12 Days of Tips #8: Matching Exposures in Lightroom

Sometimes you will end up with different exposures from the same scene. This can happen for various reasons. One reason could be that your camera read the scene differently due to very slight changes in lighting or subject position and adjusted settings to get what it thought was a correctly exposed image.  This is common when shooting in Auto or Semi-Auto modes such as Shutter Priority or Aperture Priority.

Shooting in manual mode is a great way to avoid this in the first place, though can still result in different exposures due to unexpected changes in lighting (such as clouds coming or going) and the photographer not adapting in time. Despite this manual is still often a better choice as your images will typically be more consistent if the conditions are the same and you can adapt when they do change.

Regardless of how you end up with similar yet differently exposed photos there is a Lightroom feature to help you get them back on track with a few clicks.

The Match Total Exposure feature will tell Lightroom to set the exposure of one or more photos to the same level as a photo you specify. To use it simply go into Grid view and select all the photos you want to match.  This can be applied to as many photos as you like, it’s not limited to one or two.

Match Total Exposure Example - Selected Photos

Once you have selected all the photos you want to match click on the one you want to use as your baseline.  By that I mean the photo that you want to match all the others to.  Lightroom will use this photo as the reference point when making adjustments to the others. This highlighting on this photo will be slightly brighter than the rest. See the right-hand photo in the example above.

Now just switch to the Develop module and select Photo > Develop Setting > Match Total Exposure from the menus. If you have the film strip visible at the bottom you’ll be able to see Lightroom making the adjustments as it goes.

Voila! The other photo(s) are now match to the selected photo.  It’s not 100% perfect all the time but is a fantastic starting point and sure beats fiddling with multiple sliders just to get the exposure to a similar level.
