Filters and Intellectual Property Rights

I've been wanting to shoot longer exposures for landscapes but haven't had any filters to help with keeping the sky from burning out. I bought myself a Cokin filter set in order to help me do this. I got a ND Grad filter to keep the sky in contrast with the whole image. I haven't yet had the chance to use it but hope to when I get back up to Scotland next week. 

Ian Shipley came into the class to talk to us about intellectual property rights and copyright. The talk was surprisingly very interesting and opened my mind up to the possibilities of not copyrighting your work and what the consequences are. I'm quite disapointed with networking sites like Facebook after reading thier terms and conditions.
