Minimizing a Double Chin in Photoshop Elements or Lightroom

Study the chin area in the photo of me above (so sorry to force it on you – it was a setting-the-exposure click). Rather than focusing on the overall appearance, think about how the actual pixels are different from each other from the face to the chin to the neck. Ideally, we want the chin to be brighter than the area under it – it should cast a shadow on the neck. However, if your chin is, ummm, generous like mine, you have more unshadowed area than you’d like. You’ve probably already guessed the solution to this by now, right? Paint a shadow into your image!
