Formatt Hitech 100mm Neutral Density Grad.Neutral density (or ND) filters produce a grey neutral tone and are used in photography to reduce light, enabling more control over exposure and depth of field .
The Little Stopper can give increased flexibility with exposure lengths in the lower light at the start and end of the day. This often means that detail and texture can be retained in areas of movement such as the sky and water, while still conveying a sense of time passing.
Formatt Hitech 100 x125mm Blender Grad. Blenders feature an effect transition that occurs over the entire length of the filter. Starting at the top and graduating all the way to the bottom. This allows for a graduated effect across your image without any specific horizon line.
