My fiance bought me a D3100 a few months ago. I take pretty good day time photos, but I would like to take some night photos. I am still trying to learn how to adjust the f-number. I know when I turn the dial to the upper right of the screen I am able to change the apperature. I would like to play with the f-number to see what the quality will do. Any help would be grateful.

    Yes, to change the aperture, hold down the +/- button on top of the camera, and turn the Command dial (the one you mentioned).
    It's on page 77 of the main manual.
  • I was wondering the same thing. Thank you!
  • Hi, can someone tell me how many clicks of the dail is one f-stop, please?
