4.3 Indicator Lights
IQ Series digital backs feature two main red and green LEDs located below
the bottom left corner of the screen. When the IQ back is activated, the green
and red LEDs will ash shortly and a beep will sound to indicate that it is
ready to capture. In general, if the LEDs are not illuminated the camera is
ready.
A red indicates that the IQ back is writing to the storage media, and therefore
the buer has not been emptied. When capturing an image the green LED will
blink rapidly to indicate that the IQ back is busy exposing the CCD or moving
data from the CCD. A continuous green light indicates that the backlight of
the display is dimmed but the camera is still ready to shoot. The IQ back also
has an orange light to indicate that the battery is charging when the back is
connected to a computer via a FireWire or USB connection. (Go to page 84
for more details about charging the battery whilst tethered to a computer).
Additional Red LED
There is an additional red LED indicator located next to the CF card slot (under
the cover). It is assigned to indicate CF card activity only. Do not remove a CF
card from the card slot when this red LED is on. Removing a CF card whilst
the red LED is on can damage the formatting of the card, and images or data
might be lost or corrupted.
4.4 Indicators
Long exposure time indicator: An exposure time indicator will appear on
the IQ screen if the camera is set to expose for more than 2 seconds. The
indicator will count the seconds while the shutter is open. This indicator is
useful for timing long bulb exposures.
Long exposure black reference: In order to capture noise free long expo-
sures Phase One digital backs needs to capture a black reference after
each capture. This black reference requires the same amount of time as the
exposure itself.
A night symbol and a counter counting down the time left for black refer-
ence capture to complete will appear at the bottom of the screen while the
black reference is being captured. This function is performed automatically.
