  11. Lightroom-Importing files • Importing from a card • For class purposes: pictures will automatically show up in Lightroom when taken using the Camlift

  12. 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. http://www.adobe.com/designcenter-archive/lightroom/articles/lir1at_histogram_print.html

  13. Develop: Using the Histogram For optimal lighting, the tonality should fall between the two lines indicated by yellow in the Histogram

  14. Operating Lightroom • The Develop module is used to determine the proper lighting for a set of photos Over-exposure indicator Histogram 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.

  15. Operating Lightroom • 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.

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

  17. Operating Lightroom • 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 Image slices on filmstrip

  18. Operating Lightroom • Sometimes the last photo will have been overshot. This makes the lowest in-focus point be in better focus in the second to last photo. Simply delete the last photo from Lightroom In-focus Not in-focus Second to last photo Last photo

  23. Lightroom: Exporting Images Step 5: Under ‘Export Location’, if needed, select ‘put in subfolder’ and name that folder Step 6: Under ‘File Naming’, for ‘Custom Text’, the name should include: CatalogNumber_Lens_Magnification (ex.
