A professional corporate headshot should make you feel great about yourself, it should be a recognizable representation of who you are. Because it's only head and shoulders, an interesting neckline and jewelry add to the finished look. Professional hair and makeup also help with a polished look. If you wear glasses you'll want to make sure they don't create a glare or block the eyes. Grey is also a nice timeless backdrop if you don't know which color to choose. I enjoy being a professional headshot photographer and giving people an image of their face that they are proud to show the world.
