I have been searching a little and have not found much info relating to filter factors for the yellow-green or green filters.
I was commenting elsewhere that I haven't used these enough, so I'm going to get one or two filters soon, so I'm wondering if we could gather a few numbers from people on this subject.
It seems that even with the mainstream films from Kodak and Ilford, the green sensitivity is one of the more variable quantities you could pick.
Also, there are a few types of yellow-green and green out there - brands could be mentioned.
I note that these days you don't get any info from the film manufacturers.
I haven't bought a new filter for years ;o) so I don't know how much info they provide.
If possible ( Ha ! ) I'd like to avoid digressions into meter variables and what the scene contains.
Let's say we're just looking at a grey card or a mixed scene.
What can people offer me ? ( Filter type + film )
Thanks in advance ...
