Advertised in this week's Amateur Photographer, Fujifilm are running a competition for images taken on Velvia 50, Velvia 100 and Velvia 100F.
Details here: http://www.velvia50.co.uk
"The lucky winner will enjoy a pre-tour tutorial with the landscape photographer, Charlie Waite, before leaving for seven nights in Turkey, including five nights in Istanbul and two nights in Cappadocia".
I'm not sure if the original Velvia is included as it does state Velvia 50 (which is the title of the re-introduced film). I have e-mailed fujifilm with this query and I will post their reply when I get it.
