Say cheese! This week is all about vintage photography. But we aren't looking at magazine spreads of the 1980's. Glamour shots of the 1950's. We are going all the way back to the 1800's. When carnivals had a tent with a man, a trunk and an odd looking machine that would capture your image for ever. Today we're looking at wet plate photography and how Melbourne based photographer Sophie Caligari is keeping this old technique alive all these centuries later.
