Florescent lighting has characteristics that
affect color rendition. This color shift is not usually visual to the human eye
but will cause adverse effects on film.
When shooting under "daylight" florescents your pictures will have a purplish
tone. Hoya's FL-D filter corrects and restores a normal color balance.
In industrial situations you might encounter "warm white" florescents which will
give a greenish tone, requiring Hoya's FL-W corrective filter.
Both filters are available in coated and multi coated (stronger flare
prevention) versions and all popular sizes.
Features:

General:
As their names suggest, these filters use HOYA coloured glass. They are used for
colour correction of different light sources when using colour film, or for
controlling contrast with Black & White film. Colour correction filters are
important, as colour films do not have the flexibility of the human eye to
automatically adjust to different situations. Black & White films register
colours as shades of grey and the rendition of each colour in a scene is
important, so filters can be used to control this. The colour of the glass used
in all these filters is carefully controlled and to reduce the possibility of
colour shift over a period of time, such high quality filters are coated or
multicoated on both sides. This maintains the desired effect and gives a long
service life.
