Metering

Now that you're armed with the basics of aperture, shutter speed and ISO, have you ever stopped to wonder how your camera is determining how each of those settings should be adjusted when you press the shutter button?  If you're in aperture priority for example, who is determining the shutter speed?  Why the camera of course.  Using a built in light meter, your camera is measuring the amount of available light to determine how best to adjust for the scene in front of you.  Rather than reinvent the wheel, this week I'm directing you to another great Digital Photography School post to help you gain a better understanding of the various metering modes.  Take a look at "Metering Modes Explained" and then invest some time to experiment with metering modes on your own camera.
Next week we'll discuss two tools that take the guesswork out of understanding whether or not your images are properly exposed.
Until next time, keep click'n.
