Then I must confess I have no idea what you are talking about when you
say you want to "lower the density without changing the colour" because
it is "too dark" when "properly dense".

If extinction doesn't have any noticeable effect, it means that the "too
dark" effect you observe is not due to a lack of light from the
background getting through to the camera.

I must consequently assume that the "too dark" effect you observe is
instead due to a lack of light /scattered to/ the camera, but to get
more of this light you need a /higher/ density rather than a lower one.
