Like the Photovision Roadshow thread by David, this is mostly geared up for the digital users but there are some interesting exhibitors selling darkroom & studio equipment and a web design company. Noble Fin Art looks interesting.
Sorry I may have jumped the gun as Barker Photographic does sell darkroom equipment but I rang Paddy this morning and he said he wasn't going to show any darkroom stuff but would bring some if I or anyone else wanted.
He sells Meopta Enlargers as well as Patterson and Nova darkroom products.
He does sell Print Washers Fintan and would bring one up for you to look at if you wish.
