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. 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






2. Digital single lens reflex camera






3. 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.






4. 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






5. 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






6. 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.






7. 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.')






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






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






10. 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






11. 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.






12. 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

16. 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






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






18. 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






19. 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.






20. 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






21. 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






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






23. Occurs when saving a digital image file in a format that does not result in a loss of data. A TIFF and PSD documents are examples of lossless image formats






24. 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.






25. 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






26. 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

31. 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.






32. 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'.






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. 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 -






35. 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

37. 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.






38. 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






39. 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.'






40. When the lens is focused on infinity - the nearest point to the camera that is considered acceptably sharp is the Hyperfocal point. By focusing on the hyperfocal point - everything beyond it to infinity remains in acceptable focus - and objects halfw






41. 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.






42. 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.

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






45. 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.






46. 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'.
