What Is A Putter Variable ND Filter

A Variable ND (Neutral Density) filter is a type of adjustable filter used in photography and videography. By rotating the filter with a putter, you can change the transparency of the filter, thereby controlling the amount of light entering the camera lens.

why you needs a putter Variable ND filter？

Photographers love the shallow focus they get when shooting with a wide aperture lens. The bokeh created by a wide aperture can make videos look more professional and cinematic.

However, when shooting in bright daylight, it is often nearly impossible to shoot wide open without overexposing the image. If you have a putter variable nd filter, though, it's easy to do.

The putter variable nd filter allows you to reduce the amount of light in a scene by 2 to 8 stops. It is essentially a way to control exposure, working in conjunction with shutter speed, aperture, and ISO.

The most common use case for the Putter variable ND filter is in video, where you can rotate the filter and smoothly adjust the exposure as the light changes, such as panning from a darker area to a brighter area, always keeping the same aperture and the same depth of field.

However, in many cases, getting the "correct" exposure is not the only way to shoot. You can use the Putter Variable ND to change the light and dark changes of the scene to get a dramatic effect.

Tips for buying putter Variable ND filter

A high-quality variable ND filter should be made from premium optical glass with multi-coatings to reduce reflections, glare, and protect the filter. It should offer a wide and consistent range of light reduction, avoiding the "X-pattern" seen in lower-quality filters. The filter's build should be durable, with a smooth rotating mechanism for precise adjustments and a slim profile to prevent vignetting on wide-angle lenses, ensuring your images remain sharp and free from color casts or distortion.
