70 Shooting - Selecting Particular Effects
Manually Setting the Shutter Speed and Aperture
You can manually set the shutter speed and aperture to achieve a particular effect.
This is convenient for shooting fireworks and other images where it is difficult to
set the correct exposure automatically.
1
Turn the shooting mode dial to .
The shutter speed and aperture settings appears on the
LCD monitor if it is on.

Select a shutter speed using B or A on
the multicontroller.

on the multicontroller.

Shoot the image.
When you press the shutter button halfway, a number indicating the
difference between the standard exposure* and the selected exposure
appears on the LCD monitor. If the difference is more than ±2 steps, “-2”
or “+2” appears in red.
* The standard exposure is calculated by the AE function according to the selected metering method.
The exposure compensation, AE lock, FE lock, flash exposure compensation, AEB
and ISO speed (AUTO) settings cannot be adjusted in this mode.
If you wish to change the exposure, adjust the shutter speed using B or A on the
multicontroller, or adjust the aperture using C or D on the multicontroller.
When you select a fast shutter speed or shoot a subject in a dark place, set the
flash to
(Red-Eye Reduction, Flash On) or (Flash On) so that the LCD monitor
does not darken and you can check the image before shooting.
For the correlation between aperture value and shutter speed, see page 67.
