8.5 Long Exposure Noise Reduction Operation

If your camera supports Long Exposure Noise Reduction function, it affects camera operating timing.

When this feature is On and your camera is taking images with shutter speeds slower than approximately

1 second, a special noise reducing procedure will be applied. This procedure will take approximately as

long as the preceding exposure time.

Using this feature may interfere with exposure timing. However, your Promote Control is capable of

determining when your camera has Long Exposure Noise Reduction turned on. In that case, your

Promote Control will wait after taking every image that is longer than 1 second. A message on the

Promote Control screen will read: "Long Exposure NR", and a time remaining to complete this step will

be displayed.

Promote Control will attempt to check if camera has its Long Exposure Noise Reduction setting enabled,

and will reflect it in its own "LeNR" setting found on the bottom of the Promote Control screen. Note that

you may disable Promote Control from doing this check, and you will then have to manually control the

"LeNR" setting on the Promote Control. See Setup Menu section for more information on the Enable

camera settings check/sync Setup setting.

If the "LeNR" setting displays "N/A", it means the "Long Exposure Noise Reduction" functionality is not

available with the current mode and settings. If the Promote Control "LeNR" feature reads "N/A",

please make sure your camera has Long Exposure Noise Reduction feature disabled, as it

may affect correct Promote Control functionality.

8.6 Using Remote Sensors

Promote Control can start taking pictures by receiving commands from optional external remote sensors.

This allow image captures activated by a manual remote signal, noise, light, crossing an invisible path, or

other remote activation events.

Promote Control is compatible with any type of sensor that can trigger shutter of a Canon EOS Rebel

digital camera. The Promote Control Remote Sensor Port is a 2.5mm stereo plug with a pin out equal to

that of a Canon EOS Rebel remote shutter release port. Please consult Promote Systems Support for

more information on connecting your custom devices to the Promote Control Remote Sensor Port.

Use the following workflow with remote sensors:

1. Connect Promote Control to the camera as described in Connections section.

2. Connect the remote sensor to the remote sensor port described in Interfaces section. No further

setup is required.

3. If the remote sensor activation is expected to take a long time, increase or disable the Auto Power-

Off option in the Setup Menu to prevent Promote Control from turning itself off before the

sensor can activate.
