feels like using a single-lens reflex camera, with similar manual control. Camera FV-5 includes features like a live histogram, burst-mode 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 FV-5 has a professional-looking and easy-to-use interface. It costs $4.

To edit that 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.

Its interface is sometimes confusing, and I have found myself ge t t i ng l os t i n i t s menus and submenus, but the app has built-in help and, best of all, is free for both iOS and Android.
