I am not certain if this is the right section of the forums for this question - please let me know if it is not (and my apologies if that is the case). Here goes: I mainly shoot B&W, and am somewhat proficient with basic filter knowledge (which colour does what, applications, metering issues, etc.) However, I have read this article http://www.acecam.com/magazine/filters-faq.html , by a gentleman who really seems to know what he is talking about (not to mention has been taking photos since before I was a twinkle in anyone's eye). His name is Lars Bergquist, and he suggests that green filters are a total waste of space in a B&W photographers camera bag! The reason I ask, I have purchased a large lot of filters, many of them of types I need, some that I could use, and some that are throw aways - all for a price that more than justified it for the ones I wanted alone! Which category do the assortment of greens fit into? Now, before I spend money and time on film to test this theory ( I was thinking a still nature shot including objeects of all the majour colours, some cut flowers and leafs and person behind them ), I thought I'd ask - can anyone conclusively prove or disprove the usefulness of green filters in B&W photography? Thanks for the input in advance, Peter.
