Fastcompos are a common form of entertainment at demoparties. Unlike regular compos, fastcompos are announced at the party, usually only a few hours to a day before the deadline, and often have some design or theme limitations. Fastcompos may be held for music, graphics, demos and anything else regular compos are.
The position of the viewer can strongly influence the aesthetics of an image, even if the subject is entirely imaginary and viewed "within the mind's eye". Not only does it influence the elements within the picture, but it also influences the viewer's interpretation of the subject.
For example, if a boy is photographed from above, perhaps from the eye level of an adult, he is diminished in stature. A photograph taken at the child's level would treat him as an equal, and one taken from below could result in an impression of dominance. Therefore, the photographer is choosing the viewer's positioning.
A subject can be rendered more dramatic when it fills the frame. There exists a tendency to perceive things as larger than they actually are, and filling the frame full fills this psychological mechanism. This can be used to eliminate distractions from the background.
In photography, altering the position of the camera can change the image so that the subject has fewer or more distractions with which to compete. This may be achieved by getting closer, moving laterally, tilting, panning, or moving the camera vertically.
