Most filters are a perfect complement to post-processing. However, the digital world has often made us forget that filters can also be creatively used tools without a computer. Let yourself be inspired by the COKIN magic box: - impressionistic effects like those created with the painter's tubes, brushes, and varnish; - custom rainbows; - black masks and counter-masks for double and multiple exposures (e.g., doppelgänger photos); - romantic symbols, hearts, and cheeky keyholes as picture frames; - psychedelic color effects with colored filter films.
