Cokin BPW400 Wide Angle System is 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 colors, 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. Moreover, the price of a set of filters is nothing compared to expensive software requiring well-equipped computers to run, especially for video editing. With filters, you’ll never have any problem of compatibility with the last generation RAW that is not yet recognized by your software. Using a filter will take the same time on a 10Mp or 60Mp camera… Which may not be the case on a computer, where heavy files can slow-down the whole workflow. Photography happens when you shoot, not when you sit behind your computer.
