Deciding whether to smile in a corporate headshot depends on several factors, including the image you want to convey and the norms of your industry. A smile can communicate warmth, approachability, and positivity, which are beneficial traits in many business contexts. Smiling, particularly a genuine Duchenne smile that involves both the mouth and eyes, can make you appear more likable, trustworthy, and competent. This type of smile is generally more appealing and can create a favorable first impression in the professional world.

However, in some industries, such as law or finance, where seriousness and professionalism are paramount, a neutral or serious expression might be more appropriate. These expressions can convey authority, expertise, and gravitas, essential in establishing credibility and trust.
