Unit 2: Photography Digital Communications II

2 Digital SLR and Point and Shoot Cameras

3 SLR Cameras Detachable lens for different distances
Broader range of manual settings Large ISO settings Aperture Manual zoom Expensive Bulky

4 Point and Shoot Cameras
Easy to use Automatic Limited manual settings Compact Lightweight Non-expensive

5 Components of a Digital Camera
Storage media Battery Optical zoom Digital zoom Flash Preview mode Mode dial LCD screens

6 Storage Media SD card Memory stick Compact flash card Internal memory

7 Memory Cards vs. Internal Memory
SD cards, memory sticks, and Compact Flash cards - removable storage devices. Internal memory – built in storage Internal memory space is limited. To remove the images from the internal storage a cable is required. Memory cards can be filled, removed and replaced with another memory card. Card readers enable you to move the pictures from the memory card to the computer.

8 Transferring Digital Images
USB cables – used to transfer images from a camera to a computer Bluetooth – wireless transfer of images Card readers – input device that reads memory cards

9 Battery SLR cameras require a battery that will need to be recharged after hours of use A point and shoot camera requires lithium batteries, typically AA. Rechargeable batteries and a battery charger can be purchased.

10 Battery, cont. SLR Camera Point and Shoot

11 Optical Zoom Zoom that physically increases the length of the lens, essentially creating a magnifying glass; produces a higher quality lens.

12 Digital Zoom Zoom takes a portion of the image and enlarges it electronically; the image quality is reduced since digital zoom enlarges the same set of pixels without adding detail

13 Flash A device used in photography producing a flash of artificial light

14 Preview Mode Used to review images taken

15 Mode Dial Used to change camera functions

16 LCD Screens Allows user to see what the image will look like

17 Composite Techniques Rule of thirds Point of view Frame movement

18 Rule of Thirds Arrangements of elements in a picture
Image is broken down into 9 equal parts Points of interest should occur at 1/3 or 2/3 Creates strong focal points

19 Point of View Position, direction, and height of a camera
Change the way your subject is perceived by changing the camera position Make actor look taller Change the mood of a photo

20 Point of View, cont.

21 Frame Movement A frame is an image frozen in the process of movement and represents the object's position at a specific point in time.

22 Framing Where the foreground frames what is being photographed in the background

23 Into the Frame The subject typically should be moving toward or facing the center of the photo

24 Basic Framing Shots Long shot Mid shot Close-up Extreme close-up

25 Long Shot A framing technique used to capture the environment and full body of subject

26 Mid Shot A framing technique that captures the subject from the waist up

27 Close-up Framing technique that captures the head and shoulders of the subject

28 Extreme close-up A framing technique that cuts off top of head and chin of subject

29 Camera Resolution The quality or sharpness of an image, usually measured in pixels per inch; the more pixels, the higher the resolution

30 Megapixels One million pixels; describes the size of the images captured by a camera

Organization Folders Event Date Name or date pictures
