Depth of field: -describes how much of the image is in sharp focus (subjects in foregrounds are clearer than subjects in background)

Shutter Speed: -the amount of time the shutter is open (how much light is let into the lens)

Noise: -apparent by the presence of color speckles where there should be none



Histogram: -a quick summary of range of tones in any image

Burst Mode: -mode where many pictures are taken in one press of the button

White Balance: -getting the closest to the colors in your image as they are in real life

Self timer: -A self timer is a device on a camera that allows someone to set a time length, run over into the line of sight, and then the camera will go off and snap the photo. In simple terms it’s a device that allows the camera to take a picture by itself.

Pixels: -In digital imaging, a pixel (or picture element) is the smallest item of information in an image.

Auto Focus vs Manual Focus: (explain what they are and then explain when you would choose each and why?) -Auto Focus allows the camera to zoom and focus for you so you don’t have too. It picks the best setting that it thinks will work. This is helpful if you don’t feel like thinking or can’t tell what’s best. -Manual Focus allows you to change the zoom and focus to best suite your needs. This is helpful if the camera can not pick up on the image you are trying to shoot.

ISO (international standardization organization): -ISO is a number rating that indicates a digital camera’s sensors sensitivity to light. The higher the ISO number the less light needed; however, a lower ISO setting on your camera usually means less noise in the photo.



File Format: Define each and explain how they differ from each other. .tiff – tagged image file format, TIFF doesn't utilize any sort of lossy compression, meaning the format still maintains the full information of each image. As a result, TIFFs don't suffer from any sort of artifacting, nor are they small in any sense of the word.



.jpeg – Joint Photographic Experts Group, are among the most highly used formats for compression, and are the essential standard for non-transparent photographs and images on the web.



.raw – Rather than simply capture the data from the image sensor, then write it to memory as a file format, RAW files instead save all the metadata associated with an image, and bundle it with the raw data (hence the name) from the sensor.



Differences- Both RAW and TIFF formats do not apply any compression to the photo to save space on your memory card. When your camera saves a digital photo as a RAW or TIFF file (if it can), the photo includes all of the information captured by your camera's image sensor. JPEG is a far more common file format, and it does use compression. It is a much more popular format with the consumer market because it allows a 128 MB media card to store a ton of photographs
