One of the nicest benefits of using a digital camera is having virtually unlimited film, so you can afford to take pictures of anything that tickles your fancy. For example, when I meet up with travelers I often borrow their guidebook for a moment just to take pictures of the pages that list hostels and guest houses, or to get maps of the area. Or, when I see a sign that I'd like to remember, or even a page in a book that I'd like to record, my secret spy camera comes in very handy.
