When editing photos on an iPhone or other iOS device, there are four options for making changes to an image. These options are Crop (which also has rotate and straighten tools); a selection of filters; Adjustments (Light, Color, B&W); and an icon which allows access to apps installed on the user's iPhone.

Apps available will differ depending on the user's own downloads of apps and whether or not the developers have used the iOS APIs allowing access to the camera and Photos.

Those shown are added by the user, and as more are installed with the wider features, these may be added too, by scrolling to the right and tapping, More. This will show the list of apps already available in Photos and any yet to be activated (by toggling a switch).

When one of the apps in the lineup is selected, the image can be edited directly in Photos without needing to switch to the app on the device. However, when editing a photo with an external app, any changes will be applied to the photograph in the library. If iCloud Library is used, the image will be changed on all devices synchronised. The original data is retained and at any time (and on any of the devices) the user may click on Revert for the original image to be available.
