Ilford made an inexpensive set of color printing filters for
Ciba(Ilfo)chrome printing which are convenient for cutting up
and taping to flashes - I use them for various corrections
(or reverse-corrections when using correction filters on the
lens with daylight-balance transparency film) on my SB-24's.
The recent Nikon flashes have a nice warm-daylight correction
already - if flash is the primary light source, a skylight
filter on the lens may be more convenient for adding warmth.
Hope This Helps
