Guide to Filters

[JeffreyVB]

Can someone point me to a guide to filters? I would just like some basic info on the different types of filters and the effects that they produce. Is there a guide somewhere out there on the 'net? Thanks

Here's one from Heliopan: http://www.heliopan.de/Heliopan-Filters.pdf

B+W has a similar one, as does Hoya. Even Cokin - but I wouldn't suggest those. :D
