Even when your arm is stretched out as far as possible, it can be a struggle to get a finger or thumb on the shutter of your iPhone camera to take that selfie. An update to the app Camera+ trips the shutter with a smile.

Version 10 of Camera+, one of the more popular apps for iPhone photographers, announced new features this week with improvements that take full advantage of iOS 11.

“One of the additions we are most proud of is the new Smile mode,” Pedro Cuenca wrote on the Camera+ blog. “It works like the stabilizer, but for smiles. Now you can simply smile, and the photo will be shot. (It) works for the back camera too, and for any number of people. Just point the camera at them and tell a funny joke.”

Camera+ now allows shooting in the new HEIF format, a smaller file size with supposed jpegs quality so more photos can be stored on your phone.

The app also provides full depth support, which will give iPhone photographs the ability to makes color or tonal changes to a background to make a foreground subject standout. App developers did not have access to depth information under iOS 10.

Camera+ also made changes to its interface, including a shooting bar that gives a user quicker access to features on both the app and the native camera features, like Portrait and Macro modes.

A (+) button gives users access to settings previously buried in a menu.

Camera+ is available for a $2.99 download for iPhone and $4.99 for iPad in the App Store. A version will fewer features is also available for free download.
