This is not an easy question to answer because it will depend entirely on the image file size your camera records and how many pictures you intend to shoot. We will be seeing plenty of amazing things, so we recommend at least four 16GB cards for a 10 mega-pixel camera and at least four 32GB cards for a 24 mega-pixel camera. Erring on the side of more rather than less is the safest bet. Regardless of the capacity of your cards, it’s always a good idea to bring at least two in case one fails. We recommend bringing more, smaller-sized cards rather than fewer, larger-sized cards to reduce the risk of loss or damage.
