Adjust the camera nikon d5100?

Not sure what you're trying to ask here. Do you want to know how to manually adjust your aperture, iso, and shutter speed? If so, put the camera in M mode and read your manual. It will tell you how to balance those 3 things to correctly expose a picture.

Your best bet is to read the CD manual that came with the camera. It's much more complete than the hardcopy. If you don't have the CD, you can download it from the Nikon website.
