When people book professional headshots, business headshots, LinkedIn headshots, corporate headshots, or personal branding portraits, one of the first questions they ask is simple: should I smile? The better answer is more thoughtful: yes, in most cases, but the right smile depends on your industry, your audience, and the kind of confidence you want your headshot to communicate. After all, a headshot is not just a nice photo. It is often the first professional impression someone sees before they read your bio, visit your website, or decide whether to contact you.
Why Your Expression Matters More Than You Think
A headshot works in seconds. In fact, Princeton researchers found that people can form trait impressions from a face after only 100 milliseconds, including judgments about likability, trustworthiness, competence, and aggressiveness. (Princeton University)
That does not mean every first impression is fair or accurate. However, it does mean your expression matters. Therefore, the question is not whether smiling is “good” or “bad.” Instead, the real question is what kind of smile supports your professional goals.
LinkedIn’s own profile-photo guidance notes that a profile photo is a key part of your professional presence and that simply having one can make your profile far more likely to be viewed. It also recommends a recent, clear, high-resolution image with your face taking up enough of the frame to be recognizable. (LinkedIn)
For this reason, a professional headshot photographer does more than press a button. A skilled photographer studies posture, lighting, facial tension, eye connection, jawline, wardrobe, and expression. More importantly, they help you look like yourself on your best professional day.
The Science Behind Smiling in a Headshot
Generally, smiling helps because it signals approachability. Nevertheless, not all smiles create the same impression.
Photofeeler analyzed more than 60,000 ratings across 800 profile photos and found that a smile with visible teeth produced gains in perceived competence, likability, and influence. However, the same research also found that an exaggerated laughing smile could increase likability while reducing perceived competence and influence. (Profiled)
That distinction is important. A warm, natural smile can make you look confident and human. However, a forced grin can make the image feel less polished. Similarly, a flat or overly serious expression can work in some industries, but it may also create distance.
Research on smiles and trust also shows that the eyes matter. A PubMed-indexed study found that trustworthiness judgments are influenced not just by the smiling mouth, but by the eye expression. In other words, the smile needs to reach the eyes to feel genuine. (PubMed)
Because of that, the best headshot smiles are rarely created by saying “cheese.” Instead, they come from coaching, conversation, and timing.
H2: The Best Smile Is Usually the One That Feels Natural
A professional headshot should not look like a school photo. It should feel alive. Therefore, the best expression is often captured between poses, not during a stiff command.
PetaPixel’s headshot posing guidance recommends trying different expressions during a session, including smiles, so clients can compare options afterward. It also notes that real emotion helps the smile show in the eyes. (PetaPixel)
Likewise, Fstoppers emphasizes that studio headshots require more than lighting and composition. The photographer needs to understand the client’s profession, goals, and comfort level. That makes it possible to tailor the session to the person rather than forcing everyone into the same expression. (Fstoppers)
This is where professional photography becomes especially valuable. A DIY photo may capture your face. However, a professionally directed headshot captures your message.
Should Corporate Professionals Smile?
For corporate professionals, the answer is usually yes. However, the smile should feel measured, confident, and polished.
A corporate headshot needs to communicate competence first. Nevertheless, it should not make the person appear cold. Research on workplace impressions has long emphasized two central dimensions: warmth and competence. In one organizational behavior paper, Amy Cuddy, Peter Glick, and Anna Beninger describe warmth and competence as fundamental traits that shape professional judgments, including hiring and workplace evaluation. (ScienceDirect)
For executives, consultants, managers, and entrepreneurs, a slight-to-medium smile often works best. It says, “I am capable, but approachable.” Additionally, it helps reduce the overly formal tone that can make a corporate profile feel dated.
Best expression for corporate headshots
A confident closed-mouth smile or a relaxed smile with teeth usually works well. However, the expression should not feel overly casual. The shoulders should stay strong, the eyes should stay engaged, and the lighting should flatter the face without making it look harsh.
For clients booking business headshots in Long Beach, LA County, or Orange County, this balance matters. Many professionals need the same headshot to work across LinkedIn, company websites, press releases, speaking bios, and conference materials.
Should Lawyers and Financial Professionals Smile?
Lawyers, financial advisors, accountants, and executives in conservative fields often worry that smiling will make them look less serious. That concern is understandable. However, a neutral expression is not automatically more professional.
In fact, TIME’s career guidance cites a recruiter who recommends smiling in a LinkedIn photo because it helps people appear more approachable. (Time)
For law and finance, the best answer is usually a controlled smile. A huge grin may not match the tone of a litigation attorney, wealth advisor, or corporate counsel. However, a slight smile with direct eye contact can communicate trust, discipline, and confidence.
Best expression for law and finance
A subtle smile, relaxed mouth, and focused eyes usually work best. Additionally, the wardrobe should support authority. A well-fitted suit, clean background, and professional lighting can help the expression feel credible rather than casual.
This is exactly why professional headshots are so important. In serious industries, small details carry a lot of weight. A weak crop, poor lighting, shiny skin, or awkward smile can undermine the message.
Should Healthcare Professionals Smile?
For healthcare providers, a smile is often essential. Patients want competence, but they also want reassurance.
A 2026 Decision Support Systems study on physician profile images found that image clarity, smile intensity, and medical professionalism positively affected patient selection behavior. The study also noted that profile images are easy-to-process visual cues for patients choosing providers online. (ScienceDirect)
Because of that, doctors, dentists, therapists, chiropractors, veterinarians, and wellness professionals usually benefit from a warm smile. However, the smile should still feel calm. Patients do not need a salesy expression. Instead, they need to see someone who looks skilled, present, and trustworthy.
Best expression for healthcare headshots
A gentle, genuine smile with relaxed eyes works especially well. Additionally, a clean background, soft lighting, and professional wardrobe help reinforce credibility. For group healthcare teams, consistency across staff headshots also helps the practice look more organized and reliable.
Should Real Estate Agents and Sales Professionals Smile?
For real estate, sales, hospitality, recruiting, and client-facing roles, smiling is usually a major advantage. These industries depend on trust, comfort, and relationship-building.
A profile photo is not just a professional ID. It is part of the client’s decision-making process. Therefore, the expression should make someone feel comfortable reaching out.
Forbes also reported on research showing that smiling with visible teeth in LinkedIn photos can increase perceptions of competence, influence, and likability. (Forbes)
For sales professionals, that matters. A strong smile can make a person appear more open and easier to contact. However, the expression still needs control. A polished headshot should not feel like a vacation snapshot.
Best expression for sales and real estate
A confident smile with teeth often works well. Meanwhile, the pose should stay professional. Clean lighting, intentional background choice, and strong posture help the image feel warm without becoming too casual.
Should Creative Professionals Smile?
Creative professionals have more flexibility. Artists, designers, photographers, filmmakers, actors, writers, stylists, and marketing professionals can often use a more expressive headshot.
However, flexibility does not mean randomness. A creative headshot still needs strategy. It should communicate personality while staying aligned with the brand.
Fstoppers notes that a successful portrait session benefits from a range of expressions because every person expresses themselves differently. (Fstoppers)
For creative industries, that variety is powerful. You may need one smiling image for LinkedIn, one thoughtful image for a speaker bio, and one more expressive portrait for your website. Therefore, a professional headshot session should create options.
Best expression for creative professionals
A natural smile, thoughtful half-smile, or expressive look can all work. However, the final choice should match the platform. A filmmaker’s website portrait may be moodier. A marketing consultant’s LinkedIn headshot may need more warmth.
Should Tech Professionals Smile?
Tech professionals often lean toward simple, minimal headshots. That can work well. However, a completely blank expression may not be ideal, especially for founders, product leaders, consultants, and team-facing roles.
WIRED’s interview with Amy Cuddy highlights that first impressions often involve judgments of both trustworthiness and competence. (WIRED)
That combination matters in tech. A founder needs to look credible to investors. A product manager needs to look collaborative. A developer may want to appear focused, but still approachable.
Best expression for tech headshots
A small, confident smile often works best. Additionally, modern lighting and a clean background can help the portrait feel current. For startup teams, consistent business headshots can also make the company look more established.
Should Executives Smile?
Executives should usually smile, but the smile must be intentional. A CEO, founder, board member, or senior leader needs to project authority. Nevertheless, authority without warmth can feel distant.
The strongest executive headshots often combine a composed expression with slight warmth. This might be a small smile, a relaxed mouth, or a confident smile with restrained energy. As a result, the image feels powerful without becoming unapproachable.
Best expression for executive headshots
A slight-to-medium smile with direct eye contact is usually ideal. Additionally, professional lighting should sculpt the face, define the jawline, and keep the eyes bright. These details are difficult to achieve consistently with DIY photography.
When a Serious Expression Works Better
Although smiling is often the strongest choice, serious expressions still have a place. For example, authors, actors, executives, artists, public speakers, and certain legal or financial professionals may need a more contemplative look.
However, serious does not mean tense. The face should still feel engaged. The eyes should connect. The posture should remain open.
A serious headshot fails when it looks uncomfortable. It succeeds when it feels calm, confident, and intentional.
The difference between serious and stiff
A stiff expression looks like the person is waiting for the photo to end. A strong serious expression looks like the person has presence. Therefore, professional direction is crucial. The photographer must know how to coach the mouth, eyes, chin, shoulders, and breathing.
Why DIY Headshots Often Miss the Expression
DIY headshots can be useful in emergencies. However, they often fall short because expression is hard to judge on yourself.
Photofeeler’s LinkedIn photo guidance notes that people are often poor judges of their own best profile pictures. It also warns that overediting can make a profile image look unnatural. (Profiled)
Additionally, DIY photos usually struggle with lighting, lens distortion, background distractions, and awkward posing. LinkedIn advises avoiding blurry, low-resolution images and recommends having someone else take the photo instead of relying on a selfie. (LinkedIn)
A professional headshot photographer solves those issues before they become problems. More importantly, they help you find the expression that fits your industry.
How a Professional Photographer Helps You Find the Right Smile
A strong headshot session is not about forcing everyone to smile the same way. Instead, it is about coaching expression until the person looks natural, confident, and aligned with their field.
A professional photographer may capture several versions: neutral, slight smile, closed-mouth smile, smile with teeth, and a more expressive option. Then, the client can compare them in real time or after the session.
This matters because different platforms need different tones. A LinkedIn headshot may need warmth. A company bio may need polish. A speaker photo may need energy. A press photo may need authority.
For Headshots By Sam, this is especially important because clients come from many industries across Long Beach, LA County, Orange County, the West Coast, and all across the United States. Therefore, the goal is never one-size-fits-all. The goal is to create professional headshots that support the client’s real-world goals.
