Today's Must Have is tight crops and chopped heads. I love the look of it, and I will almost always include a few tight crops. There are still a few "rules" (guidelines) to this, like don't cut off the chin or ears. And don't forget about the rule of thirds. These are a great way too see details in the face, the colors of the eyes, freckles, eye lashes, and so many other precious things.
So if part of the head is chopped off, its intentional. Here a few of my favorites.
