i might try my best to get over my aversion to filters .. dark blue ?
and with the others, should it be the dark filters or the light ones ?
I guess a "primary blue" filter (Wratten #47B) should give basically the effect of a blue-sensitive-only film. To get faux-orthochromatic, you'd need more of a "minus red", which apparently is Wratten #44A.
