A new style Headshot / by Ed Shanahan

On Monday I had the pleasure to take a headshot for a recently retired dentist who is joining a dental consulting practice.  What made this a little different is that the headshot needed to look similar to ones already on the consulting company's website.  For me that meant first studying the photos already on the site to deconstruct how they were likely made so I could reverse engineer the process.  An interesting challenge.  To create a similar (but better!) look, I used a black backdrop, a horizontal crop and a modified lighting arrangement.  What do you think?  Which image do you like better?  He needs to choose and is torn between these two.
