Aperture Priority- is a setting on some cameras that allows the user to choose a specific

ASA/ISO/Film Speed-
Film speed is the measure of a
photographic film's sensitivity to
light, determined by
sensitometry and measured on
various numerical scales, the most recent being the
ISO system. Film speed is used in the
exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect:
lighting, film speed,
f-number (aperture size), and
shutter speed (exposure time).
