Filters and the Mothrs of Invention

Well Frank Zappa has not joined the ranks of happy snappers but in an effort to modify equipment i guess imagination is the only limiting factor.
Ihave been trying to rig some filters for my Agfa Clack but as there is nothing really readily available one has to modify and invent as one goes along.
But i guess that is the fun thing about Photografy : it's dynamic nature as people explore differen techniques and approaches to achieve a goal.
It's no different to what happened in the early Days only the technology has improved.So in a sense exploration and building on the ideas of other is a valid and good thing,it can only lead to improve ones own style
