So......... I'm a bit confused about the number of pics in the data package. I use the large pack. 3000 pics is what I'm supposed to get. I actually only get 2100 in the large package. Now I get a fluctuation if going from high res medium and low.... Correct? So why doesn't the number change when I switch the camera from low to medium to high with the number of pics I'm actually getting on my camera?
