Product Description
The 80A color conversion filter transforms the color of the ambient light entering the lens by adding blue to the overall exposure. This helps match the scene to your film's white balance.
The Hoya 80A filter is helpful when:
-
You are using daylight-balanced film (5500°K) and the light source is 3200°K. This commonly occurs indoors.
-
You are shooting with daylight-balanced film at night.
