The Ultra Color infrared conversion (590nm) The 590nm infrared conversion lets more visible light in, producing the most vibrant colors. Leaves are golden yellow, and skies are bright blue. B+W contrast is lower than the deeper infrared filters.
When to get this IR conversion: This conversion is good for vibrant color IR landscapes, allowing the most flexibility in post processing. Also a good choice for portraits. The shallow IR shows less veins than the deeper IR filters while still creating a dreamy look. May not be as sharp as the deeper filters do to increased chromatic aberration. Cameras with this infrared conversion can also add the 665, 720, and 850 filter over the lens making it the most flexible infrared conversion option if you don’t want to shoot normal color.
