If he's intending on only using image-forming light in, then a hard-mat(as Vinny mentioned) will allow for more contrast(due to less 'scattered light' bouncing around within the camera housing.
Tim,
IIRC from when I was researching a similar task myself, make sure to have your lens set/focused for ∞ when cutting/sizing your hard-mat, not closer than ∞. Even if you're using a helicoid for focusing, the extra amount of scattered light(due to lens being farther from film, so IC gets bigger) will be negligible, at best. Hope you're well! Been a while!
cheers,
Dan
