The filter is placed in front of the camera lens to modulate the quantity of light that reach the sensor in order to modify colors, contrast, saturation, shutter-speed, depth-of-field and such parameters. These filters are compatable with the Cokin P series. Neutral Density ND filters reduce the amount of light reaching the film without affecting the color. This kit is good for creative photography.
