The basic editing in Lightroom Classic allows you to make global adjustments and affect the color and tone of an entire photo.
For many photos, making corrections to the specific subject of the photo will make the image stand out and look better. For example, faces or entire bodies.
Imagen’s Local Adjustment tool will automatically find the photo's main subject in a similar way that Lightroom selects a subject, applies a mask using brushes, and then applies a local AI edit to that mask.
Using this feature only requires checking a box.
It will significantly enhance your edit, as the photo subject will receive additional editing separate from the rest of the scene.
