Lightfinder is a free Chrome add-on developed by Nemesys that provides a convenient way for Lightroom users to view the editing settings used on a photo. By simply pressing "alt + A + click" on any photo, Lightfinder displays the development information on the right side of the screen, in a scrollable bar that Lightroom users will find familiar.

As a beta version, Lightfinder is still in development and may have some limitations or bugs that need to be addressed. However, it offers a useful feature for photographers who want to learn from and analyze the editing techniques used on a particular photo. With Lightfinder, users can gain insights into the editing settings applied to images in Lightroom, allowing them to improve their own editing skills and learn from others' techniques.

Please note that Lightfinder is an add-on specifically designed for Lightroom users and may not be suitable for those who do not use the Lightroom software. It is available for free on the Chrome platform, providing an accessible tool for photographers seeking to enhance their photo editing knowledge.
