Paint the sky in provocative colors! The COKIN Fluo gradient filters feature explosive colors. You will benefit from their saturation whenever you want to contrast them with particularly bright colors in your subjects. A field of flowers, a brightly colored yellow house, your model in a fluorescent pink tracksuit... the list is endless. The COKIN Fluo gradient filters do not do subtlety. They prefer the fire of exuberant passion over romantic sentiments. Give them Amazons with blood-red lips and extravagant clothing, surfers in bright Bermuda shorts.
