FILM SPEED METERING THE AMOUNT OF LIGHT Film Speed Film speed is indicated on the back of film packages. ISO 100, ISO 200, and ISO 400 are the most common. High-speed film (ISO 400), as implied by its name, is for taking photos of fast-moving subjects in action shots, for example. However, there are also other advantages. With high-speed film, such as ISO 400, it is possible to take pictures in lower light. And the distance covered by the flash will be greater. Generally, the higher the film speed, the grainier the picture. With this camera, we recommend the use of "DX" film cartridges: ISO 25 ~ 3200. In the case of non-DX-coded film, the camera will automatically be set to film speed ISO 32. Light Metering Light metering can measure the brightness of the framed subject in various ways. This camera employs three metering systems: (1) ESP light metering, (2) center-weighted average light metering, and (3) spot metering. You can select the light metering system most suitable to the conditions. The camera also uses TTL (through-the-lens) light metering to automatically measure the light that enters the lens. This lets you get very accurate light readings that are unaffected by changes in the distance between the subject and the camera. Fuzzy Logic ESP (Electro-Selective Pattern) Light Metering ESP light metering measures the brightness of the central portion and peripheral portion of the frame separately in order to determine the proper exposure. The calculation program used is based on programmed data to properly compensate for backlighting. ESP light metering is used automatically when in the Full-Auto mode. 51

FILM SPEED
METERING THE AMOUNT OF LIGHT
Film Speed
Film speed is indicated on the back of film
packages. ISO 100, ISO 200, and ISO 400
are the most common. High-speed film (ISO
400), as implied by its name, is for taking
photos of fast-moving subjects in action
shots, for example. However, there are also
other advantages. With high-speed film,
such as ISO 400, it is possible to take
pictures in lower light. And the distance
covered by the flash will be greater.
Generally, the higher the film speed, the
grainier the picture.
With this camera, we recommend the use of
"DX" film cartridges: ISO 25 ~ 3200. In the
case of non-DX-coded film, the camera will
automatically be set to film speed ISO 32.
Light Metering
Light metering can measure the brightness
of the framed subject in various ways. This
camera employs three metering systems: (1)
ESP light metering, (2) center-weighted
average light metering, and (3) spot
metering. You can select the light metering
system most suitable to the conditions. The
camera also uses TTL (through-the-lens)
light metering to automatically measure the
light that enters the lens. This lets you get
very accurate light readings that are
unaffected by changes in the distance
between the subject and the camera.

ESP light metering measures the brightness
of the central portion and peripheral portion
of the frame separately in order to determine
the proper exposure. The calculation
program used is based on programmed data
to properly compensate for backlighting.
ESP light metering is used automatically
when in the Full-Auto mode.
