4.3 Indicator Lights

IQ2 Series digital backs feature two main red and green LEDs located below

the bottom left corner of the screen. When the IQ2 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 IQ2 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 IQ2 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 IQ2 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 IQ2 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.
