  1. Name two ways you can increase depth of field (other than changing aperture)
  2. incident light
  3. noise reduction
  4. Command + R
  5. Command + Option + 5
  1. a 1) Use a shorter focal length; 2) Move farther away from the subject
  2. b Show in Explorer / Finder (Library and Develop module only)
  3. c A technology used to cut down on the amount of random information in a digital picture, usually caused by long exposures at increased sensitivity ratings. Noise reduction is automatically applied for long exposures, and it involves the camera automatically taking a second blank/dark exposure at the same settings that contain only noise, and then using the blank photo's information to cancel out the noise in the original picture. Although the process is very quick, it does double the amount of time required to take the photo.
  4. d Light falling on a surface.
  5. e Go to Web module

5 Multiple choice questions

  1. Select flagged photos
  2. A term derived from the Japanese word for blur, which describes the aesthetic qualities of the out-of-focus parts of an image. Some lenses produce "good" bokeh and others offer "bad" bokeh. Some lenses produce uniformly illuminated out-of-focus discs. Others produce a disc that has a bright edge and a dark center, producing a "doughnut" effect, which is the worst from a bokeh standpoint. Lenses that generate a bright center that fades to a darker edge are favored, because their bokeh allows the circle of confusion to blend more smoothly with the surroundings. The bokeh characteristics of a lens are most important when you're using selective focus (say, when shooting a portrait) to deemphasize the background, or when shallow depth of field is given because you're working with a macro lens, with a long telephoto, or with a wide-open aperture.
  3. Click with the neutral-point dropper on the selected color
  4. An accessory flash unit that supplements the main flash, usually triggered electronically when the slave senses the light output by the main unit, or through radio waves.
  5. A type of lens distortion in which lines at the top and side edges of an image are bent inward, producing an effect that looks like a pincushion.

5 True/False questions

  1. lossless compressionAn image-compression scheme, such as TIFF, that preserves all image detail. When the image is decompressed, it is identical to the original version.

          

  2. The quantity of light that reaches your sensor is controlled by what?Aperture

          

  3. What is a flag?The smallest unit of information consisting of either a 1 or a zero. It can only represent two possibilities - either yes or no, black or white.

          

  4. Cyan is composed of equal parts of what two colors?Blue & Green

          

  5. What is the inverse square law?The size of the opening in the lens which controls the amount of light reaching the sensor.
