If I have photos copied over from Photos to my iPad, will they be copied over at a higher resolution/file size on the Air 2 and Pro 9.7 compared to the iPad 2? If so, how much difference? I want to make sure I get a new iPad with sufficient storage. I had a 64GB iPad 2 with probably 40GB of photos on it. I don't want to get a new 128GB Air 1/Pro 9.7 and be shocked that the same photos now take up 100GB of space.
