Filters

Thanks to Ma®tini for this link to a test of all kinds of UV filters.  I've paid £14 for a set of the five main colour filters for black and white photography, and was wondering about the enormous price differences between them and well known brand names.  So this is a note-to-self to look at the results of those tests, when I've time.  And I'll assume that whoever makes the best UVs makes the rest of their filters as good.
