ISO Bracket captures a series of images while changing ISO between captures. Use it when you want to compare noise, highlight protection, minimum acceptable shutter speed, or body performance across ISO values.

Before you start

ISO Bracket requires Manual exposure mode. Manual mode keeps shutter speed and aperture fixed while the workflow changes ISO. This makes exposure brightness change with ISO unless other camera settings, lighting, or flash behavior compensate for it.

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

Choosing values

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

Selected ISO values are saved with the current profile.

Running ISO Bracket

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

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

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 ISO bracket files

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