Ideally we'd notice distractions while shooting and move them out of the frame, but sometimes things happen quickly or we just don't notice how distracting an object is until we are editing the image. Instead of tossing away an image or delivering an image that doesn't meet my standards, I always try first to remove the distraction. Sometimes that means that I will send it out to a third party to have them remove it, but if it's a fairly simple removal with a plain background then I'll do it myself using both Lightroom and Photoshop.
In the video below I'll walk you through how to start in Lightroom using the clone/heal tool and then pulling it into Photoshop to use Fill -Content Aware, Patch, and a brush.
