Illuminates The Lcd Panel During Bulb Exposures - Canon EOS 1D Software Instruction Manual

Illuminates the LCD panel during bulb exposures

After the bulb exposure starts, press the <LCD panel illumination> button to illuminate the
LCD panel until the bulb exposure ends.
Convenient when you want to monitor the elapsed bulb exposure time.
Taking bulb shots for long periods speeds up battery charge depletion and reduces the
number of available shots.
Sets the default settings when the CLEAR button is ON
You can use this function to select the default mode selected when you press the CLEAR
button (QUALITY+WB).
Convenient when you want to instantly switch to frequently-used settings.
Shortened release time lag
Normally, the shutter-release time lag is controlled for stability. This Personal Function
eliminates this control. As a result, the shutter-release time lag can be reduced by as much
as about 20 percent when the aperture needs to be stopped down by no more than 3 stops.
This is effective when a shorter shutter-release time lag is more important than a stable
shutter-release time lag.
Since the difference is in 10-millisecond increments, the time lag may not feel any
shorter.
