Build a three- or five-frame exposure bracket at a fixed aperture and record the complete sequence after shooting. HOW IT WORKS 1. Open Helper and tap Bracket. Enter the subject, lighting, aperture and anchor shutter. 2. Choose three or five frames and inspect the exposure offsets and available roll slots. 3. After taking the shots, explicitly confirm the completed bracket to add its frames to the active roll. Roll logs, the exposure helper, focus, filters and reciprocity references remain available. WHAT TO KNOW Calculated shutter times may not be supported exactly by your camera. Long exposures can require film-specific reciprocity correction. This does not trigger a camera or meter a scene. The complete bracket needs available frame slots; existing frames are preserved. iPhone and iPad.
