Should it be Head Shots or Headshots? I see both. Autocorrect wants to make it two words, and I tend to like that. Moreover, I prefer the term, “business portraits.” But that can be more than just a headshot, which normally is no more than the head and shoulders.
Regardless, a head shot should say something about you, and as a photographer who has made quite a few of them, I can help you decide on the look you want or need for your business.
