lightroom usage for bio 498 698
Lightroom usage for Bio 498/698
  • The 2 main modules used will be Library and Develop
  • Library: Import and organize files
  • Develop: Review and evaluate the overall tonality of your image
lightroom importing files
Lightroom-Importing files
  • Importing from a card
  • For class purposes: pictures will automatically show up in Lightroom when taken using the Camlift
using the histogram
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 image
  • If 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

  • The Develop module is used to determine the proper lighting for a set of photos

Over-exposure indicator


In Develop: when a picture is overexposed, in the Histogram, click the top right arrow. The over-exposed parts will show up as red.

This picture is overexposed – too much image data displays as pure white.

  • By clicking the top left arrow in the Histogram, any areas that are underexposed will show up as blue.

Under-exposure indicator

Underexposed – there is literally no image data here, so it gets displayed as pure black.

*Notice that as the image appears lighter in the second image, the exposure indicator in the histogram moves further to the right.

  • After 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
