Photorealist painters tended to imitate photographic images, often omitting or abstracting certain finite detail in order to maintain a consistent overall pictorial design. They often consciously omitted human emotion, political value and narrative elements. The photorealistic style of painting was uniquely tight, precise, and sharply mechanical with an emphasis on mundane everyday imagery, as it was an evolvement from Pop Art.
Hyperrealism, on the other hand, although photographic in essence, can often entail a softer and much more complex focus on the subject depicted, presenting it as a living tangible object. These objects and scenes in Hyperrealism paintings and sculptures are meticulously detailed to create the illusion of a new reality not seen in the original photo.
