I love toy cameras and own a Diana and a Holga,
i also have a 110 toy keyring camera that works and
a range of old kodak box brownies. I have discovered that the toy cameras are really becoming very popular with new photography students and think it is a great thing for the filom industry as it is really boosting sales of medium format films.
I own and operate a Pro Lab in Sydney where there isnt a day that goes by without someone form the public walking in with rolls form a toy camera and asking can u please process and proof this and dropping comments like "digital cant do this" which is music to my ears. I try and support Toy camera photography by having a bin in my lab which i sell all sorts of medium format film for $3.oo a roll. that way its cheaper and more accessible to play with.
I love to play toys are great!
