Aperture Bracket

Capture selected apertures in one workflow run

Aperture Bracket captures a series of images while changing aperture between captures. Use it for depth-of-field comparisons, lens sharpness testing, and aperture stack planning.

Exposure mode

Aperture Bracket can run in Manual or Aperture Priority exposure mode.

In Manual mode, shutter speed and ISO stay under your current camera settings while the workflow changes aperture. This is useful when you want to see both depth-of-field and brightness changes from aperture alone.

In Aperture Priority mode, the body can adjust shutter speed to preserve metered brightness while the workflow changes aperture. This is useful when you want a more consistent brightness comparison across f-stops.

Auto ISO, exposure compensation, metering, lighting changes, flash behavior, and body-side shutter limits can still affect the final exposure. Check the camera settings before starting the run.

Before you start

Aperture Bracket can start when the camera is connected, the connection is not changing, capture is ready, aperture is settable, at least one selected aperture value is available, and no other workflow is running.

Some lens and body combinations can make aperture unavailable or read-only in certain modes. If the aperture list is empty or Start is disabled, check the connected lens, exposure mode, and camera state.

Choosing values

Available lists the aperture values reported by the connected body. Move the values you want into Selected. The workflow captures the Selected values in the order shown.

Selected aperture values are saved with the current profile.

Running Aperture Bracket

  1. Connect the camera.
  2. Set exposure mode to Manual or Aperture Priority.
  3. Open Workflows/Bracket/Aperture Bracket.
  4. Move the aperture values you want into Selected.
  5. Select Start.

The app shoot/status area reports progress as each aperture value is set and captured. When the final capture has finished, the workflow restores the original aperture when possible and reports Bracket complete.

Aperture stack planning

An aperture stack is a useful way to compare how a lens renders a subject at different f-stops. Use Aperture Priority when you want the body to maintain metered brightness by adjusting shutter speed as the aperture changes. Use Manual when you want the comparison to include the brightness change caused by the aperture change.

Cancelling

Select Cancel to stop the remaining queued captures. If a capture has already started, the camera may still need to finish the active capture or transfer before cancellation is complete.

Saving Aperture bracket files

Use a Path template with @GRP when all images from one Aperture bracket run should land in the same generated folder. Open the Bracket help page for a full bracket workflow overview and Path grouping example.
