85b filter on B&W film

I got one of these salmon CC filters in an oddball size paired in a sale with an ND filter I needed. Just curious if anyone has used one on B&W film. I'm suspecting a subtle effect sorta like a very light yellow contrast filter would do but I really have no clue. I guess I need to just try it, all I saw online was people's theory on what it would or wouldn't do, not from anyone who had actually tried it.

Hi,

good question! As a bycatch a KR12 found it way here.
These are blue reducing filters, blue is not cut of like using an orange filter.
So in theory it should give brighter shadows when photographing sunny scenes.
And it works! The look is similar to a dark yellow filter, but indeed in a subtle way smoother.
Maybe a fine filter for portraits? I like the filter with dark brown eyes, like here:



Just give it a try!

That's always been the catch 22 with these blue cut filters. It hurts the shadow detail so to try to retain that, I end up dialing in more exposure. I might give it a try this next week on some rolls compared to a yellow and regular orange and see what it looks like.

Hi again,

the 22 even darkens the greens what I don't like...
Long ago I used it a lot, today only seldomly.
More exposure helps for shadow details, sure - but the balance of color stays off.
Some just like that as an effect, that's ok, too.
Some test shots are a good idea!
