Top Tip: Photos are best taken in natural light with the sun behind the camera.
In picture 1 the sun light is to harsh meaning that one side of the face is in darkness making it hard to see any markings, the eye or ear.
Picture 2 has been taken too far away, meaning if I was to zoom in on the face it would be a low resolution.
Pictures 3 & 4 show good examples of both close up and far away. All features on the face are shown clearly and if were too zoom in detail of the hair would show.
