I'm selling a new sealed Gnomon Workshop: Practical Light and Color DVD. Its still in its plastic seal and costs $49 if you bought it on the Gnomon Workshop site, here is the link if you wanna read up about it:http://www.thegnomonworkshop.com/dvds/jvi01.html
I've got 2 of them which is the reason for me selling one and its a really useful DVD for learning about colour in art and the way lighting reacts to its surrounds.
Price is £22 delivered
My ebay ID is masakonen and my playtrade ID is DVD2GO if you want any proof of my reliablility :)
