Why does my camera pause after taking pictures at low shutter speeds?
After taking a picture with slow shutter speed (half a second or more), the FZ1 may pause, displaying PLEASE WAIT for a time equal to the shutter speed. During that time, the camera does a dark frame subtraction to combat the effect of hot pixels. In other words, the long exposure time causes some of the CCD sensors to leak charge and appear as bright dots. Immediately taking a second picture with the shutter closed will produce a frame with only the hot pixels, which can be then subtracted from the original frame. This method of noise reduction is what causes the delay.
