This {pnstop}-stop, 100 x 100mm Haida Red Diamond ND 4.5 Filter is an ND filter with a 32,000x filter factor that provides a 15-stop exposure reduction. It is compatible with the Haida 100 or 100-Pro Filter Holder, and its 4.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

Haida Red Diamond filters are constructed from shock-resistant optical glass. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes 10 layers of antireflective nano coatings. An additional 10 scratch-resistant hydrophobic coatings further protect a Haida Red Diamond filter's substrate and result in an improved beading effect when its surfaces come in contact with water or oil, allowing for more efficient cleaning. Additionally, Haida Red Diamond filters feature rounded edges for easier placement within a compatible filter holder slot.

A fabric storage pouch for storage and transport is included, as well as a light-blocking gasket. This gasket forms a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in between the filter and the lens behind it.

This filter is compatible with the Haida 100 or 100-Pro Filter Holder.

4.5 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Gradation provides a 15-stop exposure reduction, allowing you to control depth of field and convey movement more easily.
