1992

The _Prosumer_ category of digital cameras is where it all comes together; affordable price, the size of the camera, interchangeable lenses and picture quality.

false, DSLR (digital single-lens reflex)

A big advantage of digital photography is the instant feedback a photographer gets by being able to view a photo immediately after pushing the shutter button.

true

The resolution of which device is expressed in dpi?

the printer

How many colors or tones is a camera capable of recording if it is working in a bit depth of 8?

256

When printing a photo with a modern ink-jet printer, the most bit depth possible is 8-bit.

true

Which color mode is best to use for images that will end up on an internet web-site?

Adobe RGB

Which file format is best to shoot in if you want to record all the information that your camera's sensor sees?

RAW

Which type of computer storage format compresses information every time you save it?

JPEG

The less resolution an image contains; the better the quality of the final photo.

false

What is the ideal file format in which to save a photo that has been edited in PhotoShop in order to preserve all of it's various adjustment layers?

PSD

A number that describes how much magnification of the subject that a lens will employ is called?

focal length number

Digital zoom lenses are _superior_ in their image quality to their optical zoom counterparts.

false

In the most basic sense, each pixel on a camera's sensor _cannot_ "see" colors just brightness levels.

true

The length of time that passes between pressing the shutter button and when the shutter is actually opened is called?

shutter lag time

Noise in a digital photograph is caused by what thing(s)?

cranking up the ISO number & heat building up in the sensor because of long exposure times

When a digital camera's processor uses data from surrounding pixels to determine brightness values for two other colors, this is called _buffering_.

false, interpolation

The speed at which a camera can write information to a memory card is called?

writing speed

A photographer should always use the _highest_ ISO number possible in a given lighting condition in order to get the clearest, best possible results with the least amount of noise.

false, lowest

What is the grid of red, green and blue filters called that is placed over your digital camera's sensor in order to record a scene in full color instead of just black and white?

the Bayer pattern

Mr. Isaacson said to choose a memory card for your camera that is neither too small to be constantly worrying about how many shots you have left, nor too big to be cost prohibitive and have too many eggs in the same basket. Of the following choices, which sized card would make the most sense?

8 Gb

According to your textbook, which type of camera sensor is most prevalently used in DSLRs today?

CMOS

Which type of tripod head is the easiest and quickest one to adjust?

ball head

Zoom lenses are superior in their optical quality to fixed focal length or "prime" lenses.

false

Your camera's built-in or pop-up flash unit is not very powerful and can only illuminate subjects that are less than 20 feet from the camera.

true

Which one(s) of the following filters blocks ultra-violet light from entering the camera and also protects the front of your lens from physical damage?

skylight, haze, UV

Which filter listed below eliminates reflections and saturates colors in a scene?

polarizer filter

Mr. Isaacson said that the single greatest filter you could ever purchase and use in your photography would be a _graduated_neutral_density_ filter because Photoshop cannot duplicate this filter in post production.

false, polarizer filter

Which of the following tools can assist the photographer in getting a more accurate exposure for their picture if they remember to use it?

18% gray card

Which of the following lens apertures would allow the least amount of light into the camera?

highest

Which of the following ISO values would give the greatest amount of noise in your photos?

highest

Which of the following camera shutter speeds would be _best_ to use if you were trying to _freeze_ the motion of a basketball player going up for a slam dunk?

lowest

Which filter listed below would a photographer use to reduce the amount of light entering the camera in order to use a super-long shutter speed during a daytime picture?

neutral density filter

Which in camera file format takes up about the same amount of memory as the number of megapixels used by the camera's sensor?

RAW

When trying to determine what ISO to use, refer to the rule that states that you should use the _highest_ ISO you can, to achieve the best quality image you can.

false, lowest

Mr. Isaacson said to set your camera's built-in white balance function to the auto mode.

true

Which of the following in-camera white balance options would give you the _most_accurate_ results?

custom—take a photo of a white or gray card

Which camera exposure mode is the camera in when you set the aperture and the camera sets the shutter speed?

aperture priority mode (A or Av)

Always remember to reformat your camera's memory card in your _computer_ before reinstalling it back in the camera.

false, camera

The exposure latitude or dynamic range of a digital capture is most closely similar to that of?

color slide film

About how many f-stops or brightness levels is an older model, entry-level camera capable of recording?

5

The smaller a camera's sensor is, the harder it will be to obtain _small_ depth of field.

true

If you averaged out all the tones in a normal photographic scene the sum total would be?

18% gray

An _incident_ light meter provides a _more_ accurate exposure reading than does a _reflective_ meter.

true

Most cameras contain a _reflective_ light meter.

true

Which of the following is not a problem situation for most camera meters?

backlit subject

snow or beach scenes

nighttime cityscapes

none of the above

Which item or items listed below is/are acceptable as "blown out" highlights in a digital photo?

both sources of direct light and specular highlights

If you are in doubt about the exposure of a scene, it is best to _overexpose_ it just a little.

false, underexpose

In which zone of the histogram is most (1/2) of the pixel information contained?

within the fifth f-stop / lightest tones

Which action listed below would not help you overcome an impossibly high-contrast photo situation?

take a meter reading and add 3 f-stops to the exposure

The _best_ way to evaluate a picture for focus and sharpness is by viewing the image on your camera's LCD screen at _fit-in-screen_ mode.

false

If a photo looked too dark on the LCD screen of your camera, dialing in a plus-one on the exposure compensation system and retaking it would lighten it up.

true

Which camera metering mode is the _best_ one to use most of the time?

matrix/multi-segment

Describe the "average" scene photographically that your camera's light meter is based upon. Give both an indoor and an outdoor example.
