34 Promote Control 3.15 User Manual Rev 23

The first number indicates beginning of the focus stacking range, while the second number indicates the

end.

Scroll to the second number and use your "Up" and "Down" keys to pre-focus the camera where you

want the focus stacking to end. On Canon cameras you may use the rear LCD Live View to verify the

focus positions. With a Nikon camera, please use your lens' distance scale to do the same. You should

end up with a display similar to this:

+000...+025

The "Frames" setting shows how many images will be taken as a result. You may reduce the number of

frames if you feel that the resulting focus stacking sequence will be too gradual.

You can optionally change the "Exposure" setting from "<On Camera>" to "<HDR>". This will allow

taking not one but multiple images per every focus stacking stop. Promote Control will use settings from

the High Dynamic Range mode screen for the HDR. See High Dynamic Range Mode section for more

information on HDR settings. To switch to the High Dynamic Range mode faster, hold "Left" button and

press "Mode" until High Dynamic Range mode is shown.

When done, press "Start" button on the Promote Control. If you switched to High Dynamic Range mode in

the above step, you will need to return to Focus Stacking mode before pressing "Start". Now Promote

Control will drive your camera lens focus back to the start point, then start refocusing your lens and take

pictures as it goes along. The resulting image set may be merged into a single, focus-stacked image in a

software application of choice. See Focus Stacking Software Applications section for more

information on picking a software package.

Important To Know

1. If you operate your camera lens focus ring after setting focusing range on the Promote Control, you

need to change "Step" to "None/Reset" and repeat the set up process as described above. Failing to

do so will result in incorrect focus range tracking.

2. If you change your "Step" size setting on the Promote Control after setting focusing range on the

Promote Control, the focusing range settings will revert to 0, and the set up process will have to be

repeated as described above.

7.7 Video Control

If your Canon digital SLR camera supports video, you can use your Promote Control to start/stop your

video recording, as well as control exposure parameters - both before video is recorded or while it is

recording. Promote Control can also automatically time video clips of certain length, and stop recording

after a preset period of time has elapsed. At this time this feature is only available with Canon digital SLR

cameras (Nikon digital SLR cameras disable the rear LCD Live View and HDMI output while tethered via

USB, and therefore do not allow framing the video).
