Heliopan #25 Light Red Filter (Bay 104mm) |
|
The Bay 104 #25 Light Red Filter from Heliopan is designed to build strong contrast in black and white photography. The filter will make skies look more dramatic and give a tonal difference between foliage and the flowers. Infrared images can also be enhanced by the filter giving a moonlight effect. The color blue and green are completely absorbed, which will make them darker and increasingly show more contrast. The red color will even cut and remove haze from a black and white image. Exposures should be increased by 3 stops, because of the 8x filter factor.
