• Vary the shutter speed to create different exposures. Changing the aperture changes the depth of field in each
exposure and can produce lower-quality results. Changing the ISO or aperture may also cause noise or vignetting
in the image.
• In general, don’t use your camera’s auto-bracket feature, because the exposure changes are usually too small.
• The exposure differences between the photos should be one or two EV (exposure value) steps apart (equivalent to
about one or two f-stops apart).
• Don’t vary the lighting; for instance, don’t use a flash in one exposure but not the next.
• Make sure that nothingismovinginthe scene. Exposure Mergeworks only with differently exposedimagesofthe
