Any views or experiences will help.
I recently purchased a Tiffen 3.0 to help with getting long exposures. This produced a thick pink line across the whole image. I'm less than impressed, thankfully a refund has been granted.
After doing some research for an alternative I have seen 10 stop filters made by NISI and Haida. Does anyone have any experience with these or can you recommend another make?
Thanks in advance and keep up the good work.
