Histogram Part 1: In the Camera Instructor: David King

Using The Camera Histogram  What is a Histogram?  A Camera’s Histogram is a type of horizontal bar chart that plots the distribution of tones in the scene. Instructor: David King The “Y” Axis shows relative frequency of occurence. The “X” Axis shows the tones the chip is capable of recording The range of the bars indicates the range of tones that are in the captured scene

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. Instructor: David King

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

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

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

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

Using The Camera Histogram  What Does a Histogram Tell Us?  What other histograms indicate… Instructor: David King
