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
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

  • 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

Lightroom deleting images
Lightroom: Deleting Images

  • To delete an image, on the filmstrip, right click the desired image, and select ‘Delete Photo’. When prompted, select ‘Delete from Disk’.

  • To delete all photos on filmstrip, press (Ctrl+a) to select all photos and follow previous instructions. To only select a consecutive group, shift-click the first image and the last image. You can also ctrl-click individual images to make a non-consecutive selection.

Lightroom exporting images
Lightroom: Exporting Images

  • Step 1: Select all the images you wish to use for stacking (generally ctrl-A to select all)

  • Step 2:

    • Library or Develop- right click on any image on the filmstrip, and select export

    • Library or Develop-File>Export

    • Library- In the left panel, select the ‘Export…’ button

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:


(ex. Gewa23811_100mm_1to1.5)

Step 7: Under ‘File Settings’, for ‘Format’ select TIFF. For ‘Bit Depth’ select 8 bits/component

Step 8: Click ‘Export’


  • When finished exporting, delete all of your images from the filmstrip. Be careful not to delete other people’s images, only yours!
