Cokin Filter Systems are made for photo and video cameras. The filter is placed in front of the camera lens to modulate the quantity of light that reach the sensor in order to modify colours, contrast, saturation, shutter-speed, depth-of-field and such parameters. Using a filter is a different philosophy than using a software. Filters are used "live", during the shooting, for instant results. Even if post-processing is part of the workflow, we believe that using a filter is a mean to express creativity when you shoot. Placing a filter in front of a lens takes no more than 3 seconds. You obtain instant results that you can share without having to spend hours of post-processing.
