By reducing visual complexity abstraction increases perceptual efficiency allowing us to recognize objects, evaluate movement and orient ourselves in space with great rapidity.
The abstract qualities in art are those which are independent of a work's resemblance to external reality.
In daily life most visual information is redundant.
In the case of photographic images it has been calculated that this redundancy may be as high as 90%.
The surfaces of objects are sometimes so abstracted that they are cleansed of their natural texture, for instance, the reflections that would be expected to be observed.
Vermeer's abstraction may have in part been inspired by the generalized image of a camera obscura.
