Argyrotype workshop

Looking through the workshops on offer at DCA in Dundee I noticed one that intrigued me. A one day course titled Argyrotype. This procedure is based from photos or negatives as this is what you are asked to bring along. The reason it caught my eye was that the images reminded me of one of my favourite picture books titled The Arrival by Shaun Tan. Trying out this technique may lead me in an unexpected direction with my art or project but I won't know until I try.
