Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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. 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.






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






3. An image file type created in Adobe PhotoShop. It is uncompressed and contains data on editing that is done to the image. A PSD file is essentially PhotoShop's version of a TIFF file. It lets you save a picture you are working on with its layers - ch






4. 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 -






5. The range of distance in a scene that appears to be in focus and will be reproduced as being acceptably sharp in an image. Depth of field is controlled by the lens aperture - and extends for a distance in front of and behind the point on which the le






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






7. 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.'






8. Digital single lens reflex camera






9. A form of image compression when saving the image that discards data from it. Saving a picture as a JPEG uses lossy compression.






10. The primary colors of light (not of the inks used in printing) are red - green and blue - known by the acronym RGB.






11. 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






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






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






14. (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






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






16. 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






17. 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.






18. 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'.






19. Exchangeable Image File Format. Data produced by a digital camera that becomes attached to each image made by the camera - including make & model of camera - date & time - image format (e.g. jpeg - tiff - etc.)and dimensions - color & exposure modes






20. 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.






21. Exchangeable Image File Format. Data produced by a digital camera that becomes attached to each image made by the camera - including make & model of camera - date & time - image format (e.g. jpeg - tiff - etc.)and dimensions - color & exposure modes






22. 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'






23. An image file type created in Adobe PhotoShop. It is uncompressed and contains data on editing that is done to the image. A PSD file is essentially PhotoShop's version of a TIFF file. It lets you save a picture you are working on with its layers - ch






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






25. 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.')






26. 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.






27. 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






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






29. 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.')






30. Digital single lens reflex camera






31. 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






32. 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.






33. Also known as the 'Kodak neutral test card -' a gray card is an 8' X 10' (20 cm by 25.5 cm) card - about 1/8' thick - that is uniformly gray on one side. The gray side reflects precisely 18% of the white light that strikes it (corresponding to the ca






34. 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






35. 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'






36. Bokeh describes the rendition of out-of-focus points of light. Bokeh is different from sharpness. Sharpness is what happens at the point of best focus. Bokeh is what happens away from the point of best focus. Bokeh describes the appearance - or 'feel






37. A function or shooting mode of a semi-automatic camera that permits the photographer to preset the aperture and leaves the camera to automatically determine the correct shutter speed. What does that mean? You select the aperture setting you want and






38. A form of image compression when saving the image that discards data from it. Saving a picture as a JPEG uses lossy compression.






39. Tagged Image File Format - A standard digital image format for bitmapped graphics in an uncompressed state. The image files are much larger than compressed files - but can be opened in all image-processing programs.






40. 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.






41. The primary colors of light (not of the inks used in printing) are red - green and blue - known by the acronym RGB.






42. 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






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






44. 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






45. 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.






46. 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.
