Headshot & Photography Glossary
Clear, jargon-free definitions of the headshot and portrait-photography terms you will run into — so you always know exactly what they mean.
A
- AI Headshot
- A professional-looking portrait generated by artificial intelligence from one or more photos of a person, rather than captured in a traditional photo shoot. The AI reconstructs the subject in a polished setting with studio-style lighting and a clean background. Quality depends heavily on the source photos provided. Create an AI headshot
- Aspect Ratio
- The proportional relationship between an image's width and height, written as two numbers such as 1:1 or 3:4. Different platforms favor different ratios — square 1:1 suits profile pictures, while a slightly taller 3:4 is common for headshots and LinkedIn. Choosing the right ratio avoids awkward cropping later.
B
- Backlighting
- Light that comes from behind the subject, facing the camera. Strong backlighting turns a face into a dark silhouette and is a common reason a portrait looks underexposed. For headshots, front or side lighting is almost always more flattering.
- Bokeh
- The soft, pleasing blur of the out-of-focus areas in a photograph, especially background highlights that render as smooth circles of light. Bokeh comes from a shallow depth of field and helps separate the subject from the background. It is a hallmark of the professional, portrait-lens look.
C
- Candid
- A photograph taken spontaneously, without the subject posing or being formally directed. Candid shots capture natural expressions and moments, in contrast to the deliberately composed nature of a headshot. They often feel more relaxed and authentic.
- Catchlight
- The small reflection of a light source visible in a subject's eyes. Catchlights make eyes look bright, alive, and engaged, and their absence can make a portrait feel flat or lifeless. Photographers position lights specifically to create them.
- Corporate Headshot
- A polished, professional portrait used in business contexts such as company team pages, executive bios, and directories. Corporate headshots typically feature business attire, a neutral background, and consistent styling across a team. Consistency matters most when an entire organization needs matching photos.

D
- Depth of Field
- The range of distance in a scene that appears acceptably sharp. A shallow depth of field keeps the subject in focus while the background falls into a soft blur, which is the classic portrait look. A deep depth of field keeps both foreground and background sharp.
- DPI / PPI
- DPI (dots per inch) and PPI (pixels per inch) describe how densely an image's detail is packed when printed or displayed. Higher values mean finer detail, with 300 DPI being the common standard for sharp printed photos. Screens generally need far less density than print.
E
- Environmental Portrait
- A portrait that deliberately includes the subject's surroundings — such as an office, studio, or workshop — to give context about who they are and what they do. Unlike a tightly cropped headshot, the environment is part of the story. It is common for founder and creative profiles.
F
- Fill Light
- A secondary, softer light used to brighten the shadows created by the main (key) light. Fill light controls contrast so that the shadowed side of a face does not go too dark. Balancing key and fill light is central to flattering portrait lighting.
G
- Golden Hour
- The short period shortly after sunrise or before sunset when sunlight is warm, soft, and low in the sky. The flattering, diffused light of golden hour is prized for portraits because it minimizes harsh shadows. It contrasts with the hard, overhead light of midday.
H
- Headroom
- The amount of empty space between the top of a subject's head and the top edge of the frame. A small, balanced amount of headroom keeps a portrait from feeling cramped or top-heavy. Too much makes the face look small; too little crops the head awkwardly.
- Headshot
- A photograph focused tightly on a person's face and the top of their shoulders, used to clearly show what someone looks like. Headshots are the standard for professional profiles, resumes, and team pages. The emphasis is on a clear, flattering view of the face rather than the body or surroundings.
K
- Key Light
- The main, dominant light source in a portrait, which establishes the overall direction and character of the lighting. Its position relative to the face determines where highlights and shadows fall. Most other lights, such as fill and rim lights, are balanced against the key light.
P
- Passport Photo
- A strictly regulated portrait used for passports and other official identity documents. Requirements typically include a neutral expression, a plain light-colored background, even lighting with no shadows, and the full face clearly visible and centered. Exact rules on size and framing vary by country, so always check official guidance.
- Profile Photo
- The image that represents a person on a social or professional platform, often displayed as a small circle or square. Because it appears at thumbnail size next to your name, a profile photo should be tightly framed on the face and instantly recognizable. It is one of the most common uses for a headshot.

- Prompt
- The text instruction given to an AI model that describes the desired output, such as the style, setting, or mood of an image. In headshot tools the prompt is often handled by a chosen style preset, though some flows let you refine it directly. A clear, specific prompt produces more predictable results.
R
- Resolution
- The amount of detail an image contains, usually measured in pixels (width by height). Higher resolution means a larger, sharper image that holds up when enlarged or printed. Low-resolution images look soft or pixelated when scaled up beyond their native size.
- Retouching
- The process of refining a photograph after it is taken — smoothing skin texture, evening out tone, and removing minor blemishes — while keeping the subject looking natural. Good retouching is subtle and preserves a person's real features. Heavy-handed retouching can make a portrait look artificial.
- Rim Light
- A light placed behind or to the side of a subject that creates a bright outline along their edges, separating them from the background. Also called a hair or separation light, it adds depth and a polished, three-dimensional feel. It is a common element of studio portrait setups.
- Rule of Thirds
- A composition guideline that divides the frame into a three-by-three grid and places key elements along the lines or at their intersections. Positioning the eyes along the upper third line, for example, tends to create a balanced, engaging portrait. It is a guideline rather than a strict rule.
S
- Style Preset
- A predefined combination of setting, lighting, attire, and mood that determines the look of a generated headshot — for example Executive, Corporate, or Dating Profile. Choosing a preset is the simplest way to control the final style without writing a detailed prompt. Each preset is tuned for a particular use case. Browse styles
T
- Three-Quarter Shot
- A portrait that frames the subject from roughly the head to the waist or mid-thigh, showing more of the body than a tight headshot. It offers a balance between facial detail and a sense of posture and presence. The term can also describe a face turned partway toward the camera.
U
- Upscaling
- Increasing the pixel dimensions of an image to make it larger and higher resolution, ideally while keeping edges and detail sharp. Modern upscaling uses AI to add plausible detail rather than simply stretching pixels. It is useful when you need a print-ready or higher-resolution version of a photo. Upscale an image
W
- Watermark
- A visible logo, text, or pattern overlaid on an image to indicate ownership or a preview state. Watermarks are often placed on sample images and removed in the final, paid version. They discourage unauthorized use of a photo.
- White Balance
- A camera setting that adjusts colors so that whites appear truly white under different light sources, removing unwanted color casts. Correct white balance keeps skin tones looking natural rather than too warm (orange) or too cool (blue). Mixed lighting is a common cause of off-looking colors.
