Product Description

Product Description:Gradient filter, also known as [GND filter], is one of the most important filters in photographic art creation. It can be divided into gradient color filter and gradient diffuser. In terms of gradient form, it can be divided into soft gradient and hard gradient. " That is, the transition range is larger, and vice versa, that is, the transition range is smaller, both of which need to be selected according to the characteristics of the creation. The full name of the gradient filter is the gradient neutral grayscale filter, and they have almost no effect on the color cast or white balance of the image. The gear design is mainly based on the difference in brightness between an overly bright sky and a darker ground, making exposure easier and photo brightness looking more natural. Filters are made of high-quality optical glass without compromising color reproduction.

Gradient mirrors can be divided into screw-in and plug-in designs. Since the gradient lens with the plug-in design is easier to change the angle, and the proportion of the gradient can be changed by shifting up and down, it is very popular with photography enthusiasts. In addition to the gradient filter, the plug-in design filter system also provides ND, star mirror and other averaging filters. The plug-in design gradient filter can be fixed in front of the lens with a bracket, and the bracket can be used with multiple filters at the same time.
