Open source Lightroom plugin Focus Point Viewer highlights active focus points
Joshua Musselwhite, an underwater photographer and software developer, has launched a free, open source Adobe Lightroom plugin called Focus Point Viewer. With this plugin, Lightroom users can view the active focus point of their photos, a feature similar to the one offered by now-defunct plugin Show Focus Points.
Musselwhite details his new software on Reddit’s photography subreddit, where he explains that Focus Point Viewer was created as a way to easily see whether the focus points in his underwater images were the ones he had intended to use. The software is currently only mapped for his camera, a Nikon D7200, but because it is made freely available anyone can take the time to map the plugin to their own camera.
Explaining how to perform the mapping, Musselwhite said:
You'll need to map each of the focus points. The best way I knew how to was take 51 photos at each focus point and determine the x,y pixel location for each from the top left using photoshop. I searched and searched for a focus point map for my camera but couldn't find any ... The process is a little time consuming, but it only takes a couple of hours, and is described how in the README file in Github.
The Github README file with the full explanation can be viewed here, and the entire project is available here. Musselwhite has also shared a small gallery showing both the focus points in action and the metadata submenu.
Note that a similar 'Show Focus Points' plugin - with far wider camera support - has existed for some time now; however, we found it quite cludgy to use in practice and would love to see a better implementation, perhaps even natively within ACR/Lightroom.
