My cheapest camera is the Kenlock Kg1 that I got for 8 Euro in a vintage market in Palermo. I only work around film cameras (35mm, 120mm, 110mm, instant). I've always been charmed by old pictures from the past that I decided to recreate that same atmosphere in my work.
I started to shoot and experiment with different type of films (I love expired film) for years now. Removing dust on the scans and to digitally print my images are the only post-processing I do.
The imperfection and the film grain became my hallmark, often influenced by my musical tastes (New Wave, Post Punk, Alternative rock).
The camera you're using isn't really as important because what matters is your point of view. Almost everyone of us has it. Some are just more gifted with it more than others.
