If you want to take a top-down photo (this simply means taking a photo with the camera above the subject in No angle Allowing you to capture the top surface of the bezel), hold your phone straight down to show two sets of intersecting indicators (+). Set the phone so the yellow and white crosses lie on top of each other.
Crosshair is also available for taking level photos on your iPhone. Simply go to Settings > camera And switch on the network. Hold the phone over the subject for a few seconds and you’ll see the white crosshair and yellow crosshair. Line them up by moving the phone and you will get the image of the level.
