Matrix Metering system An advanced exposure metering system using a multi-segment sensor and computer. Available in the F5 and other Nikon SLR cameras. 3D Color Matrix Metering: With Multi-Meter Finder DP-30 and D-type Nikkor lenses, 3D Color Matrix Metering is automatically activated with the F5. With the classic techniques of evaluating for 18% reflectance, factors such as brightness and contrast are primarily used to determine exposure. In addition, it is essential to evaluate each scene's esthetic factors such as color to get the best exposure. The shadows of a building, cool with blue. A panoramic landscape with a bright blue sky. Or a winter scene covered with pristine white snow. The F5's 3D Color Matrix Meter evaluates not only each scene's brightness and contrast but, using a special Red-Green-Blue (RGB) sensor, it also evaluates the scene's colors. Then its powerful microcomputer and database together guide it to unequaled exposure control. Monitor Pre-flash(es) When performing Automatic Balanced Fill-Flash with TTL Multi Sensor, the Speedlight fires a series of scarcely visible preflashes to enable the camera's computer to pre-analyze the scene. The TTL Multi Sensor inside the camera body reads the amount of reflected light, then the camera's microcomputer determines the area of the TTL sensor to be used for flash output control and adjusts the flash output level. The Monitor Pre-flashes are visible but not recognizable. Rear-Curtain Sync Flash fires an instant before the second (rear) curtain of the focal plane shutter begins to move. When slow shutter speeds are used, this feature can create a blur effect from the ambient light, i.e., a flowing-light patterns following a moving subject with subject movement frozen at the end of the light flow. (See "Front-Curtain Sync".) Release-Priority for autofocus Shutter can be released anytime (i.e., even when subject is not in focus). Helps you avoid missed opportunities when you are not concerned with absolute focusing precision. With the F5 camera body, Release-Priority is given to Continuous Servo AF mode while Focus-Priority is given to Single Servo AF. Using Custom Setting, however, you can change the priority to Focus-Priority Continuous Servo AF or Release-Priority Single Servo AF. 160

Matrix Metering system
An advanced exposure metering system using a multi-segment
sensor and computer. Available in the F5 and other Nikon SLR
cameras.
3D Color Matrix Metering:
With Multi-Meter Finder DP-30
and D-type Nikkor lenses, 3D Color Matrix Metering is auto-
matically activated with the F5. With the classic techniques of
evaluating for 18% reflectance, factors such as brightness
and contrast are primarily used to determine exposure. In
addition, it is essential to evaluate each scene’s esthetic
factors such as color to get the best exposure. The shadows
of a building, cool with blue. A panoramic landscape with a
bright blue sky. Or a winter scene covered with pristine white
snow. The F5’s 3D Color Matrix Meter evaluates not only
each scene’s brightness and contrast but, using a special
Red-Green-Blue (RGB) sensor, it also evaluates the scene’s
colors. Then its powerful microcomputer and database
together guide it to unequaled exposure control.
Monitor Pre-flash(es)
When performing Automatic Balanced Fill-Flash with TTL Multi
Sensor, the Speedlight fires a series of scarcely visible pre-
flashes to enable the camera’s computer to pre-analyze the
scene. The TTL Multi Sensor inside the camera body reads the
amount of reflected light, then the camera’s microcomputer
determines the area of the TTL sensor to be used for flash
output control and adjusts the flash output level. The Monitor
Pre-flashes are visible but not recognizable.
Rear-Curtain Sync
Flash fires an instant before the second (rear) curtain of the focal
plane shutter begins to move. When slow shutter speeds are
used, this feature can create a blur effect from the ambient light,
i.e., a flowing-light patterns following a moving subject with
subject movement frozen at the end of the light flow. (See
“Front-Curtain Sync”.)
Release-Priority for autofocus
Shutter can be released anytime (i.e., even when subject is not
in focus). Helps you avoid missed opportunities when you are
not concerned with absolute focusing precision.
With the F5 camera body, Release-Priority is given to
Continuous Servo AF mode while Focus-Priority is given to
Single Servo AF. Using Custom Setting, however, you can
change the priority to Focus-Priority Continuous Servo AF or
Release-Priority Single Servo AF.
