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 buffer 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 90 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 sec-

onds. 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

exposures 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

reference capture to complete will appear at the bottom of the screen

while the black reference is being captured. This function is performed

automatically.
