Formatt Hitech HT100CTC81B overview

  • 1Description

The 81 Series of filters control the bluish coloration that affects daylight film. They can also remove excessive blue from the effects of electronic flash. Good for general scenics when the photographer wishes to remove the bluish cast from open shade or just add warmth to the photograph, with an 81EF having the greatest effect.

Whereas the 81 Series of filters creates a feeling of warmth, the 82 Series creates a feeling of coolness.

Hitech resin filters are made from lightweight, optical resin and are 4 x 4" (100 x 100mm) x 1.5mm thick.
