Pei Ketron, travel photographer
Obsessively photograph your dog or cat? This one's for you: Ketron said you should give your pet some space when using Portrait mode. Treats help, too.
"Portrait mode uses the telephoto lens, so a distance of about eight feet away is recommended," she said. "Have treats ready. You'll get the best results when your subject isn't moving."
All said, lighting and distance from the subject appear to be the most important factors to consider when using Portrait mode, but composing a photo with minimal complications in the background will likely give you the best results. Have fun racking up all those Instagram likes.
