A while back someone asked about filter(s) to give a night effect to
pictures shot in daylight. Here is the DFN info from www.tiffen.com:

"Day-for-night (DFN) photography is an effect that makes a scene recorded in
daylight to appear as if it were at twilight.  This is usually accomplished
by the use of a filter that both underexposes by about two stops, and can
also produce a bluish color overcast.  Lighting, contrast, and other factors
contribute to the reality of this effect.

Tiffen offers the Cool DFN filter, which is a lavender-blue color
traditionally associated with dusk or twilight emulation with day-for-night
effects. The Tiffen Monochromatic DFN filter is a bright yellow-green,
almost the color complement (opposite) of the Cool DFN. When you use this,
and perform the necessary color-correction in post processing, you will not
have all of the original colors available, producing a more realistic
monochromatic effect that simulates actual silvery moonlight. Choice of
which one to use is a matter of opinion. Both require an additional
underexposure by ? to 1-1/2 stops above not compensating for them in the
first place. Advance testing is recommended."

I have no financial interest in the Tiffen company.
