Reading the post I´m thinking about that I use the 18% grey card with false color. In my opinion is very useful. Is a good reference for me. What do you think about this?

thanks

Hi,

I understand the useful of contrast viewing filters, but not the rest of them.

At the Tiffen web and American Cinematographer Manual the information is very limited.

Anyone has any more information about this tools?

Thanks
