This is the sharpest and most color accurate filter I have ever used

Would like to share some of the pictures were I have used it.https://500px.com/photo/110732075/sea-games-2015-fireworks-by-senthil-kumar-damodaran?from=user_libraryhttps://500px.com/photo/115263367/ndp-fireworks-rehearsal-by-senthil-kumar-damodaran?from=user_libraryhttps://500px.com/photo/114095901/ndp-fireworks-ii-2015-by-senthil-kumar-damodaran?from=user_library

Simply the best ND filters I have used.

Noticed no color cast like I have with other filters I've used

Quite simply this is the best ND filter I have ever used and would not hesitate to recommend it.
