Match Total Exposures Function
The Match Total Exposures function will match the overall exposure of a group of images, so they all look consistent. There are several scenarios for which this is very useful. However, there’s one crucial thing to note about the match total exposure feature.
It uses your original camera settings to determine the exposure settings. If you have shot all the images in manual mode with the same settings, but the scene and then the exposure changed, this feature won’t work.
In the develop panel, choose the first image you want the other images’ exposures to match.
Get the exposure of that first image to how you want it.
Now shift-click to select all the photos you want to have the same exposure settings.
Go to the settings menu.
Select ‘match total exposure’ (alt-shift-command-M for the shortcut).
Location-based Presets for Lightroom
Using location-based presets can be very handy if you often shoot in the same location or repeatedly do a series of shoots.
Also, you can use a radial filter over the entire image and then input the desired exposure in the radial filter sliders. To change the intensity, press alt-click and drag either left or right on the image to simultaneously reduce/increase the opacity of the settings of every slider.
