Hi,
I've had a Tiffen IRND 1.5 filter recently returned and the filter appears to have a darker center then the outside, almost as if where the 4x5.6 filter tray sits is one tone and the exposed filter inside of the tray is a darker shade.
Has anybody seen or heard about this before?
When placed in front of a camera, it's unseen, however very obvious to the human eye.
Thanks.
