Changing the ISO speed
Lowering the ISO speed results in sharper images, but there may be an 
increased chance of image blurring in certain shooting conditions.
Raising the ISO speed results in a faster shutter speed, reducing 
camera shake and letting the flash reach greater distances to the 
subject. The images, however, will appear coarse.
