Hi all, i got a pentax kr with single kit. Sorry for the newbie question that i am going to ask. I always do shooting on kids indoor and outdoor. When i use aperture priority, the image that came out will be blur basically i can't see the kids. I am using ISO 1600 or 3200, aperture at 4.0. Can someone enlighten me what settings should i put to get those clear image with nice bokeh. The reason i wanted to use ap priority so that i can get clear image with some bokeh at the backgroud.
