Using the Histogram
While looking at the image and using your own judgment is important using the Histogram can help optimize the image quality.
A histogram evaluates the tonality of an imageIf the histogram is skewed towards the left, the
image is (likely) underexposed/too dark. If the histogram is skewed towards the right, the
image is (likely) overexposed/too light. A centered histogram is usually good, but note that a
specimen on a white background will likely skew the histogram to the right, black background skews left, etc.

Develop: Using the Histogram
For optimal lighting, the tonality should fall between the two lines indicated by yellow in the Histogram
Operating LightroomThe Develop module is used to determine the
proper lighting for a set of photos
This picture is overexposed – too much image data displays as pure white.
In Develop: when a picture is overexposed, in the Histogram, click the top right arrow. The over-exposed parts will show up as red.

Operating LightroomBy clicking the top left arrow in the
Histogram, any areas that are underexposed will show up as blue.
Underexposed – there is literally no image data here, so it gets displayed as pure black.
Under-exposure indicator
Operating Lightroom
*Notice that as the image appears lighter in the second image, the exposure indicator in the histogram moves further to the right.
Operating LightroomAfter image slices have been taken, the entire
set will appear in the filmstrip.Note: When viewing pictures, either the Library or Develop modules can be used
