I'll appologise to all the 'non-thick' people, as i'm probably being really thick. I'm fairly new to digital photography, am and just starting to experiment with filters.....
However i've found it quite hard to figure out which filters do what..... I'm sure i can't be the only newbie who's had trouble with this. I'm not entirely thick, as many are self explanitary, or quite commonly used, like polarising filters etc....
But i was wondering if anybody knows of any resources that say (or have examples of) what some of the more obsecure filters do?

Thanks in advance, and sorry if people think i'm asking a very obvious question!!
