Summary

[edit]
Description Comparison of Cokin filters for IR effect on Illford SFX200. This shot has stacked Circular Polarizer (160) and the Red-Blue Varicolor Polarizer (171). I've found that stacking these two can create a total red washout to the eye, but i have no idea what wavelength range this produces. Technical bits aside, the IR effect is muted, especially in areas that are not in direct sunlight. I believe the vignetting is caused by the circular polarizer.
