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 of color, brushes, and varnish;

• Customized 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.
