Cokin, a company founded by French photographer Jean Coquin in 1978, is famous for inventing the square filter system for cameras. With such a long-standing pedigree in the filter space and kicking off the square format altogether, I was delighted to get hold of a Cokin NX filter holder and Cokin Nuances Infrared 720 (89B) filter to put to the test.
The beauty of a square filter system is that it enables you to quickly and easily stack and swap a variety of different filters, such as the Cokin Nuances Graduated ND filters that I also tested recently. I took the Cokin Nuances Infrared 720 (89B) out to thoroughly test it on some landscapes and compared them to images taken with and without the filters in place.
