Leading Lines – composition technique using lines to guide the viewer’s eye into a part of the scene. Learn how to use leading lines here.

Lightroom – image management and editing software by Adobe. Allows you to organise your photography into folders, make global edits, and perform batch actions. Check out our course on Lightroom.

Light drawing / Light painting – long exposure technique that causes light to trail into lines.

Light Leak – A light leak is a photographic artefact caused by unintentional exposure to light leaks or stray light entering the camera body or film cassette, resulting in streaks, flares, or fogging effects on the final image. Light leaks can occur due to worn seals, loose parts, or accidental opening of camera backs during film loading or processing.

Light meter – A light meter is a device that measures the scene’s luminosity to determine the best exposure value. Most cameras have a built-in light meter that relies on reflective readings through the lens.

Live View – Live view is a feature found in many digital cameras that allows photographers to preview and compose their shots using the camera’s LCD screen in real-time, rather than through the optical viewfinder. When the live view is activated, the camera’s image sensor continuously feeds a live video feed to the LCD screen, showing exactly what the sensor sees.

Light meter – The device that measures the light in a scene to give the optimum exposure value. Cameras have in-built light meters, but in a studio, you use a hand-held light meter to gauge the exposure needed for a lighting set-up.

Long Exposure – A technique using a long shutter speed allowing light to enter the camera over a longer period of time. This will cause any moving objects to blur whilst keeping still objects still. Generally achieved whilst using a tripod. Click here to learn more about long exposures.

Lens – A lens is a transparent optical element used in cameras and other optical devices to focus light onto a photosensitive surface, such as a camera sensor or photographic film. Camera lenses consist of multiple glass or plastic elements arranged in specific configurations to control the direction, angle, and magnification of light rays, resulting in sharp, clear images.

Landscape Photography – Landscape photography is a genre of photography that focuses on capturing scenic views, natural landscapes, and outdoor environments. Want to capture landscapes like a pro? Check out our full course here.

Lens Hood – A lens hood is a cylindrical or petal-shaped accessory attached to the front of a camera lens to reduce unwanted light and glare, improve contrast, and protect the lens from damage. Lens hoods help prevent lens flare, ghosting, and veiling glare caused by stray light entering the lens from off-axis angles, ensuring optimal image quality and clarity.

Luminosity – Luminosity refers to the brightness or intensity of light emitted or reflected by a subject, surface, or light source. In photography, luminosity affects exposure settings and image appearance, influencing factors such as contrast, shadow detail, and overall tonal range. Luminosity can be measured and adjusted using light meters, exposure controls, and image editing software.

Lens Flare – Lens flare is an optical phenomenon characterized by unwanted artifacts or patterns of scattered light and reflections that appear in photographs, typically caused by direct sunlight or bright light sources entering the camera lens at oblique angles. Lens flare can manifest as coloured streaks, circles, or haze in images, reducing contrast and image quality.

Light Painting – Light painting is a photographic technique that involves using handheld light sources, such as flashlights, LED lights, or sparklers, to create deliberate patterns, shapes, and designs in a long exposure photograph. Light painters “paint” with light in a dark environment, moving the light source across the scene to capture streaks, trails, and illuminated subjects in the final image.

Low-Key – Low-key photography is a lighting technique that uses dark tones, shadows, and mood lighting, with minimal bright highlights or mid-tones. Low-key images often evoke a sense of mystery, drama, or suspense, using contrast and selective lighting to emphasize shape, texture, and form in the subject.

Lens Compression – Lens compression refers to the optical effect produced by telephoto lenses that visually compress the apparent distance between objects in a scene, making distant subjects appear closer together and enhancing the perception of depth and scale. Lens compression is commonly used in landscape, wildlife, and portrait photography to emphasize perspective and create impactful compositions.

Lens Distortion – Lens distortion is an optical aberration that occurs when camera lenses bend light rays unevenly, resulting in geometric distortion, perspective distortion, or chromatic aberration in images. Common types of lens distortion include barrel distortion (bulging or curving of straight lines), pincushion distortion (converging or bowing of straight lines), and chromatic aberration (colour fringing or colour distortion).

Lensbaby – Lensbaby is a brand of speciality camera lenses known for their unique optical effects and creative photography capabilities. Lensbaby lenses feature selective focus optics, flexible lenses, and tilt-shift mechanisms that allow photographers to achieve artistic blur, bokeh, and distortion effects, creating dreamy, ethereal images with a distinctive look and feel.

Lens Correction – Lens correction is a digital image processing technique used to correct optical distortions and imperfections caused by camera lenses, such as distortion, vignetting, chromatic aberration, and perspective distortion. Lens correction software analyses image metadata and applies corrective adjustments to compensate for lens characteristics and improve overall image quality.

Large Format – Large format photography refers to the use of photographic equipment that captures images on large-format film or digital sensors, typically larger than 4×5 inches (or 102×127 mm) in size. Large format cameras offer superior image quality, resolution, and detail compared to smaller formats, making them popular for architectural photography, landscape photography, and fine art prints.

LCD Screen – An LCD (Liquid Crystal Display) screen is a type of flat-panel display used in digital cameras and electronic devices to preview images, display menus, and provide visual feedback. LCD screens use liquid crystal cells illuminated by a backlight to produce images and graphics, offering high-resolution displays with vibrant colours and sharp detail.

Lens Mount – A lens mount is a mechanical interface or attachment mechanism used to connect interchangeable lenses to camera bodies securely. Lens mounts vary between camera manufacturers and models, with different designs, dimensions, and electrical contacts to ensure compatibility between lenses and camera bodies.

Layer Mask – A layer mask is a non-destructive editing tool used in digital image editing software to selectively control the visibility and transparency of specific areas within a layer. Layer masks allow photographers to apply adjustments, filters, and effects to targeted areas of an image without permanently altering the original pixels, enabling precise and flexible image editing workflows.
