The Tiffen 4x4" Deep Yellow filter 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.

Especially useful for clear contrast between blue sky with clouds and foreground

Enhances landscapes, marine scenes and aerial photography with more dramatic effects than Yellow 8
