720nm Infrared

The Standard IR Filter (720nm) This is the tried and true classic infrared conversion. It allows for good color for false color, and good contrast for black and white. This is equivalent to the Hoya R72 and Wratten 89b.
When to get this infrared conversion: This IR conversion is good if you are interested in shooting some mild color and black and white. This filter produces the traditional dark blue skies and can also be processed for color. While not as high contrast as the 850nm, some people prefer this filter over the 850nm for B+W work, as it allows a little more color for B+W processing. Cameras with this conversion can also add the 850nm filter over the lens.
