I live in the Netherlands, and for some time now I'm trying to get hold of a Negative Wet Plate Collodion kit. I have found a supplier (altphotosource.com), but they don't send the liquid chemicals from the US to Europe, that is, they could do it but for shipping costs that is twice the price of the kit.
My question is, does anyone know a European supplier that has a kit like they have? Or one that sells the raw chemicals?
I buy my chemicals (but not for collodion ... yet) at Manuel Riesgo in Madrid, you could try them if you are not afraid of Spanish http://www.manuelriesgo.com/
Try asking at the wet plate collodion photography forum. Just google it, it should take you there.Quinn Jacobson just moved to Germany from the States and he is shooting wet plate there and in France. I'm sure he can help you and he is the founder of that forum. He is always more than willing to help someone. Good luck, it is a great process.
Send me another email (I don't know why I didn't get your first one??). I can take care of you. I get all of my supplies here in Europe and will be in The Netherlands soon (it's close to me).
