All pictures are recorded as RAW data and compressed
using a lossless compression algorithm that does not
degrade image quality. Reported file sizes are approximate.
The actual file size will vary depending on the subject,
shooting conditions, and shooting mode.
SELECTING THE METERING MODE
The camera has three advanced metering modes. To select the metering mode,
depress and hold the Metering Mode Button, then turn the “C”-dial to select the
desired mode and display it on the LCD panel. Then, release the metering
button. The selected metering mode is now set.
8 SEGMENT METERING
The camera measures the brightness of the
scene by independently measuring each
segment of the focusing screen and analyzing
the correct exposure for the main subject under
any lighting situation.
Even under strong back lighting or complex
lighting situations, the camera will give you the
orrect exposure. c
AVERAGE METERING
The camera will measure the average brightness
of the entire scene with additional emphasis on
the center area. It will determine the most
suitable exposure with respect to lighting
conditions.
CENTER AREA METERING
The camera will measure the brightness only inside of the circle as shown in the
viewfinder. This mode is suitable when you wish to set exposure for a portion of the
scene and ignore the influence of rest of the scene.
