This cable requires a separately available Promote Control HDR bracketing controller unit.

Using a separate shutter cable with Promote Control offers the following benefits:

• Enables Bulb Ramping mode
• Provides Mirror Lock-Up functionality
• Allows automated exposures longer than 30 seconds
• Ensures faster camera reaction to shutter release, especially in "High Dynamic Range" mode
• Activates "Manual Hold" mode
• Enables arbitrary shutter speeds in "One Shot" and "Time Lapse" modes
• Allows pre-focusing the camera using the Promote Control "Focus" button
• Enables basic Promote Control shutter release functionality even when out of battery power

This shutter cable is compatible with the following cameras:

Canon 400D/XTi, 450D/XSi, 500D/T1i, 550D/T2i, 600D/T3i, 1000D/XS, 1100D/T3, 60D.

NOTE 1: On Canon 60D the longest fully automatic HDR exposure is limited to 30 seconds due to mechanical Bulb mode activation. Promote Control will prompt to activate Bulb mode manually as required.
