In optics, defocus is the aberration in which an image is simply out of focus. This aberration is familiar to anyone who has used a camera, videocamera, microscope, telescope, or binoculars. Optically, defocus refers to a translation of the focus along the optical axis away from the detection surface.
Photos and videos were backed up in full resolution and in their original formats. This feature almost meant that lower-quality versions of photos could be cached on the device rather than the full-size images, potentially saving significant storage space on models with limited storage availability.

While Photo Stream uses the iCloud servers, usage does not come out of the user's iCloud storage allowance. This is also true for iTunes Match music content, even for music that is not sold in the iTunes Store and which gets uploaded into iCloud storage, it does not count against the user's allowance. Other apps can optionally integrate app ...
The Photos app can now manually set the time, date, and location of a photo. The app also allows the user to view information about the photo such as the camera used to take the photo and the photo's file size.
The iPhone 3GS's camera app features a slider which allows users to switch between capturing photos and recording videos, a tap-to-focus feature which allows users to tap on an area of the camera image to auto-focus on, 5x digital zoom (iOS 4 or later), autofocus and auto exposure lock when holding an area down (iOS 5 or later), and gridlines ...
The App Store received its first major design overhaul since iOS 7 to focus on editorial content and daily highlights. A "Files" file manager app allowed access to files stored locally on-device and in iCloud and other cloud services. With this addition, users could also for the first time save files downloaded using Safari right on their ...
In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to uncorrected spherical aberration.A soft focus lens deliberately introduces spherical aberration which blurs fine texture in the image while retaining sharp edges across areas of high contrast; it is not the same as an out-of-focus image, and the effect cannot be achieved simply by defocusing a ...
The lens can focus on a plane in the background and the diopter on a foreground. A split diopter does not create real deep focus, only the illusion of this. What distinguishes it from traditional deep focus is that there is not continuous depth of field from foreground to background; the space between the two sharp objects is out of focus.
