Metering Modes, Exposure
I just learned about the metering options using my point-and-shoot camera. My camera has three options: evaluative, center weighted average, and spot.
Evaluative basically means the camera divides the whole frame into several metered zones. It averages all metered zones to decide on how to expose the shot (exposure).
Center Weighted average means the camera will take information from several metering points around the frame but will give more weight to those in the center.
Finally Spot mode tells the camera to do it’s metering from a very small ’spot’ in the scene, ignoring all others. This is a very useful mode for tricky lighting conditions where the whole scene is either darker or lighter than the point that you want to be exposed correctly.
Today, I also learned about a correctly exposed image. This means that the right amount of light has exposed the image sensor. It depends on the aperture of the lens and on the shutter speed which decides how long to leave the shutter open receiving light. The ISO option can also be used, but need to reseach more on that.
