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. Digital single lens reflex camera






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






3. 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'.






4. 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






5. 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






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






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






8. 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






9. 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






10. A lighting technique that is sometimes used in studio portrait photography. It can be achieved using one light and a reflector - or two lights - and is popular because it is capable of producing images which appear both natural and compelling with a






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






12. 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.






13. 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.






14. 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.')






15. 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






16. 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






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






18. 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






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






20. 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






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






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






23. 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.






24. 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.






25. 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






26. 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






27. 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.'






28. 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'.






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






30. 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'.






31. 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.






32. 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






33. 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






34. 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






35. 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






36. 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.






37. Sometimes called camera raw - raw format - raw image format and raw. A digital image storage format that contains the most information possible from a camera's sensor. RAW data ( a RAW image file) is unprocessed. Some folks consider it to be the digi






38. 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






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.


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. 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.






42. 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






43. 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






44. 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.






45. 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 -






46. 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'






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