e Center-weighted average 
metering
The metering is weighted at the center 
and then averaged for the entire scene.
With multiple spot meter readings, you can see the relative exposure levels of multiple areas in the picture and set the exposure to obtain the desired result.
1Set the metering mode to  r spot metering.
2Press the < I> button. (8 )
  Aim the spot metering circle over the area where you want a 
relative exposure reading, then press the < I> button.

The camera automatically sets the shutter speed and aperture to suit 
the subject’s brightness. This is called Program AE.

shutter button completely.
  If “30 ” shutter speed and the maximum aperture 
blink, it indicates underexposure.
Increase the ISO speed or use flash.
  If the “ 8000” shutter speed and the minimum 
aperture blink, it indicates overexposure.
Lower the ISO speed or use an ND filter (sold 
separately) to re duce the amount of  light entering 
the lens.

In this mode, you set the shutter speed and the camera automatically 
sets the aperture to obtain the correct exposure matching the 
brightness of the subject. This is called shutter-priority AE. 
A faster shutter speed can freeze th e action or moving subject. Or a 
slower shutter speed can create a bl urred effect, giving the impression 
of motion.

 If the maximum aperture blinks, it indicates 
underexposure.
Turn the < 6> dial to set a slower shutter 
speed until the aperture stops blinking or 
set a higher ISO speed.
  If the minimum aperture blinks, it indicates 
overexposure.
Turn the < 6> dial to set a faster shutter 
speed until the aperture stops blinking or 
set a lower ISO speed.

The shutter speeds from “ 8000” to “4” indicate the denominator of the 
fractional shutter speed. For example, “...

In this mode, you set the desired aperture and the camera sets the 
shutter speed automatically to obtain the correct exposure suiting the 
subject brightness. This is called aperture-priority AE. 
A higher f/number (smaller aperture hole) will make more of the 
foreground and background fall within acceptable focus. On the other 
hand, a lower f/number (larger aperture hole) will make less of the 
foreground and background fall within acceptable focus.

In this mode, you set both the shutter speed and aperture as desired. To 
determine the exposure, refer to the exposure level indicator in the 
viewfinder or use a commercially-available handheld exposure meter. 
This method is called manual exposure.

Exposure compensation is used to alter the standard exposure set by 
the camera. You can make the image look brighter (increased 
exposure) or darker (decreased ex posure). You can set the exposure 
compensation up to ±3 stops in 1/3-stop increments.

By changing the shutter speed or aperture automatically, the camera 
brackets the exposure up to ±3 stops in 1/3-stop increments for three 
successive shots. This is called AEB.
