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

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

Operating Lightroom The 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. Histogram Over-exposure indicator

Operating Lightroom By 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 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

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 Second to last photo Last photo In-focus Not in-focus
