hi
there is a lot to takin good pictures but its easy too
now when are you facing this prob during low light situations or regularly
if it is during low light then pitching up ur ISO settings say from some 80 or 100 to atleast 400 or 800 should do the trick but beware of a lil picture noise,
also u can turn on the continuous focus(CF) setting
also when you are taking a picture try to focus on the subject by pressing and holding the shutter button only halfway then once you r safisfied with the way it looks press it down all the way to take the picture this works for all photos whether in day light or during low light
if u have any further questions u can contact me on
[email protected]
cheers
pls rate if this was any help
