b/w film in blue light

[Peter_S]

Hi!
So...I am probably photographing a band on the weekend - in a relatively dark cellar, lighted only with blue light. I am not really sure if that matters much...or?
I normally use Ilford Delta 3200 and HP5+ pushed to 1600 iso. Anything to consider, any recommandations?

If you think of the way blue light is recorded by black and white film that'll give you an idea of what to expect. A blue sky will normally come out a lighter tone in a print than you might expect because the film is very sensitive to those wavelengths. Shooting under blue light in a cellar shouldn't cause too many problems but you might want to bracket a stop or two under in case the negative comes out too dense. That's how logic tells me it should work but maybe there's a spectral sensitivity expert in the house?
