If this is your first headshot, or its been a while since you stood in front of the camera, don't worry - we got you!
First, let's make sure we're on the same page of what a "Headshot" looks like. To me (along with Myself and I), a headshot encompasses an individual's shoulders and head. Basically, chest and up. Anything below the chest I consider a "Portrait", or as I call it in the studio, an Editorial Headshot (basically, more of you is in the photograph).
If you're not sure where to start in terms of aesthetic for your new headshot, I recommend sticking to what looks clean, modern and what works. I recommend we start with an off-white / light gray background. This works well on so many levels; no distractions in the back, the focus is on you in the photograph (which is the entire point of a headshot), and we can concentrate on expression and the vibe you want to convey.
Embrace the negative space - it allows for copy on a website, or more cropping options in the future. The off-white background, also allows for easy cropping for your web designer to change up the colour, or use it in various ways in your advertising.
