AI headshot generators are incredible tools, but they have one limitation: they can only work with what you give them. The quality of your output depends heavily on the quality of your input photo. Feed it a blurry, poorly lit selfie and you will get a polished but still blurry, poorly lit headshot. Give it a clean, well-taken photo and the results can be almost indistinguishable from a professional studio session. If you are thinking about creating a professional headshot with AI, the first thing to get right is picking the right starting photo. Here is a practical guide to choosing the best selfie for Photos To Photos and other AI headshot tools.
Lighting Is the Single Most Important Factor
Good lighting does more for your photo than any AI enhancement ever could. AI headshot tools can fix backgrounds, adjust composition, and even change your outfit, but they struggle to reconstruct details that were lost in shadows or blown out by harsh light.
The ideal lighting setup is soft and even, coming from in front of you. A window on a cloudy day is perfect — the diffused light wraps around your face naturally, reducing harsh shadows under your nose and chin. If you are shooting at home, avoid overhead ceiling lights, which cast unflattering shadows. Instead, position yourself facing a large window, with the light at eye level if possible.
Avoid direct sunlight. It creates harsh shadows and can make you squint. If you have to shoot in sunlight, find a shaded spot outdoors where the light is still bright but diffused. Ring lights work well too — just keep them at arm's length, not right next to the camera lens, to avoid the flat "deer in headlights" look.
Resolution and Image Quality Matter More Than You Think
AI headshot generators work best with high-resolution source images. A photo taken with your phone's rear camera (not the selfie camera) will give much better results because rear cameras have higher resolution, better sensors, and more accurate color reproduction. If you have to use the front camera, make sure you are in good light and hold the phone steady.
Your source image should be at least 1000 pixels on the shortest side. Anything smaller than that and the AI has to guess too much detail, resulting in a soft or slightly blurry headshot. Also, avoid heavily compressed images — photos sent through messaging apps like WhatsApp or Messenger are often compressed to a fraction of their original quality. Transfer the original file from your phone to your computer using a cable, AirDrop, or cloud storage for the best quality.
Facial Expression: Go Neutral or Slightly Smiling
AI headshots look most natural when your expression is relaxed and genuine. A slight smile that reaches your eyes — often called a "half-smile" or "Mona Lisa smile" — works well for most professional contexts like LinkedIn, company websites, and resume photos. It conveys approachability without looking forced.
Avoid extreme expressions. A wide, toothy grin can look unnatural after the AI processes it, especially if your smile changes the shape of your eyes or cheeks significantly. Similarly, a completely neutral, expressionless face can come across as cold or unapproachable in the final result. The sweet spot is a relaxed, natural smile — think of how you look when you greet someone you like.
Camera Angle and Framing
Your selfie should be taken at eye level or slightly above. Photos taken from below (looking up at the camera) emphasize the jaw and nostrils, which rarely looks flattering. From above (looking down at the camera) can make you look smaller and less confident. Eye level is the most natural and universally flattering angle.
Frame your face and shoulders. Leave some space above your head — about a hand's width — so the AI has room to work with backgrounds and cropping. Your shoulders should be squared to the camera but relaxed, not hunched. Turn your body slightly at a 45-degree angle to the camera for a more natural, dimensional look. Some of the best professional headshot generator results come from photos where the subject is turned slightly, not facing the camera straight on.
What to Avoid in Your Source Photo
Some photos simply do not work well as AI headshot sources:
- Group photos or selfies with another person — the AI may merge features or get confused about which face to focus on
- Photos with heavy filters — beauty filters, Snapchat face distortions, or Instagram filters alter your facial structure and the AI will amplify those distortions
- Hats or sunglasses — the AI needs to see your full face, especially your eyes and hairline, to generate an accurate headshot
- Wide-angle selfies — the lens distortion from wide-angle selfies (especially common on phone front cameras) makes your nose look larger and face shape distorted
- Strong backlighting — if the light source is behind you, your face will be underexposed and the AI will struggle to recover details
Multiple Shots Give You Options
Take 10-15 photos in one sitting with slight variations — different angles, different expressions, different lighting positions. Then pick the 2-3 best ones and run them through the AI headshot generator. Different source photos can produce surprisingly different results even with the same settings, so having options lets you choose the best final headshot. It takes five extra minutes and the results are worth it.
