Photo Vlog 11: How long does color chemistry last?

Have you ever wondered how long C-41 color chemistry can actually last? Did you think the manufacturer’s recommendations were a little too conservative? When its hard to buy the stuff in small quantities, this becomes an even larger problem. What if I told you that it is actually possible to perform experiments, collect data, and prove that your chemistry is still good before running any real film through it? Come with me, as I deep dive into the world of “process control“ and actually attempt to tackle this problem with the same sorts of measurements and data analysis that a professional lab might use.
