    My R72 arrived this morning, and I've been practising.
    However I'm getting some things I didn't expect.

    I've set up the camera according to Bjørn Rørsletts site, with high ISO, increased EV and long exposure


    ISO1600, f2.8, 2mins EV+3, on D80 with 24mm f2.8

    Right the problems.

    What is the cloudy over exposure in three places at the topmost picture? (Corners and centre-left) It happens as well at 30secs when the banana is barely visible, but the clouding is!?

    Is that usual high ISO noise (NR was off) or is that an malfunction?

    Sorry if these are newbie questions, but thats what I am!:biggrin: and proud!!
