I will redo my tests using f16 as soon as I have time. It is difficult at the moment, because living in Sweden means "Midnight sun", so I have to wait quite long into the night at this time of year to get a reasonably dark room, where I can control the light. And for a few more weeks the nights are getting lighter and lighter. It is not completly dark before around midnight, and I am too tired today. Maybe tomorrow. :dunno:
