There isn't much you cannot do with the simplest of cameras nowadays, but even the best of the lot have their limitations when it comes to tricky exposure scenarios. The Promote Control, from Promote Systems, is a remote-control device that enables you to push the so-called limitations of your camera's standard operating parameters, making it possible to capture images that may not have been feasible using your camera's standard exposure capabilities before.
The Promote Control pushes the envelope of your camera's exposure system by enabling you to capture advanced High Dynamic Range (HDR) with the option of incorporating variable bracketing, which allows you to control the tonal characteristics of your images with far more nuance, compared to standard HDR capture.
The Promote Control also enables advanced time-lapse imagery with the most basic DSLRs, including long exposure times and bracketed time exposures that go beyond the 30-second limitations designed into most DSLRs. In these cases, the Promote Control automatically kicks the shutter into Bulb mode to facilitate longer-than-normal exposure needs. User-defined shutter delay with Auto Mirror Lock-up, which allows you to fire the camera shutter hands-free while greatly reducing pre-exposure camera vibration, is also possible with the Promote Control.
The Promote Control is powered by two AA batteries and is fully compatible with digital cameras supporting PTP/MTP camera-industry protocol for controlling camera functions over USB interface, and can be user defined to fit your specific shooting needs.
The Promote Control can be used with the following cameras:
Nikon D3, D3X, D2X, D2Xs, D2H, D2Hs, D200, D300, D700, D40, D40x, D50, D60, D70, D70s, D80, D90
Canon 1D, 1Ds Mk II, 1D Mk III, 1Ds Mk III, 5D, 5D Mk II, 7D, 10D, 20D, 30D, 40D, 50D, 300D, 350D, 400D, 450D, 500D, 1000D
The Promote Control includes a USB connector cable, a USB Firmware Update cable, a case, strap, manual, 2 AA batteries, and a 1-year limited warranty. As for future camera models, the firmware in the Promote Control is designed to be upgraded as new cameras come to market, making it a good long-term investment for serious shooters.
Canon 300D, 350D, 10D, 20D, 5D, 1D/1Ds Mk I and 1D/1Ds Mk II cameras are not supported in HDR mode. Only basic operations such as One-Shot, Time-Lapse and Manual Hold are available on these cameras, and would require a CN3 cable (not included) to be connected. On Canon 5D Mk II and 7D, the longest automatic HDR exposure is limited to 30 seconds due to mechanical Bulb mode activation. A future Promote Control firmware update will prompt to activate Bulb mode manually as required. At this time, using a higher ISO setting is recommended with Canon 5D Mark II and 7D if an exposure longer than 30 seconds is required in HDR mode.
