About 3 years ago I shot a short documentary on Kodak 7222. I have not shot anything since, but have been thinking about it lately. I have quite a few roles of stock left in my freezer...they have never been taken out and have never been opned, but they have been in there for a few years. What does everyone think? Should I just suck up the cost and buy some new stock, or would it be reasonably safe to use this stuff up?
