amazing-space.stsci.eduExposure-the amount of light allowed to fall on the sensor.Proper exposure-correct combination of film speed, shutter speed, and aperture.The light meter suggests the combinations.Film speed is the first factor The Histogram can help guide you to the proper exposureBracketing is another method to ensure proper exposure.Obtaining Proper ExposureHistogramDefinition: A graph counting how many pixels are at each level between white and blackBlack=left, white=rightUsed to evaluate exposure

Bracketing ExposuresBracketing taking 3 shots at 3 different aperture settings to ensure proper exposure.
