ios-8
If you haven't yet taken the iOS 8 plunge, you may not know what you're missing. True, iOS 8 has the familiar iOS 7 look and feel, but it's chock full of both new and improved features and functionality. And it's free.
However, if you're toting an iPhone that's getting a little long in the tooth, you might want to consider trading up, as iOS 8 is an option only for owners of the iPhone 4s and later models.
Some of the new features evoke a sigh of relief -- we've been waiting for these, Apple. Others are downright pleasantly surprising and altogether cool.
Here's your guide to the most useful and welcome iOS 8 changes to the Camera and Photo Apps, the new Family Sharing feature and more.

Camera App

The iPhone is the world's most popular camera, and the built-in Camera App is one of the most important apps around. In iOS 8, Apple has introduced several new features, including the ability to adjust exposure separately from the focal point. How does it work?
All you have to do is tap your screen to tell the Camera where to focus. A box pops up with a slider next to it. Slide your finger most anywhere up or down and the exposure will adjust accordingly. Most people who use it will likely attempt to make an image brighter -- or make it darker to better evoke a mood.

The Camera app now lets you set a focus point independent of the sliding exposure control, which can be handy for takings shots of areas with both light and shadow.

The new Timer mode lets you set a timer for 3 or 10 seconds, after which it delivers a burst of 10 photos -- handy for making sure you capture everyone with their eyes open
