Blur is most frequently caused by movement of the subject or camera. There are several different ways to approach preventing motion blur. Using the L830's built in flash will help, but may not be appropriate for all shooting situations. Try switching to the L830's Best Shot Selector which takes a series of photos and saves the sharpest one. Best Shot Selector can be found in the Continuous section of the Shooting Menu. Vibration Reduction (Photo VR) and Motion Detection can help reduce the effect of camera shake and subject movement. You can find these options in the Setup Menu. If these tips don't help, please contact Nikon Support for further assistance.
