Perspective Control in Software
Computer software (such as Photoshop's perspective and distort functions) can be used to control perspective effects in post-production. However, this technique does not allow the recovery of lost resolution in the more distant areas of the subject, or the recovery of lost depth of field due to the angle of the film/sensor plane to the subject. Areas of the image enlarged by these digital techniques may suffer from the visual effects of pixel interpolation, depending on the original image resolution, degree of manipulation, print/display size, and viewing distance.
The effect of using tilt or swing movements is less easily accomplished in post-production. If every part of the image is within the depth of field, it is fairly easy to simulate the effect of shallow depth of field that could be achieved by using tilt or swing; however, if the image has a finite depth of field, post-production cannot simulate the sharpness that could be achieved by using tilt or swing to maximize the region of sharpness.

Famous quotes containing the words perspective and/or control:
“Egoism is the law of perspective as it applies to feelings, according to which what is closest to us appears to be large and weighty, while size and weight decrease with our distance from things.”
—Friedrich Nietzsche (1844–1900)
“For the mother who has opted to stay home, the question remains: Having perfected her role as a caretaker, can she abdicate control to less practiced individuals? Having put all her identity eggs in one basket, can she hand over the basket freely? Having put aside her own ambitions, can she resist imposing them on her children? And having set one example, can she teach another?”
—Melinda M. Marshall (20th century)
