So here’s the initial photo/video count from Japan (before I go through them and ditch the ugly/blurry/repetitive ones):
Camera photos – 2,921 (DisneySea – 518, Disneyland – 769, Tokyo Sea Life Park – 610)
iPhone photos – approx. 150 (approximate because some are repeated pics, after editing in different apps)
Video clips – 96 (mostly Disney parade/show bits, and a good number of fish videos from the Tokyo Sea Life Park)
All that ate up 7.12GB on my iPhone, a full 8GB SD card, and about 7.67GB on a second SD card. Whew.
