4. Using The Camera Histogram  What Does a Histogram Tell Us?  The histogram can tell us if our exposure is correct and if the contrast is acceptable.  Remember, the upright bars show the range of tones that can be captured by the sensor. Instructor: David King dking@sdccd.edu

5. Using The Camera Histogram  What Does a Histogram Tell Us?  This histogram is indicating an under- exposure where there are more dark tones in the scene than were captured Instructor: David King dking@sdccd.edu

6. Using The Camera Histogram  What Does a Histogram Tell Us?  This histogram is indicating an over- exposure where there are more light tones in the scene than were captured Instructor: David King dking@sdccd.edu

7. Using The Camera Histogram  What Does a Histogram Tell Us?  This histogram is indicating a perfect exposure where all of the tones in the scene were captured Instructor: David King dking@sdccd.edu
