Focus on photography editing software
If you are a professional photographer, then you probably spend all your time making decisions. What to focus on to get the best shot, how to get that shot, whether you've got the best lighting set up.
When you're shooting portraits for a living, then you nearly always want to get the person in focus first, most importantly their face. The background focus, especially in a studio setting with a plain
background, is usually less important than the subject.
