For controlling exposure, the exposure options menu contains two options: "AE Lock" and "Bulb/Time."

Autoexposure (AE) lock produces a series of pictures using the same shutter speed, aperture, exposure, sensitivity and white balance.

This can be used when taking photographs that will later be joined into a single image after transfer to a computer.

Option	Description
OFF	Restores normal exposure and white balancle.
ON	First picture taken after On is selected sets shutter speed, aperture, exposure compensation, sensitivity and white balance for all subsequent pictures. Flash turns off while AE lock is in effect.
Reset	Clears existing exposure settings. First picture taken after this option is selected sets shutter speed, aperture, exposure compensation, sensitivity and white balance for all subsequent pictures.

In mode M, shutter speed can be set for long exposures of up to ten minutes.

"Bulb release" or "Timed release" can be selected.

Option	Description
Bulb release	Shutter will remain open as long as shutter-release button is held down, to a maximum of ten minutes.
Timed release	Shutter will open when shutter-release button is pressed and will remain open until specified exposure time has elapsed or the shutter-release button is pressed again.
