|A free digital asset management app that allows you to organize, select the individual images to import into image editing software, and rename or export images.
|Adobe Camera Raw
|Software that lets you import and enhance raw images.
|Any light that is available in a scene. It can be natural or artificial.
|Overall brightness of a scene.
Also known as “f-stop,” it is the opening in the camera lens that allows light to be recorded on the image sensor. It controls the depth of field and the intensity or amount of light that reaches the image sensor. A wide aperture (low f-stop) lets in more light, and a narrow aperture (high f-stop) restricts it.
|The light that comes from artificial sources.
|When the camera sharpens the image automatically.
|Type of third light in a three-light setup that separates the tones and subject from the background by adding depth and creating a pleasing glow or halo around the figure.
|The intentional overexposure and underexposure of an image by a photographer to capture a wider range of information for your image. This technique can capture details in highlights or shadows that might be otherwise lost and can be especially helpful during the editing process when you have a scene with a great variance of tones, such as backlit subjects, sunsets, night scenes, or landscapes with dramatic clouds.
|Early photographic process developed by William Henry Fox Talbot that included the creation of a paper negative and technology that involved the transformation of the negative to a positive image, allowing for more than one copy of the picture.
|A device that contains a small hole for light to pass through and projects an inverted image of an external object.
Early photographic process that involved fixing a substance known as gun cotton onto a glass plate, allowing for shorter exposure time than previous processes of three to five minutes and producing a clearer image.
The coordination of color across various devices from cameras, computers, and editing software to printers and the various paper types to ensure that the color and tones of your image are reproduced accurately.
|The range of colors shown in a photo.
|Also known as the principles of design. How the design elements are arranged to produce a specific effect.
|A document that shows all the images captured for a particular project.
|Also known as constant lights; lights that stay on during the photo shoot.
|Images free from unrealistic color casts, that have appropriate brightness in the mid-tones with details in both highlights and shadows, and have adequate contrast for the subject.
|Early historic photographic process developed by Louis Daguerre that significantly reduced exposure time needed to create an image and resulted in a lasting image.
|Depth of field
|The distance of focus or sharpness between the closest and farthest objects in a photograph, and is controlled by the aperture.
|Adjustment that permanently affects the pixels in an image. These types of edits cannot be undone once the file is saved and closed.
|Stands for digital negative files. It is the most universally used file format supported by Adobe
|The relationship between ISO, shutter speed, and aperture that produces the right balance of tones (or correct exposure) in an image. For any scene, there is a correct exposure determined by the amount of light available and the specific camera settings the photographer chooses. However, correct exposure is relative; you can adjust shutter speed, aperture, and ISO to capture the image you envision.
|The supporting light sources in a scene.
|Describes the optical capabilities of a camera lens and is represented in millimeters.
|Also known as the elements of design. The physical parts or visual components of a work. These include line, shape, mass/volume, perspective, texture, and color.
|The relationship of parts achieved when the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is thought to provide the most harmonious and visually pleasing proportions in art and architecture.
|Type of third light in a three-light setup that separates the subject from the background, adding dimension to the image.
|High key lighting
|Creates large white areas that are light and bright with white and grey tones that can translate to upbeat, youthful, or happy feelings.
|Feature in editing programs that shows the tonal distribution of the image.
|The resolution of the image.
|Medium for digital cameras that records an image.
|Stands for International Standard Organization. It is the numerical rating that describes the image sensor’s sensitivity to light. The ISO determines how much light is needed for correct exposure.
|The main light on a subject and the most powerful light in the scene.
|Part of the camera that collects light from an object and focuses it through to the recording medium.
|Device designed to create the most accurate light scenario for assessing prints.
|The relationship between the camera, the subject, and the light, which will impact where you add lights, and can be determined by the highlights and shadows present.
|The intensity or quality of light, the effect lights have on a particular scene.
The physical objects that emit light into the world.
|Low key lighting
|Produces large dark areas that can express somber, serious, or more formal tones.
|Allows the photographer to control the part of the image that is sharp.
|Represents the camera’s resolution. 1 million pixels = 1 megapixel (MP).
|Setting that determines how the light meter inside the camera measures exposure and amount of light available in the scene.
|Light produced by the sun and varies depending on the time of day and the season.
|Pixels are not discarded or lost in the editing process and the quality of the image is maintained.
Typically used to create a dramatic portrait or still life and is usually a low key lighting situation.
|Quality of lighting
|Determined by the light source and whether or not it is modified. Described by observing the highlights and shadows within a scene.
|Rule of thirds
|The placement of the subject at the intersection of the imaginary horizontal and vertical lines that divide the image into three parts.
|The time measured in fractions of a second that the shutter is opened, which determines the length of time the light hits the image sensor.
|The mechanism that controls the length of time that the image sensor is exposed to light.
|Lights that create short bursts of light and are the most powerful lights with bright intensity that most accurately replicate daylight in color temperature.
|Consists of a key light, a fill light, and one additional light best used to create a more balanced image with more light.
|The place from where you take a photograph, or the photographer’s perspective. An integral part of taking a photograph that can affect the angles, composition, and narrative of the image.
|The camera function that matches the temperature of light in a scene with the color recorded on the image sensor. Correct white balance produces a more accurate representation of color within an image.
|A sequence of steps needed to complete a project.
