Barrel distortion describes a type of distortion wherein lines that are straight in real life appear to curve inwards (like the walls of a barrel). A good way to check for barrel distortion is to look for parallel lines in the area you are shooting and see if the lines appear parallel in your image.

# data[].attributes.body
Pincushion distortion is the exact opposite of barrel distortion – straight lines are curved outwards from the center. This type of distortion is commonly seen on telephoto lenses, and it occurs due to image magnification increasing towards the edges of the frame from the optical axis.

# data[].attributes.body
ISO is your camera's sensitivity to light as it pertains to either film or a digital sensor. A lower ISO value means less sensitivity to light, while a higher ISO means more sensitivity.

# data[].attributes.body
The ASA (American Standards Association) scale is an arbitrary rating of film speed; that is, the sensitivity of the film to light. If everything else is kept constant, the required exposure time is inversely proportional to the ASA rating.

# data[].attributes.body
An image sensor is a device that allows the camera to convert photons – that is, light – into electrical signals that can be interpreted by the device.

# data[].attributes.body
Film grain is the visible silver crystals in a film negative's emulsion. These light-sensitive silver halides change into pure metallic silver when exposed to light, which is how an image is captured on film.

# data[].attributes.body
In digital photographs, the term noise refers to a certain type of visual distortion. It looks similar to grain found in film photographs, but can also look like splotches of discoloration when it's really bad, and can ruin a photograph.

# data[].attributes.body
Aperture refers to the opening of a lens's diaphragm through which light passes. ... Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures.

# data[].attributes.body
F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it's measured in f-stops.

# data[].attributes.body
Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. ... Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. Additionally, it could be defined as the distance from the focal point of a lens or mirror to the reflecting surface of the mirror or the centre point of the lens.

# data[].attributes.body
Depth of field refers to how much is in focus in front of and behind the subject that is focused upon. “More” depth of field means that more is in focus. “Shallow” depth of field means that very little is in focus other than the subject. The photographer focuses specifically on one object or part of an object.

Automatic Exposure is when the camera chooses the optimum shutter speed, aperture, ISO and flash settings for your shot. All you need to do is point and shoot.

# data[].attributes.body
Manual mode stands for a full manual control of Aperture and Shutter Speed. In this mode, you can manually set both the aperture and the shutter speed to any value you want – the camera lets you fully take over the exposure controls.

# data[].attributes.body
Aperture Priority: The “A” setting on your camera gives priority to the aperture. Based on the f-stop at which it's set, the camera chooses a corresponding shutter speed to provide good exposure. The given aperture determines the amount of depth of field in the photo.

# data[].attributes.body
Shutter priority (usually denoted as S on the mode dial), also called time value (abbreviated as Tv), refers to a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.

# data[].attributes.body
The "program" in Program mode refers to the fact that you can fiddle with the shutter speed and aperture combo. Whether you choose Auto or Program, the camera chooses an aperture and shutter speed combination that will give you a good exposure.

# data[].attributes.body
Shutter speed is exactly what it sounds like: It's the speed at which the shutter of the camera closes. A fast shutter speed creates a shorter exposure — the amount of light the camera takes in — and a slow shutter speed gives the photographer a longer exposure.

# data[].attributes.body
Bulb Mode is an exposure setting that is used when seeking to use a shutter speed of more than 30 seconds. Generally, this would be used in extremely low light situations, such as taking photos of the night sky.

# data[].attributes.body
What Is Motion Blur? In photography, motion blur is the purposeful streaking or blurring of an object in motion in a photo for visual effect. It's a great technique for capturing movement in a still image, and is often used in both nature photography and sports photography.

A tripod is a portable three-legged frame or stand, used as a platform for supporting the weight and maintaining the stability of the camera.

# data[].attributes.body
Camera shake is a term used to define the act of accidentally shaking a camera during shooting due to unsteady hands, which results in blurry images. This generally occurs more often if you're shooting on a low shutter speed or with a heavy lens, and can be avoided by using a tripod and cable release setup.

# data[].attributes.body
Long exposure photography is a photographic technique that uses a slow shutter speed to flood a camera's image sensor with light. Most photography styles use a rapid shutter speed, but long exposure images require the shutter to remain open for one second or longer.

# data[].attributes.body
Time-lapse photography is a technique in which the frequency at which film frames are captured is much lower than the frequency used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing.

18% grey comes from the world of print, and is based on reflection. An 18% grey card reflects back 18% of the light that hits it. And it is actually the geometric mean between white paper (95% reflective) and black ink (3.5% reflective).

# data[].attributes.body
Spot metering allows the camera to measure the light reflected from the person's face and expose properly for that, instead of adjusting exposure for the much brighter light around the hairline. With the face properly exposed, the area around the back and hairline will become over-exposed.

# data[].attributes.body
Partial metering covers only the centre 6.2% of the frame in the viewfinder, thus providing precise metering only for the subject. When the background is brighter than the subject due to reasons like back lighting, this metering mode is particularly useful. It is useful for back-lit shots or tiny subjects.

# data[].attributes.body
Center-weighted metering evaluates the light in the middle of the frame and its surroundings and ignores the corners. Center-weighted Metering does not factor in the focus point you select, it only evaluates the middle area of the image.

# data[].attributes.body
Evaluative metering is the default metering mode on most cameras. It ensures that the camera will automatically adjust to the right exposure setting even when the ambient lighting shows greater contrast.

# data[].attributes.body
A mid-tone is precisely that – all luminance values that are not dark or light are considered to be mid-tones. Most of the time our camera meter will attempt to expose for this average brightness when in 'Automatic Mode. '

# data[].attributes.body
Highlights are the lightest elements in an image, whereas shadows are the darkest areas. Dynamic range is the ratio between those vivid highlights and dark shadows, from bright white to pure black. That range is key to an image's depth and drama. If a photo has poor dynamic range, the image can appear flat or gray.

# data[].attributes.body
A shadow is where there is a difference between a specific light intensity and a specific lower light intensity next to it. The difference in light intensity between the two light levels creates a contrast that our eye can see.

# data[].attributes.body
A vignette is a darker border - sometimes as a blur or a shadow - at the periphery of photos. It can be an intentional effect to highlight certain aspects of the image or as a result of using the wrong settings, equipment or lens when taking a photo.

# data[].attributes.body
Sepia photography is similar to black-and-white photography in that it's monochromatic, meaning one tone or one color. ... While traditional black-and-white photographs use a standard grayscale to create highlights and shadows, sepia-toned photos use a reddish-brown tone to create that spectrum.

Bracketing is a technique where a photographer takes shots of the same image using different camera settings. This gives the photographer multiple variations of the same image to choose from or combine to ensure that they get the perfect shot.

# data[].attributes.body
The exposure level indicator shows you what you have set in terms of exposure compensation and/or auto exposure bracketing. It is only shown in exposure modes that use exposure compensation or auto exposure bracketing. The scale on the side shows the measurement from the light meter based on the current exposure parameters.

# data[].attributes.body
Exposure compensation is used to alter exposure from the value selected by the camera, making photographs brighter or darker. ... Exposure is a matter of personal preference, and an exposure brighter or darker than that selected by the camera may sometimes better reflect the photographer's intent.

# data[].attributes.body
A white balance card (or gray card) helps you adjust the white balance and exposure settings of images by providing a reference point. The reference point prompts your camera to compensate for any white light on an image.
