EZ Zone System Part 1 - Quick and Easy Film Speed Tests

In today's video I describe the easy way to estimate film speed. Film box speed is set by the manufacturer and is only a rough estimation of how the film will perform. With different developers you'll get different film speeds and this will have a profound affect on your shadow detail and shadow separation. In earlier videos I showed how to get an accurate film speed for your film and developer of choice but here I show the easy way to do the same. It's not as accurate but for those who don't have the time to complete full tests this is what I recommend.
