Like film in a camera responds to the light it sees, not for the correction
that our viewing of the scene makes, the UV filter only corrects for this
part of the spectrum it records making the resulting data closer to the way
we perceive the paper when viewed under these very conditions. Sorry if I
can't explain it more clearly, when I taught photography I explained with
film examples which are better than words.
