The Intervalometer provides two shooting modes. Interval Mode defines the delay between consecutive photographs. Duration Mode distributes the requested number of shots over a total duration.

ISO Bracketing

ISO Bracketing creates a sequence of images at different ISO values while shutter speed and aperture remain unchanged. The current camera ISO is the center value of the sequence.

Sequence

  • 3 shots
  • 5 shots
  • 9 shots

Bracket step

  • 0.3 EV
  • 0.7 EV
  • 1.0 EV

Minimum bracket ISO is 100. The lower status bar displays the calculated ISO scale in real time, with the center ISO emphasized.

Example: Base ISO 1600, 9 shots, 1.0 EV: 100 → 200 → 400 → 800 → 1600 → 3200 → 6400 → 12800 → 25600.

Sequence timing

  1. Initial autofocus pulse when AF is active.
  2. Wait approximately 0.7 seconds.
  3. Set the next ISO value.
  4. Wait approximately 1.0 second.
  5. Take the photograph.
  6. Wait for capture confirmation.
  7. Wait approximately 2.0 seconds before the next ISO.
  8. Restore the original ISO when the sequence finishes.
