11. To stop the sequence before it is completed, or if you used the value of "Infinite" for the "Frames" in

the "Time-Lapse" mode screen, press and hold the "Power" button. Promote Control will then return

to the mode settings screen and await further instructions.

Taking images in "Time-Lapse HDR" mode may take a long time to complete. Make sure to use a fresh

set of batteries in both Promote Control and your camera and use a large memory card. You may also

consider using an optional AC adapter for the Promote Control and/or your camera.

8.2 Advanced Bulb Ramping

If you feel limited by the original Bulb Ramping mode , you may decide to try Advanced Bulb Ramping.

It greatly extends exposure range limitations and allows for seamless bulb ramping from broad daylight

straight to night time, often with little to no manual intervention during a sequence.

Initial Setup

Use the following workflow to set up your Promote Control for Advanced Bulb Ramping:

1. Make sure your Promote Control is set up as described in the Promote Control Setup section.

2. Enable Advanced Bulb Ramping in Promote Control Setup menu .

3. Set "Lowest Auto ISO for adv. bulb ramping" Setup setting to the lowest ISO setting available with

your camera. On most cameras this would be ISO 100, while some other cameras may go as low as

ISO 50 (often referred to as "Lo"). Some cameras may have ISO 200 as their minimum. Consult your

camera user manual for details.

4. Set "Highest Auto ISO for adv. bulb ramping" Setup setting to the highest ISO setting your camera

can offer without introducing too much image noise. With most modern cameras, ISO 3200 would be

a good choice, while some on advanced, low noise cameras such as Canon EOS 5D Mark III an ISO

of 6400 or even higher may still be usable. Note that the wider the ISO range you set between

"Lowest" and "Highest", the more flexibility Promote Control can offer in Advanced Bulb Ramping

mode.

5. As always with Bulb-related modes, make sure you calibrate "Shutter close delay".
