Release the shutter.
In bulb and live bulb modes, keep the shutter button pressed. The exposure ends when the
button is released.
In time and live time modes, press the shutter button all the way down once to start the
exposure and again to end it.
During live time photography, you can refresh the preview by pressing the shutter button
halfway.
The exposure ends automatically when the time selected for [Bulb/Time Timer] is reached.
g“Configuring BULB/TIME/COMP Settings (BULB/TIME/COMP Settings)” (P.269)
[Noise Reduction] is applied after shooting. The display shows the time remaining until
the process is complete. You can choose the conditions under which [Noise Reduction] is
performed. g“Long Exposure Noise Reduction Options (Noise Reduction)” (P.174)
Some limitations apply to the choice of ISO sensitivity settings available.
Bulb photography is used in place of live bulb photography when multiple exposure, keystone
compensation, or fisheye correction is in effect.
Time photography is used in place of live time photography when multiple exposure, keystone
compensation, or fisheye correction is in effect.
During shooting, there are limits on the settings for the following functions.
Sequential shooting, self-timer shooting, time lapse shooting, AE bracket shooting, flash
bracketing, focus bracketing, Focus Stacking, etc.
Depending on camera settings, the temperature, and the situation, you may notice noise or bright
spots in the monitor. These may sometimes appear in pictures even when [Noise Reduction] is
enabled. g“Long Exposure Noise Reduction Options (Noise Reduction)” (P.174)
Starry sky AF can be used for shots of the night sky. g“Choosing a focus mode (KAF Mode /
nAF Mode)” (P.100), “Changing the settings of Starry Sky AF (Starry Sky AF Setting)” (P.119)
Display brightness can be adjusted during bulb/time photography. g“Configuring BULB/TIME/
COMP Settings (BULB/TIME/COMP Settings)” (P.269)
In mode B (bulb), you can adjust focus manually while the exposure is in progress. You can take
pictures using techniques such as putting the subject out of focus during exposure or focusing at
the end of exposure. g“Configuring BULB/TIME/COMP Settings (BULB/TIME/COMP Settings)”
(P.269)
Noise
While shooting at slow shutter speeds, noise may appear on screen. These phenomena occur
when the temperature rises in the image sensor or image sensor internal drive circuit, causing
current to be generated in those sections of the image sensor that are not normally exposed
to light. This can also occur when shooting with a high ISO setting in a high-temperature
environment. To reduce this noise, the camera activates the noise reduction function. g“Long
Exposure Noise Reduction Options (Noise Reduction)” (P.174)
