Nikon cameras deactivate Live View during USB controlled focusing. Therefore a procedure using the lens distance scale is used.
AUTOMATED FOCUS STACKING WITH PROMOTE CONTROL AND NIKON
The Promote Control allows you to automatically create precise focus stacks with single or bracketed exposures. In this tutorial we will create a focus stacked image using the Promote Control and the Nikon D7200:
A tutorial on the workflow with Canon cameras is available here.

Promote Control Setup
- Firmware Version 3.26 or higher
- Connect the UC-E6 cable to the D7200 and the OTG adapter. Connect the Promote Control to the OTG adapter.
- Mount the camera on a tripod, arrange lights and composition.
- Select exposure. In this example: Shutter speed 1.3”, Aperture f/16, ISO 100.
- Turn Live View ON.
- Manually focus on the most distant point of interest. Note the position of the Distance Scale.
- Manually focus to the closest point of interest.
- Turn Promote Control ON.
- Live View on Nikon will automatically turn OFF.
- Navigate to the Promote Control Focus Stacking Screen by pressing the “Mode” button.
- Navigate to Step Size using the Left and Right buttons of the four way selector switch. Set value to “Small” by pressing the Up or Down buttons of the four way selector switch.
- Navigate to Range “Start Point” using the Left and Right buttons. Set “Start Point” to +000 pressing the Up or Down buttons.
- Navigate to Range “End Point” using the Left and Right buttons. Press the Up or Down buttons to advance the focus until the Distant Scale indicates the most distant point of interest determined in Step 3. In our example the resulting End Point is +051.
- Optional: adjust the number of shots (Frames) to be taken.
- Press the Start Button. The lens will automatically return to the start position and the shooting sequence will begin.
- The Promote Control beeps once the sequence finishes.
- Merge the image stack using photo-editing software of choice.
- In steps 3 and 9, we recommend to go slightly beyond start and end points to ensure the entire focus range is covered in your sequence of images. Any extra frames can be deleted later.
- You can also set up your Promote Control to bracket exposures for HDR focus stacking.
