"Exposure"

I found some interesting material while reading the book, "Nature Photography" written by, Tim Fitzharris.
First of all, in order to be a great photographer you have to make sure you know how to use your cameras exposure. Exposure is depicted by the the aperture size and shutter speed of the camera. The exposure can also be controlled manually or automatically. Another way to get the right exposure is to check the histogram on your camera. The histogram will tell you if the lighting in the picture is balanced. You usually would want a bell curve. On the other hand, if you are going out and taking photos of wild buffalo that are constantly moving you have to make sure you get the right exposure on the first photograph. Otherwise, you won't get the perfect photo you were hoping for because, the lighting in the background is moving just as fast as the buffalo. You should do the same thing if you are going to take pictures of landscapes so, you can capture the right photo.
A light meter can be very useful to capture that perfect photo. If you are taking a picture of a scene that has snow or lava than you would use a light meter. Without a light meter the picture would turn out to be neutral gray. However, in order to get the light meter working right you should set the metering pattern on your camera.
In another situation you might be taking a picture of a scene with unusual brightness or darkness which means that you will have to mess around with the meter lighting. However, the meter lighting only measures light not snow covering because that picture would only turn out gray.

For more information on "Exposure" I would highly recommend reading the book, "Nature Photography" written by, Tim Fitzharris.
