Using a filter is a different approach compared to using 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 in the moment. Placing a filter in front of a lens takes no more than 3 seconds. The outcome is immediate, and you can share it without having to spend hours of post-processing. Photography happens while shooting, not sitting behind a computer.
