The credit card format does not exactly find the pictures of childhood, but notes that at least the advantage of being much more easily transportable so we can more easily protect as these pictures are unique unlike a digital camera. Paper quality or chemistry seems better than the pictures of our childhood unless my memory have kept the image pictures after a while poor sun exposure. However we must not forget that this paper and chemistry to snapshots AND THAT CONSEQUENTLY quality is less than a digital camera. This is what makes their charm.
