The Hoya W10 filter is helpful when:

• You are using tungsten-balanced film and want to capture natural colors during the daytime instead of the heavy blue cast the film will create.
• You are shooting tungsten-balanced film indoors with 5500° Kelvin light sources like flashed or studio strobes.
• W10 is not as strong as the W12, so it will produce a slightly warmer look when used with standard tungsten-balance film.

HOYA Multicoat (HMC) filters are recommended for enhancing the performance of today's multicoated lenses. These popular filters minimize reflection, reduce flare and ghosting, and result in over 97% average light transmission.
