I have some tiffen screw on 77mm ND filters, which have a greenish tint depending on how much filtration i put on it (stack). This really annoys me and as such i'm gonna be getting a heliopan soon for more run and gun situations. However I'm also thinking of getting a mattebox for some situations ( where i have a crew) and would like some 4x4 ND filters that do not affect the image when stacked in the mattebox. Any good ones out there that dont affect the image that you guys can recommend?
