f-number

bobbyqualls

Hello,
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.
Thanks

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.
