Hotspot
A hotspot is an area in the image that is overly bright due to strong light reflection.
It often happens in product photography or glossy surfaces.
Hair Light
A type of lighting that is directed specifically at the subject’s hair to separate it from the background, providing a sense of depth and dimension in a portrait.
Halation
A halo or glow effect around bright areas in an image caused by light scattering within the camera or lens elements.
Half-Press

Handheld Light Meter
A portable device used to measure the amount of light in a scene, providing precise exposure information for accurate metering.
Handheld Light Reflector

Hard Copy
A physical printed copy of a photograph or image.
Hard Disk Drive (HDD)
A traditional mechanical storage device used to store digital image files, often found in computers and external storage devices.
Hard Drive Dock
A device that allows direct connection and access to internal hard drives externally, facilitating data transfer and backup.
Hard light
Hard light refers to direct and intense light that creates well-defined shadows and high contrast in a photograph. It typically comes from a small light source or when the subject is in direct sunlight.
Hard Shadow
A sharp, well-defined shadow cast by a light source with minimal diffusion or scattering.
Hardness (Lighting)
The quality of light that determines how abruptly the transition is from light to shadow, often influenced by the size and distance of the light source.
Haze Control Filter
A specialized filter used to minimize or eliminate haze and atmospheric scattering, enhancing the clarity and color saturation in landscape photography.
HDR (High Dynamic Range)
A technique that combines multiple exposures of the same scene to capture a wider range of tones and details, resulting in a final image with increased dynamic range.
Head-On Perspective
A photographic viewpoint where the camera is positioned directly in front of the subject, capturing it straight on without any oblique angles.
Headroom
The space or area above a subject’s head within the frame, allowing room for compositional balance or potential cropping in post-processing.
Headroom-to-Footroom Ratio
The balance between the amount of space above a subject’s head (headroom) and the amount of space below their feet (footroom) within a frame.
Common guideline
In most portraits:
- less footroom
- slightly more headroom (but not too much)
In full-body shots:
- balanced headroom and footroom
- or slightly more space at the bottom if the feet are important
Example
If you leave 10% space above the head, you might leave 10–15% space below the feet depending on the pose and story.
If the ratio is wrong:
- too much headroom → subject looks small or lost
- too much footroom → subject looks oddly placed and top-heavy
- too little headroom → subject feels cramped
Headshot
A headshot is a close-up photograph that focuses primarily on a person’s face, typically used for professional purposes like casting, business profiles, or social media.
Heliography
Heliography is an early photographic process invented by Joseph Nicéphore Niépce, using bitumen-coated plates exposed to sunlight, which produces the first permanent photographs.
High Contrast
The difference or range between the lightest and darkest areas in an image, resulting in a significant tonal difference between highlights and shadows.
High ISO
A high sensitivity setting on a digital camera that allows for capturing images in low-light conditions but may introduce digital noise.
High Key Portraits
Portraits where the lighting setup and tonal range emphasize bright and white tones, creating a soft and ethereal look.
High key
High key refers to a style of photography characterized by bright lighting and a predominantly light-toned color palette, resulting in low contrast and a soft, airy atmosphere.
High Pass Filter
A post-processing technique that enhances image sharpness by accentuating high-frequency details while suppressing low-frequency information.
High-Angle Shot
A perspective where the camera is positioned above the subject, looking down, often used to convey a sense of power, vulnerability, or diminishment.
Highlight Priority Mode
A shooting mode in some cameras that prioritizes retaining detail in highlight areas, often by slightly reducing overall exposure to avoid highlight clipping.
Highlights
The brightest areas of an image where the most light is reflected or transmitted, often representing the lightest tones in the photograph.
High-Resolution Image
An image with a high level of detail and fine clarity, typically achieved with cameras or sensors that have a large number of megapixels.
High-Speed Burst Mode
A camera shooting mode that allows for capturing a rapid series of images in quick succession, useful for capturing fast-moving subjects or action sequences.
High-Speed Photography
The practice of capturing rapidly occurring events by using fast shutter speeds, often involving specialized equipment and techniques.
High-Speed Sync (HSS)
A flash synchronization technique that allows the use of flash at high shutter speeds, enabling photographers to balance flash and ambient light in bright conditions.
Histogram
A graphical representation of the distribution of tones in an image, showing the range of brightness from shadows to highlights.
Histogram Clipping
A situation where the histogram of an image extends beyond the dynamic range of the sensor or display, resulting in loss of detail in the highlights or shadows.
Histogram Equalization
A technique used to adjust the tonal distribution of an image by stretching the histogram to improve contrast and highlight details.
Histogram Stretching
A technique used to adjust the tonal distribution of an image by stretching the histogram to increase contrast and maximize the use of the available tonal range.
Hologram
A three-dimensional photographic image produced using laser technology that can be viewed with a specific type of light or by tilting the image.
Honeycomb Grid
A grid-shaped attachment placed in front of a light source to create a more focused and directional light pattern.
Horizon Correction
A feature available in some cameras that automatically corrects the levelness of the horizon line in-camera, ensuring straight horizons in photographs.
Horizon Line
The line that separates the sky and the land or other elements in a photograph, typically running horizontally across the frame.
Hot Mirror Filter
A filter used to block or reduce infrared light in order to maintain accurate color reproduction in digital cameras.
Hot Pixel Mapping
A camera or software process that identifies and maps out hot pixels in an image, reducing their visibility and improving overall image quality.
Hot Pixel
A pixel on an image sensor that appears brighter or more colored than its surrounding pixels, often caused by sensor defects or high temperatures.
Hot Shoe Adapter
An accessory that allows the use of external flashes or other accessories with a camera that lacks a built-in hot shoe.
Hybrid Autofocus System
A camera autofocus system that combines phase detection and contrast detection methods, offering fast and accurate focusing on various shooting conditions.
Hybrid camera
A hybrid camera combines features of both digital and film cameras. It may refer to cameras that can shoot both digital stills and videos or those that support interchangeable lenses like DSLRs but lack a traditional mirror system.
Hybrid Sensor
A camera sensor that combines both traditional image sensor technology, such as CMOS or CCD, with additional features like on-sensor phase detection autofocus.
Hybrid Viewfinder Camera
A camera that offers both an electronic viewfinder (EVF) and an optical viewfinder (OVF), providing photographers with the flexibility to choose between the two.
Hyperfocal App
A mobile application that calculates the hyperfocal distance for a given aperture, focal length, and camera format, aiding photographers in achieving maximum depth of field.
Hyperfocal Distance
The closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp, maximizing depth of field.
Hot mirror
A hot mirror is an optical filter used in digital cameras to block infrared light from reaching the image sensor. It helps prevent color shifts and maintains accurate color reproduction.
Hue
Hue is a color property that distinguishes different colors on the color wheel. It refers to the dominant wavelength of light emitted or reflected by an object, determining its perceived color.
