ICloud Photo Library tips
Photos syncs all your images… and your edits
Photos, which started life on iOS and is now on OS X, is Apple’s replacement for iPhoto and Aperture on the Mac. It automatically syncs your photo library to iCloud, so every shot is available on all your devices.
Synchronise your iOS device’s photo library by going to Settings > iCloud > Photos. Make sure the switch beside iCloud Photo Library is turned on and choose whether you want to keep optimised versions on your iOS device, or uncompressed full resolution originals. Either way, the full quality originals are stored in iCloud.
To edit a photo, select it, then tap Edit. On iOS, as well as cropping, applying a filter and automatically enhancing your shot, you can tweak the colour, light and monochrome style. (OS X lets you do more, as you’ll see in the tips on this page.) When you edit an image, Photos just tracks your changes and applies them on the fly. You can roll back to the original at any time by editing again and choosing Revert. Your changes are synced to iCloud and made visible – and revertible – on any of your devices.
By default, your Mac user account’s System Photo Library, which is the only one synced to iCloud, is stored in your Pictures folder. If your startup disk is low on space, you can move the library to another drive and double-click it there to open it in Photos, then click ‘Use as System Photo Library’ in the app’s General preferences.
