Cokin P121F - Specificaties

Designed so that absolutely no color from the entire visible spectrum prevails, the neutral density filters can be used in many different contexts, depending on which type is used : uniform shading (square) or graduated shading (rectangular).\n\nUniform ND filters reduce the quantity of light that reaches the sensor – or the film – increasing the exposure time. These filters have 3 main practical applications:\n- emphasizing the flow of movement,\n- reducing the depth of field,\n- avoiding overexposure.\n\nGraduated ND filters are used to reduce the contrast difference of a composition. They allow for a well-balanced image; they are the filters most used by landscape photographers to yield both harmonious skies and detailed foregrounds at once.\n\nWith these filters, images which are impossible to obtain in digital post-processing can be created. The neutral density filters are also currently used in filmmaking and video to maintain a constant shutter speed for example.
