It's like the electronic MPG info on new cars. It tells you how far you can drive on the gas in your car, but that changes every mile. It's just an estimate. The camera stores data on the memory card. Every picture can use a different amount of data, so the camera estimates.
Right. Complexity of the picture affects how much of the card is used. Picture of a blue sky uses less, while one of a busy street uses more.
