ND8 filter and strobe exposure. Need to check something!
So I'm going to be using an ND8 filter with one strobe on its lowest setting (1.5, Elinchrom), at 1/125th.
I'm getting f4.5 on the light meter. I want to go down to f1.8. So once I put the filter on, I'll put my fstop at 1.8 given that
it's roughly 3 stops down, and I'll keep my shutter at 1/125, but what happens to the strobe - do I bump it UP three stops?
I've confused myself with numbers yet again.
Please help :)
Ps. This is in studio, not outdoors so it's not about blocking out sun or anything. Just the crazy DOF.
