22 Promote Control 3.15 User Manual Rev 23

Creating a High Dynamic Range image from series of bracketed images requires an optional third party

software program. Many software applications are available to create High Dynamic Range images in

manual or batch modes. See High Dynamic Range Software Applications section for more

information.

Promote Control automatically calculates High Dynamic Range (or HDR) image sequences for you

depending on a number of easy to use settings. Promote Control varies the camera shutter speed to

achieve different exposures on each image taken. The aperture always remains the same because this is

important in obtaining the correct HDR image sequences. This procedure is also known as "exposure

bracketing". The Promote Control allows you to completely and remotely control exposure bracketing

parameters without manually operating the camera controls.

By default, the Promote Control takes a "middle" shutter speed as a start, and then takes the requested

number of pictures with the shutter speed stepped under and over the "middle" exposure, thereby

creating an increasingly brighter sequence of images. You can optionally choose to build the sequence

starting from the longest or shortest exposure, allowing for better shadow or highlight control

respectively. Refer to HDR Start Point Setup setting description for more details.

Usage

1. Switch your Promote Control to the "High Dynamic Range" mode.

2. Mount your camera on a tripod to avoid camera movement or shake between or during image

capture.

3. Make sure your camera is connected and set up .

4. Disable automatic focus on your camera.

5. If your camera has "Automatic" setting for ISO control, make sure to disable it and set your camera

ISO to a fixed setting. Failure to do so will allow camera to compensate for bracketing changes

introduced by Promote Control, and this will negate the effect of bracketing.

6. Use your camera exposure metering, or other exposure metering methods, to determine start

exposure parameters. Normally this will be a shutter speed/aperture/ISO speed combination that

yields a well exposed image. As a rule of thumb, set the exposure compensation to zero and pick

automatically metered exposure parameters from your camera exposure meter. You will be able to

easily change it later if required.

Alternatively, you may set your camera to "Manual" exposure mode, and manually adjust exposure

settings until the exposure compensation indicator shows zero. Consult your camera manual for the

details of exposure metering in "Manual" exposure mode.

7. After measuring the exposure set your camera to Manual exposure mode unless it's already set.

8. Enter the exposure from the step 3 using the "Mid" setting. This setting can also read "Lo Exposure"

or "Hi Exposure", depending on the choice for the HDR Start Point in the Setup Menu . In those
