Kodak 3 x 3" #12 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 also offer several improvements.
This filter is commonly used for a 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.
