From Cokin's A series
Fluo Graduated Filters are full of explosive colours. Use their saturation every time you want to contrast the bright tones of your subjects. A field of flowers, a bright yellow house, your model in her pink fluo track suit ... the list is endless, COKIN Fluo Graduated Filters are not made for subtlety. They prefer the furnace of excessive passions to the gentler flame of romance. Give them scarlet-mouthed Amazons in extravagant costumes, surfers in rowdy-colored bermudas.
