I have a Lumix G2 which I really enjoy using. My question relates to how the images get their number in the camera. Here is an example - _1110485, _1110486, _1110487, _1110488, _1110489, _1110502, _1110503, _1110504,_111505, P1110490, P1110491, P1110492, P1110493 and so on. Notice after _1110489 comes _1110502 and …490 comes later. Some images are prefaced with a “P” and then placed out of sequence at the end of the images taken. What causes this and how can I correct it? Is this in the camera or something about the card?
