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
Over-exposure indicator
Histogram
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 overexposed parts will show up
as red.
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.
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

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
 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

Lightroom Catalogs>
Imaging_Class_Spring12> Your folder>
Specific specimen folder’
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. Gewa23811_100mm_1to1.5)
Step 7: Under ‘File Settings’, for
‘Format’ select TIFF. For ‘Bit Depth’
select 8 bits/component
Step 8: Click ‘Export’
