For each law firm that we work with the specifications for their attorney headshots changes.  While in general we have found that many people prefer a more personable look, it isn’t for everyone.  We try to photograph a variety of expressions for each person who comes in for a headshots session and at the end we review their images.  A subject that always comes up, either during the shoot or during review, is what type of clients are you working with?  The type of expression a defense attorney or litigator may use might be very different than someone handling a private estate or general corporate work.  In the end it comes down to personal preference, you have to look like someone who is both confident and can get the work done and as an attorney you and your expertise are the asset you are selling to your clients.
