Noise in images
During shooting at slow shutter speeds of 30 or more
seconds, noise may appear on-screen or the image
may be overly bright in the top left part of the screen.
These phenomena are caused when current is
generated in those sections of the CCD that are not
normally exposed to light, resulting in a rise in
temperature in the CCD or CCD drive circuit. This can
also occur when shooting with a high ISO setting in an
environment exposed to heat. The NOISE
REDUCTION function helps reduce this noise.
Bulb shooting
You can take a picture with a bulb exposure time in which the shutter stays open as
long as you hold down the shutter button (up to 8 minutes). Set the shutter speed to
[bulb] in the M mode. Bulb shooting can also be done using the optional remote
control (RM-1).

TIPS
The picture looks blurred.
J The possibility of camera shake spoiling your picture increases greatly when
you take a picture at slow shutter speed. Use a monopod or tripod to
stabilize the camera.
To change the EV step interval:
J In the menu, set the EV step interval to 1/3EV, 1/2EV or 1EV.
