I got some expired True Colors film from my friend. It was cheaply sold for 30 pesos -- a little short of $1 USD. So I tried these films in different cameras and I got exciting results. Although I was expecting that the color shifting won't do much of a hassle, the colors in these expired films came out different. The film was imported from Italy. I don't know how many films of these are still out there but it's a nice way to hunt out!
