filters - colour absorption question
pardon me, but I'm not sure where's the best place to ask this, so I thought I'd start here.
I normally print black and white, and I have multigrade filters for that, folks who have experience in colour printing will no doubt understand the filters better than me, so here I am.
If I was wanting to absorb more of the green and some of the red spectra from a light source what colour filter would I use? I know that a blue appearing filter will remove more of the red and green, but what colour will a filter which removes some of the green as well appear?
