A neutral density filter, when used with Apple’s premium smartphone, reduces the amount of light entering the camera lens. This allows for greater control over exposure settings, particularly in bright environments. For example, it can facilitate longer shutter speeds to blur motion, or wider apertures to achieve shallow depth of field, even in sunny conditions. The filter is an accessory placed in front of the lens.
The advantage of employing this type of filter on such a device lies in unlocking creative photographic and videographic possibilities that are typically limited by the sensor’s sensitivity and the fixed aperture. Historically, photographers have relied on these filters with professional cameras to overcome similar challenges. Utilizing it offers enhanced versatility, mitigating overexposure and broadening the scope for cinematic effects directly within the mobile platform. This is especially beneficial for capturing footage with intentional motion blur or isolating subjects with a blurred background.
