Photography Basics

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






2. 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






3. 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






4. 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'.






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






6. 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






7. 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.






8. 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






9. 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






10. 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.






11. 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






12. 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.






13. 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






14. 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






15. 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 -






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






18. 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






19. 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.






20. 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






21. 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






22. 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






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






24. Digital single lens reflex camera






25. 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






26. 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






27. 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






28. 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.

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






31. 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.

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






36. An image of a single color in differing shades. A black and white or sepia-toned image is a monochrome. Another monochromatic image is the cyanotype - or blue-green image made popular in blueprints.






37. 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.')

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