Heliopan 72mm KB15 (80A) Color Conversion Glass Filter

The slightly denser Heliopan 72mm KB15 (80A) Color Conversion Glass Filter is recommended for daylight color reversal film with artificial light from the popular 60-100W halogen bulbs commonly used in lights aimed at the ceiling. With weaker incandescent bulbs, there will again be that pleasant warm tone for moody interior photographs.

Let's say you're at a family gathering and you've brought your camera and want to take some photos of this once-a-year gathering. You have traditional daylight balanced film but find yourself in a room filled with table lamps. If left unfiltered, your photos will turn out yellowish. Under certain circumstances, perhaps a nice effect but not flattering in terms of skin tones or what our eyes are used to seeing or expecting. Enter the 80A filter!...
