"The 2.1 ND is a real test because at that density you generally see lot’s of variation in colour and consistency. As an extra check I’ve also shot using no filters at all."
John Brawley - Director of Photography
"The main advantage of these filters is their neutrality, especially when using 4 stops (1.2ND) or above.
When I use other IR ND filters I normally have to compensate for a color shift in the grade, but with these I haven’t seen any noticeable color shift. They are by far the best front of camera ND filters I have used."
John Lee - Director of Photography
Manufactured from 4mm-thick, optically flat, scratch-resistant glass, and edged with a metal rim, ProGlass Cine filters not only prevent focus shift, they are also durable and long lasting.
