There are some Lightroom plugins that make you truly question why the feature isn’t built directly into Lightroom itself, and Show Focus Points is one of those. Just as the name implies, it’s a plugin that lets you see which focus point was used when your camera captured the photograph.
Following the ‘do one thing well’ mentality, Show Focus Points has only that one, namesake capability.
After installing the plugin, you can access it for a particular photograph by going to the Library Menu, selecting Plugin Extras, and then choosing Show Focus Points.
Up pops a new window with your selected image in it that overlays the autofocus points. Using the legend on the right-hand side of the application, you can precisely determine what it was your camera was focusing on when the shutter was pressed.
The interface may be a bit brute in nature, but it gets the job done and gives you some visual information you might have been looking for. As of right now it only works with a select set of cameras, but over time its database will likely grow.
If you’re interested, the plugin available as a free download for both OSX and Windows, so head on over to the Show Focus Points website and give it a try for yourself.
