A new update to Adobe Lightroom introduced in October 2023, Lens Blur (which is currently in ‘Early Access’ status as we go to print) can blur the background or foreground in your image by making a depth map of the image using Adobe’s AI Sensei technology. The tool also lets you add bokeh to out of focus areas in your images.
And while the Lens Blur tool does automate the process considerably, you still have control over the final result. So far, despite being only in Early Access, I’ve been impressed by the results and have found it’s saved me time
