[br][br]Portrait mode started as one of the scene modes you typically find on a digital camera, but now the feature has been adapted to smartphone photography. While both the portrait mode on a digital camera and the portrait mode on a smartphone may share the same name, they vary drastically in how the image is taken. [br][br]When first offered as a photo mode on digital cameras, portrait mode helped novice photographers take better portraits by adjusting the camera settings. The aperture, or the opening in the lens, widens to blur the background. A blurred background draws the eye to the subject and eliminates distractions in the background, so wide apertures are popular for professionally shot portraits. Over time, additional optimization was added in, such as improving the processing to make faces even clearer by eliminating red eye and adjusting the autofocus. [br][br]A smartphone camera, however, cannot adjust those settings to take a better portrait. For starters, the aperture on most smartphone cameras is fixed, so you can't actually change it. Even on the few models that allow for an adjustable aperture, however, the lens and sensor inside a smartphone camera are too small to create the blur that DSLRs or mirrorless cameras are capable of capturing.
