Blue channel B&W boy
I like 'em. They have a pre-panchromatic look from the days when b/w film was more sensitive to blue light than to green (as still less so to red). Panchromatic film (so termed) has been around a long time, but heightened blue sensitivity persisted.
I use blue filtration often in post to darken foliage. It's funny, because I never even owned a blue filter when I was shooting film.
