A lot of the best digital cameras out there have a built-in GPS system that helps you navigate your camera in the wild.

That GPS system is also known as a “lumens sensor” or “luminance sensor,” and it has the capability to determine your exact location and even give you a hint about where your camera is.

The sensor can even tell you what your camera’s exposure was, if you’re using the same lens as your subject.

There are many reasons why you want to avoid this sensor, but the good news is that you can use it.
