I don't think film is too expensive. For about $9 I can get two rolls of 120 FP4, and 4x5 sheets are about $1.25 each. On a good day, I can walk around in the fresh air for 2 hours, and shoot 2 rolls. The same amount of time can yield around 4 sheets. Both come in less than the cost of a 2 hour movie. Even with the (negligible) chemical costs, it's still a bargain. The feeling it gives when nicely processed film is hung to dry far outlasts the feeling even a great movie leaves. And, then, you get to print it...
