How do you change the f-stop on a Nikon D-40x?

Question

my friend screwed up my camera and usually by changing the iso and lighting and adjusting the shutter speed makes it change but its not (manual setting) . its stuck at F22 and the picture of the shutter speed on the camera screen doesnt move. or is my camera just broken.

Answer 1

You can try to reset it back to factory default setting, it should resolve you problem.

Go through the setting manual, there should be a reset function.

Answer 2

If your friend screwed around with your camera the first thing you should do is perform a "green dot reset"  Hold down the info and the magnifying glass buttons (the two buttons with green dots next to them) until the display on the top turns on and off.  This will return most of the shooting settings to the default mode, and erases any odd settings your friend may have entered.

As far as changing the f/stop goes, Turn the selector dial (top right) to "A" as in "Aperture".  The command wheel, that is, the one you move with your thumb on the back of the camera, will change f/stops.  If the dial is set to "S" as in "shutter" the command dial changes shutter speeds.  For general photography, I suggest leaving the selector dial in P or Auto.  

Finally....don't give your camera to people who don't know what theyre doing!  DSLRs are complicated pieces of equipment!  Good luck and happy shooting.

On full manual setting it won't change depending on the other settings (that's the idea behind manual). You'll have to change it yourself. I believe that with the D40x's you need to hold down a certain button and then turn the wheel to change aperture.

EDIT: To change aperture you need to hold down the +/- button (under the on switch) while turning the wheel.
