The Kodak 100 x 300mm #16 Yellow-Orange Filter is a general contrast filter, primarily for use with black and white film. This yellow-orange filter noticeably darkens skies, helps to cut through haze, and improves overall contrast. When compared to the yellow #8 and #15 filters, the #16 creates a greater separation between clouds and sky and further lightens yellows and reds within the scene.
The #16 filter has a filter factor of 4 and requires a 2 stop increase in exposure for normal results. Wratten 2 filters are constructed from gelatin for ease of use and consistent performance. When compared to original Wratten filters, Wratten 2 filters are more rigid and durable, easier to handle, and less sensitive to humidity, static cling, and fingerprints.
