Promote Control

This little pocket-size computer provides valuable services. In practice, in the field, weather conditions can vary greatly. I think especially in the mountains or a country in changeable weather such as Iceland. Therefore, having a tool that is reliable and can stand snow or rain is a major asset.

Moreover, its discreet size allows one to incorporate it to any equipment. The steering of the basic parameters of the camera can also be done by a tablet or a PC, but these have a keyboard/touch screen which are the major weaknesses in difficult weather conditions, without mentioning the transport inconvinience related to the size of these devices.

The Promote Control has all the features required for shooting in remote sites where weather conditions can be harsh, while keeping a pocket size!

 

One shot mode:

When a single image is required, this mode allows one to either keep the camera settings or to choose the exposure time, aperture and sensitivity by the Promote Control for a complete control of the camera. Using the shutter cable, it's possible to select the exposure time in HH:MM:SS which is indispensable for long exposures.

Indeed, the camera bulb mode doesn't give an indication of elapsed time, therefore, the use of the Promote Control allows precise and reproductive exposures without an additional timer. Moreover, its small size allows one to substitute it for traditional wired control while still benefiting from its many functions.

 

HDR mode:

In high-contrast scenes where it is not possible to use a graduated ND filter, the Promote Control allows braketting up to 45 images, a much higher number that in normal use.

The advantage with this system is that it is not necessary to touch the camera to change the shutter speed nor to count in one's head the number of bracketted images when shooting HDR panoramas. In each view, simply operate the device to automatically take parameterized pictures. Very handy in the field.

The 80Mpx image above is the result of 16 sets of 15 exposures in 1/3EV increments. The Promote Control, greatly facilitated this shooting session and its small size allows one to operate it in difficult areas like in this river where I wouldn't go with a laptop!

 

Bulb HDR mode:

This mode is a backup of the HDR presented above. It's useful for the cameras without a USB connection. The steering sequences passes through the bulb mode, but these abilities are limited compared to the HDR mode via USB.

 

Timelapse mode, regular and HDR:

Shooting to compose a timelapse is greatly simplified because the options available with the Promote Control go well beyond the parameters of the camera whatever they are. It is possible to choose the interval, the number of frames and to delay the shooting by setting the delay time in HH:MM:SS. It's also possible to take photos during the intervals, if an unexpected action occured, without stopping the sequence. Furthermore, in case of bad preliminary settings of lighting conditions, exposure is adjustable during the sequence.

But in addition, the function that I particularly like, the HDR timelapse which allows one to succeed in taking difficult shots in high-contrast scenes. Function that is usually not included with the classic intervallometers.

 

Bulb Ramping mode, regular and advanced:

Regular mode is very useful for timelapse of a sunrise or sunset. For larger dynamic range, the advanced mode becomes unavoidable. It is used for the transition from night to day and vice versa.

The bulb ramping mode works by varying the exposure by small increments. The assembled images will produce a video without flickering (rapid changes in exposure). This mode provides a gradual transition from night to day and vice versa. It is also possible to use ND filters, and the Promote Control lets you know when to insert/remove it.

 

Regular focus stacking and HDR:

In macro photography, this technique is widespread because it can increase the depth of field without limit. It is also used in landscape photography where the foreground is very close to the front lens. The Promote Control offers the possibility to pilot the focus mechanism without having to touch the camera during the sequence.

It would be possible to make the focus by hand, but depending on the number of images required (that can go beyond 50), this automated system is a time saver and drastically increases the accuracy. It is possible to activate the HDR function to combine the two techniques. The output images are stacked by PS or other.

 

Manual shutter hold:

This function is identical to that of a basic remote control. Pressing the button and holding it down for the required time of the exposure. Releasing the button stops the shooting. This function requires the support of an additional timer.
