Hoya HMC Orange YA3 49mm

The Hoya 49mm YA3 Orange black and white photography contrast filter is used to give strong cloud definition on a blue sky, and cut through UV and blue haze. It's also good for architectural photography as it lightens brickwork. Loses 2 stops of light. HMC (Hoya Multi Coated) protective coatings on both surfaces give enhanced light transmission (97%) and so reduce glare and ghosting. The mount is 4mm deep.
