Enhanced Color Infrared Filter
The Enhanced Color IR filter transmits a bit more of the visible red light than our standard filter, it’s 50% pass frequency is 665nm and its most similar equivalent is the Wratten 70 gelatin filter.
Since it passes more visible red light the resulting IR images have more color in them. Not only is the color in the sky, it’s also in the foliage as well. Both can be manipulated in Photoshop to produce a very unique result.
