Right again. I judged by my intimate knowledge of my process and its
accustomed results, which told me that my prints were coming out
surprisingly crappy: flat and lifeless. Since the dichromate had
darkened and I knew it was older than I'd ever used it, my first
thought was to throw it out and try fresh solution. I did that and the
prints immediately began looking as they should and have continued to do
so, being that dichromate has never sat around that long in my shop
again. No sensitometry required to conclude that the printing properties
of the aged dichromate solution had changed from what I'd long learned
to expect from it.
