Lab 6: Histograms

Camera Works 2
Histogram Lab (5%)

Due on your blog by the end of class

The purpose of this lab is to understand dynamic range & how to read dynamic range of an image by analyzing the image histogram.

Process:
1.     Photograph a white object in three different scenes:
·      A high-key scene (white on white)
·      A low-key scene (all dark scene other than our white object)
·      A scene with a variety of tones
2.     Open the three images in either Photoshop or Lightroom
3.     Take a screen shot of each of the three images’ histograms
4.     Post all three images, along with their histograms. Be sure to identify each item on your post.
5.     Answer these questions on your blog:
a.     According to the histogram, where do most of the pixels in your high key image fall (left or right on the histogram)
b.     Are there any pixels in the high key image that would not print with detail?
c.     According to the histogram, where do most of the pixels in your low-key image fall (left or right on the histogram)
d.     Are there any pixels in the high key image that would not print with detail?
e.     According to the histogram, where do most of the pixels in your varied tones image fall (left or right on the histogram)
f.      Are there any pixels in the varied tones image that would not print with detail?
g.     Considering the information on the histogram, do you feel your camera is properly exposing the high key and low-key scenes? Explain your answer

h.     Which histogram shows the most dynamic range?
