The Heliopan Bay 1 #15 Dark Yellow Glass Filter for Black and White Film is commonly used for a more than noticeable increase in contrast with black and white films.
When a #8 or #12 Yellow isn't enough, the #15 is the next stop. This filter adds a significant amount of contrast to black and white film. And, should this filter not be sufficient, an orange filter is recommended, followed by red, which will provide maximum contrast with black and white film.
