Photography Final Exam Vocabulary
Terms in this set (52)
LCD (Liquid Crystal Display)
Shows you the picture you took.
The dial on the camera that changes your setting and speed of the shutter release. Some settings would be the "running man" which is used as sports mode or the "flower" which is used as a portrait mode.
C= Cyan , M= Magenta , Y= Yellow , K= Black
These colors are what make up the colors in the photos.
SLR (Single Lens Reflex)
Allows the photographer to see exactly what you captured.
Optical lens, which is used in conjunction with the camera body to make images. It has different "settings" that allow for short and long distances.
A storage device used for all photos taken. Can take out of camera, put into a card reader and upload the photos into the computer directly from the camera card.
Used instead of manually focusing your lens. AF button or setting on the mode button.
A mechanical device of a camera that controls the duration of a photographic exposure, as by opening and closing to allow light coming through the lens to expose a plate or film.
Built in Flash
Most cameras have this feature which allows extra light to hit your object. On most cameras you just "pop" it up or there is a button with a lightning symbol on it.
Should be used always when taking pictures; do not use the LCD screen (that is for viewing your pictures after taken)! The view finder will tell you when you are focused; usually you will see a red light and then a green light when you are focused on your object.
(also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Is a device that allows light to pass for a determined period, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene. A shutter of variable speed is used to control the exposure time of the film.
A camera setting corresponding to a particular f-number.
The time for which a shutter is open at a given setting.
F/Stop and Shutter Speed Together
Slow shutter speeds allow more light into the camera sensor and are used for low-light and night photography, while fast shutter speeds help to freeze motion. Examples of shutter speeds: 1/15 (1/15th of a second), 1/30, 1/60, 1/125. Aperture - a hole within a lens, through which light travels into the camera body.
The ISO system defines both an arithmetic and a logarithmic scale. The arithmetic ISO scale corresponds to the arithmetic ASA system, where a doubling of film sensitivity is represented by a doubling of the numerical film speed value.
In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop. See also shutter speed.
Setting on the camera that allows the user to take pictures in rapid succession. Most cameras will continue to take pictures as long as the shutter is depressed.
In photography, the metering mode refers to the way in which a camera determines the exposure.
A camera setting corresponding to a particular f-number.
Camera resolution is measured in megapixels (meaning millions of pixels); both image ﬁle resolution and monitor resolution are measured in either pixels per inch (ppi) or pixel dimensions (such as 1024 by 768 pixels); and printer resolution is measured in dots per inch (dpi) (see below).
Worms Eye View
A view of an object from below, as though the observer were a worm; the opposite of a bird's-eye view. A worm's eye view is used commonly for third perspective, with one vanishing point on top, one on the left, and one on the right.
Birds Eye View
Is an elevated view of an object from above, with a perspective as though the observer were a bird, often used in the making of blueprints, floor plans, and maps. It can be an aerial photograph, but also a drawing.
Depth of Field
In optics, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
Digital zoom is a function of a digital camera used to make the image seem more close-up. Digital zoom on a digital camera works the same as cropping and enlarging a photo in a graphics program.
Measures the sensitivity of the image sensor. The same principles apply as in film photography - the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds.
The most common horizontal line to be found in photographs and they often act as a dividing point in a photograph - in effect an anchor that the rest of the image is formed around.
The removal of the outer parts of an image to improve framing, accentuate subject matter or change aspect ratio.
Any of various processes of color photography wherein three primary colors (as blue-violet, green, and red in the additive process or magenta, yellow, and blue-green in the subtractive process) are used to produce the color of the subject photographed.
Is a tool that photographers use to direct viewers' attention to their subject.
Negative and Positive Space
Positive space refers to the main focus of a picture, while negative space refers to the background. When used creatively and intelligently, positive and negative space together can tell a story using visual composition alone.
Is the path the viewer's eye takes through the artwork, often to a focal area. It can also effect mood.
Visual clues in a two-dimensional image which give the impression of three-demensional space.
Close Up Lens
In photography, a close-up filter, close-up lens or macro filter is a simple secondary lens used to enable macro photography without requiring a specialised primary lens. They work identically to reading glasses, allowing any primary lens to focus more closely.
A unit of refractive power that is equal to the reciprocal of the focal length (in meters) of a given lens.
In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length.
A lens allowing a camera to change smoothly from a long shot to a close-up or vice versa by varying the focal length.
Rule of Thirds
Applied by aligning a subject with the guide lines and their intersection points, placing the horizon on the top or bottom line, or allowing linear features in the image to flow from section to section.
Formal balance can be defined as symmetrical balance. In the previous chapter, we taught you how to achieve symmetrical balance in photography. All you have to do is frame the shot so that one or more identical or similar subjects are repeated symmetrically on each side of a given point.
Foreground and Background
Foreground: the part of the photo that is the closest to the camera the branches in front of the park scene.
Background: the part of the photo that is farthest from the camera.
Lines and Imaginary Lines
In general, an imaginary line is any sort of line that has only an abstract definition, and does not exist. In fact, is used to identify the map properly. As a geographical concept, an imaginary line may serve as an arbitrary division (such as a border).
The ratio of a distance measured on a photograph or mosaic to the corresponding distance on the ground.
A flash is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K (Kelvin) to help illuminate a scene. A major purpose of a flash is to illuminate a dark scene.
Camera resolution is measured in megapixels (meaning millions of pixels); both image ﬁle resolution and monitor resolution are measured in either pixels per inch (ppi) or pixel dimensions (such as 1024 by 768 pixels); and printer resolution is measured in dots per inch (dpi)
Refers to the output resolution of a printer or imagesetter, and PPI (pixels per inch) refers to the input resolution of a photograph or image. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper.
Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level. ... The JPEG method is more often used for photographs, while the GIF method is commonly used for line art and other images in which geometric shapes are relatively simple.
Stands for "Joint Photographic Experts Group." JPEG is a popular image file format. Still, the compression algorithm is lossy, meaning some image quality is lost during the compression process.
TIFF is a flexible, adaptable file format for handling images and data within a single file, by including the header tags (size, definition, image-data arrangement, applied image compression) defining the image's geometry.
Is an image encoded in graphics interchange format (GIF), which contains a number of images or frames in a single file and is described by its own graphic control extension.
Is also an abbreviation for the Netware Printer Definition File. PDF (Portable Document Format) is a file format that has captured all the elements of a printed document as an electronic image that you can view, navigate, print, or forward to someone else.
Short for Universal Serial Bus, an external bus standard that supports data transfer. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards.
Is the generic term for an input device that reads flash memory cards. It can be a standalone device that connects to a computer via USB or it may be integrated into a computer, printer, or multifunction device.
