It's true C-41 needs to be color-corrected in post anyways so i just shoot it as is to get as much light as possible. With B&W and E-6 you don't have a choice, and E-6 is really picky too. Cheap cokin filters always had color casts for me.

Yet everyone shoots B&W with filters. It's the equivalent of channel mixing for digital folks.
Originally posted by elho_cid Well sometimes I use them with digital as well. There is a nice downloadable pdf guide to these filters on B+W site.
They eat up some light but with tripod it doesn't matter. Result is usually far better (even on digital, the DR, contrast and details improve with filter corrected WB)
I don't understand why they would improve contrast, detail, or dynamic range. Sounds like marketting BS from filter manufacturers.
