What's the difference?

A branding session is more in depth, similar to a portrait session, lasting up to a few hours and is meant to visualize the personality of your brand. The objective of your brand photos is to visualize the mood, look, and feel of your brand (this can be literal or not). Like I said, Branding sessions are much longer and range from a variety of poses including closeups, three quarters, and full body. Subjects can look away from the camera, engage with props, etc. Branding photos are great for web banners and pages, social media banners and posts, as well as printed materials.
 

Headshot  or Branding

Headshots are simply what the name implies. Headshots typically are closeups intended for the viewer to see your face. These are almost always taken with the subject facing forward and very formal in posing. A headshot session is typically shorter in time than a branding session, lasting no more than 30 minutes to an hour. Headshots are great for social media profile pictures, web pages, and business cards.
