Film testing is one of those things that is just a fact of life if you, like me, choose to continue to pursue that art form. I am no fan of any testing, that is for sure. But, there are times you have to test in order to better understand how things will work.
I never thought I would ever need a sensitometer, but never say never. To compare different film developer formulas, I found that I needed to run some tests. In order to make the test I needed to expose numerous sheets of film and expose them all identically. What I needed was a film sensitometer. What I did was build one. This project was not as difficult as I first expected and most everything I needed was laying around, either in the closet, or the junk box.
I wrote abut my experience designing and building a DIY Sensitometer back in 2009, then shelved the article where is has remained dormant since. Well finally, I drug the thing out and put it up on our web site. Interested in learning more about building a film sensitometer? Head over to the ARTICLES & HOW-TO area of our web site, scroll down the page to the link titled, “BUILDING A FILM SENSITOMETER.” You will see how I did it, and you may just want to try it yourself. . . if this is something you have a need for.
