Hi all;
Is there a web site anywhere that lists or shows spectral transmissions for photographic filters?
Give you an example of the sort of thing I am looking for, wee this web site
http://www.astrosurf.com/~buil/filters/curves.htm
Reason I am asking is not all red or yellow or magenta filters are the same. Tried the various company web sites (Hoya, Tiffen, B+W, etc) but failed to find anything. Maybe I just didn't look right.
thanks much
joe
