Advanced shooting modes 3 Take the picture. 3 Underexposure Overexposure Optimum exposure All the way down Selecting the right mode for shooting conditions 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. g "Noise reduction" (P. 95) 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). g "Bulb shooting on the remote control" (P. 67)  TIPS The picture looks blurred.
