The most common mistake travelers make is NOT taking a camera when cruising. “After all,” they say, “a smartphone is all use when I’m home. Why should I also bring a heavier camera?”

Cruises represent new challenges most of us don’t face in everyday life. We don’t spend as much time outdoors; we don’t need to contend with never-ending glare, and our subjects are usually within eight feet of us. Also, we’re not visiting places to which we might never return.

For all those reasons, you should take a “real” camera on your vacation along with your smartphone. The best travel cameras weigh less than 2 pounds—including the lens—and are nearly unnoticeable. They also don’t need a flash to take amazing photos.
