Now, just a heads up here. When developing your own film, avoid using old chemicals as you can have bad results. Of course, this appears to apply mostly if you use pre-mixed liquid chemicals. But still, yeah if you mix your own chemicals, make sure to keep the oxygen out of the ingredient containers.
