Kodak 3 x 3" #15 Deep Yellow Optical Wratten 2 Filter is an industry-standard filter that just got better. With the same spectral response and color as current Wratten Gelatin Filters, Kodak Wratten 2 Optical Filters offer several improvements.
Slightly stronger than the #12, this filter is commonly used for an even more noticeable increase in contrast with black and white films. Especially useful for clear contrast between blue sky with clouds and foreground. It is also suitable for landscapes and nature scenes.
