Using a shot that you took in the photo booth at your best friend's wedding may be taking it a bit too far, but mix that degree of intimacy with good lighting (and a bit less alcohol) and you get how a head shot taken in the late '10's ought to look. Your employees are individuals, allow that to come through.
Whether or not you are bankers, plumbers, or software developers, you want those who view your social media to really see the people behind the product or service. In a world where Instagram, selfies, Bumble, and Snap Chat rule, there is no room for passing up an opportunity to capture your client's attention and stand out from the crowd.
