2. DEPTH OF FIELD With the iPhone 7 Plus, Apple introduced the dual-lens camera to create a greater sense of depth of field in portraits. Combined with Portrait mode introduced with iOS 10.1, you can finally get a desirable blurred background with people, pet or other portraiture. Earlier iPhone owners can use apps to simulate the effect, including Camera+, Snapseed, Leonardo, Big Lens and Tadaa SLR.
3. FLASH AND HDR Two other settings that can be used manually are the flash (tap the lightning bolt) and high dynamic range (tap HDR), which combines several images of the same scene taken at different exposures into a single well-exposed photo. This is especially effective on landscapes when one area is bright and another is shaded.
