The smaller the camera sensor is, then the more of you photograph will be in focus, automatically. That is why DSLRs have much larger sensors than phones. The photographer decides what he will focus on and how much of the scene will be in or out of focus. The phone user will find just about everything is in focus.
The P4P has a relatively large sensor, and therefore cannot show everything in a scene in acceptable focus at f2,8 i.e. wide open, unless you are at 400 feet high and everything is 400 feet or more away from you. Then if you focus on any part of the image it will be acceptably sharp. But P4P lens has an adjustable iris that allows variable aperture of f2,8 to f11. This now gives the aerial photographer the power to adjust how much of his photograph is rendered in focus.
Remember the larger the f number then the more will be in focus, and the smaller the hole (aperture) in the lens will be. This is called depth of focus or depth of field.
It is most noticeable in photographs that contain both near and far objects, and you, as the photographer, must decide which part of the photograph will be in focus. Is the background more important then the foreground or vice versa.
When you have decided this, then select your aperture because this controls how much depth will be in focus, then tap on that part of the image.
Focus peaking will guide you to what is going to be in focus, as it outlines sharp objects in red. |
