Warm-up Filters

Warm up filters are typically used for correcting the light blue cast in the shadows under a blue sky. They also also absorbs UV radiation and hence it provides better sharpness and haze reduction. With colour films and/or developing processes that generally yield results that are cool, these filters will redress the balance and provide a more warm and likeable result. With these filters, skin tones in particular will be rendered in a more natural and pleasing way.
