Super Blue IR Filter: =td(}3|D Y ' C+ o, P' K: m$ U1 N0 \
This is our 1st patent pending color infrared filter that allows you to capture color IR p_w_picpath with the blue sky straight out of camera without the need for Photoshop channel swaps. Its very unique as it behaves completely differently than all other infrared filters because it actually has 2 distinct pass bands. The super blue filter passes blue light as well as infrared light thus allowing for super saturated blue skies straight in camera! {9F}2 SJ w+ {) s6 N \5 U, f' d0 P
