photographic exposure वाक्य

But while Braque and Picasso favored still lifes and portraits, mostly in drab colors, the Futurists chose to show cars, trains, cyclists, dancers and crowds in bright colors, repeating a form's outlines like multiple photographic exposures ( or ancient Egyptian and Etruscan designs ) to create a sense of movement.
The FWHM of the point spread function ( loosely called seeing disc diameter or " " seeing " " ) is a reference to the best possible angular resolution which can be achieved by an optical telescope in a long photographic exposure, and corresponds to the FWHM of the fuzzy blob seen when observing a point-like source ( such as a star ) through the atmosphere.
