Perspective

Perspective


From the "kampoeng" people sitting at the road blockage at the Hunan Normal University. This shot was of the other hand shot with a small aperture which had caused a deeper depth of field. Its interesting to see what each of them are holding on their lap. Erica was holding her bag, Michelle was holder her water bottle and spectacles which she always take out when taking picture and a camera in Lilyan's hand.



Perspective, in the context of vision and visual perception, is the way in which objects appear to the eye based on their spatial attributes, or their dimensions and the position of the eye relative to the objects.

As objects become more distant, they appear smaller, because their angular diameter (visual angle) decreases. Your view on the world could be thought as an onion where each little layer represents a distance from the eye. As the distance gets larger, the surface area of that layer of onion becomes larger and larger. Because you see things in angles, the angle seen of an object would decrease because the object would take up a smaller amount of surface area at the larger distance. Subsequently, objects that are farther away would seem smaller.
