  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A form of image compression when saving the image that discards data from it. Saving a picture as a JPEG uses lossy compression.






2. A lens with the ability to focus from infinity to extremely closely - allowing it to capture images of tiny objects in frame-filling - larger-than-life sizes.






3. CMYK - An acronym for the ink colors Cyan (process blue) - Magenta (process red) - Yellow and Black used in four-color process printing.






4. An image that is mainly made up of light tones - with relatively few mid-tones or shadows.






5. A digital camera analyzes a scene using its white balance mode to determine areas that should be recorded as pure white. The camera adjusts the overall scene's color balance so that the areas meant to be reproduced as white in the picture will be whi






6. Or - electronic noise. This is the grainy look you find in a digital image caused by image artifacts. It is usually noticeable in shadow areas - and generally produced when shooting in low light. Noise is almost always unwanted and unattractive.






7. Existing light surrounding a subject; the light that is illuminating a scene without any additional light supplied by the photographer. This is also called 'available light'.






8. Film speed or sensitivity is designated by a single - almost universally-accepted common system developed by the International Organization for Standardization which uses the initials 'ISO' before the film-speed number or digital camera's sensitivity






9. A lens aperture setting calibrated to an f-number






10. An acronym for Joint Photographic Experts Group that describes an image file format standard in which the size of the file is reduced by compressing it. JPEG - with its 16.7 million colors - is well suited to compressing photographic images. A 'JPEG'






11. Adding new pixels to a digital image between existing pixels. Interpolation software analyzes the adjacent pixels to create the new ones when enlarging an image file.






12. Refers to a million pixels - and is used in describing the number of pixels that a digital device's image sensor has.






13. A composition rule that divides the screen into thirds horizontally and vertically - like a tic-tac toe grid placed over the picture on a television set. Almost all of the important information included in every shot is located at one of the four int






14. A clear - neutral filter that absorbs ultraviolet radiation - with no effect on visible colors. The skylight filter is a UV filter with a pale rose tinge to it.






15. Technique that involves taking a picture while moving the camera at a relatively slow shutter speed. It is almost always used when tracking a moving object - such as a race car - as it travels across the film plane. When properly carried out - the ob






16. Frames per second (fps) refers to the number of pictures that a camera is able to take in a second. A point-and-shoot camera typically shoots one or two pictures per second. Higher-end single lens reflex (SLR) cameras have much greater performance -






17. If you're hand holding your camera - your shutter speed should not be slower than the reciprocal of your effective focal length (but not lower than 1/50th of a second) in order to avoid 'camera shake -' i.e. the blur that results from any slight move






18. A complementary color is one of a pair of primary or secondary colors that are in opposition to each other on a color wheel.






19. Adding new pixels to a digital image between existing pixels. Interpolation software analyzes the adjacent pixels to create the new ones when enlarging an image file.






20. The visible light spectrum is scientifically described in terms of color temperature - and is measured in degrees Kelvin (K). The range for Kelvin on a pro digital camera is approximately 2000-10000.. These K settings are the scientific numbers behin






21. A complementary color is one of a pair of primary or secondary colors that are in opposition to each other on a color wheel.






22. Occurs when an image editing program is used to change an image's size. Increasing an image's size requires the addition of new pixels and decreasing size removes pixels.






23. A lens with the ability to focus from infinity to extremely closely - allowing it to capture images of tiny objects in frame-filling - larger-than-life sizes.






24. Occurs when an image editing program is used to change an image's size. Increasing an image's size requires the addition of new pixels and decreasing size removes pixels.






25. A fall-off in brightness at the edges of an image - slide - or print. Can be caused by poor lens design - using a lens hood not matched to the lens - or attaching too many filters to the front of the lens. It can also be applied after the image is ta






26. A fall-off in brightness at the edges of an image - slide - or print. Can be caused by poor lens design - using a lens hood not matched to the lens - or attaching too many filters to the front of the lens. It can also be applied after the image is ta






27. Film speed or sensitivity is designated by a single - almost universally-accepted common system developed by the International Organization for Standardization which uses the initials 'ISO' before the film-speed number or digital camera's sensitivity






28. An accessory that attaches as a collar to the front of a lens to prevent stray light from striking the surface of the lens - causing flare






29. Graininess occurs when clumps of individual grains are large and irregularly spaced out in the negative. They are visible to the naked eye in the finished print - particularly enlargements - as sand-like particles. When this occurs - the picture appe






30. Graininess occurs when clumps of individual grains are large and irregularly spaced out in the negative. They are visible to the naked eye in the finished print - particularly enlargements - as sand-like particles. When this occurs - the picture appe






31. The time an hour or less before the sun goes down and around fifteen minutes after the sun has set. Sunlight is usually warmer and more complimentary to skin tones at this time - and the angle of the light can provide depth to portraits and landscape






32. Lens with a focal length approximately equal to the diagonal of the film format or of a digital camera's image sensor. A scene viewed through a normal lens appears to have the same perspective as if it was being viewed 'normally' without a lens - jus






33. Describes a mostly dark image - with few highlights.






34. Commonly abbreviated as 'TTL'. Refers to both exposure metering of the light passing through the lens (Through-the-lens metering - and TTL flash metering) and viewing a scene through the same lens that allows light to reach the sensor or the film (Th






35. In a studio - the main light is placed fairly high - directly in front of the face - aimed at the center of the nose. It casts a shadow shaped like a butterfly beneath the nose.






36. An image file type created in Adobe PhotoShop that results in pictures that are viewable with Adobe Acrobat - so someone (Mac or PC-user) who doesn't have PhotoShop can still view the image. It is often used in forms creation and for documents that r






37. A million bytes - abbreviated as MB - Mb and sometimes Mbyte. Technically and more precisely - it refers to 1 -048 -576 bytes. Digital images are often referred to in terms of their 'size in Mb'.






38. A lens in which focal length is variable. Elements inside a zoom lens shift their positions - enabling the lens to change its focal length - in effect - providing one lens that has many focal lengths. (Also called a 'Variable focus lens.')






39. A shutter speed dial setting that indicates that the shutter will remain open as long as the release button is depressed - also known as the 'B setting ' or 'Bulb' setting. The 'B' setting is used for time exposures.

41. A contract in which a model consents to the use of his or her images by the photographer or a third party. Sometimes referred to simply as a 'release.'






42. Any device used to reflect light onto a subject.






43. Occurs when the photographer incrementally lights an otherwise darkened scene using a handheld flashlight or other small light source while the shutter remains open during a time exposure. The light is added to the scene in the manner of an artist us






44. (Graphics Interchange Format) is a small image file format that supports transparency and is constrained to a maximum of 256 colors - generally making it a poor choice for your digital images. When it was created - most computer video cards were able
