Storage Media
• SD card
• Memory stick
• Compact flash card
• Internal memory
![Page 7: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/7.jpg)
Memory Cards vs. Internal Memory
• SD cards, memory sticks, and Compact Flash cards - removable storage devices.
• Internal memory – built in storageInternal 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.

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

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.

Optical Zoom
• Zoom that physically increases the length of the lens, essentially creating a magnifying glass; produces a higher quality lens.
![Page 12: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/12.jpg)
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
![Page 13: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/13.jpg)
Flash

![Page 17: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/17.jpg)
Composite Techniques
• Rule of thirds• Point of view• Frame movement
![Page 18: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/18.jpg)
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
![Page 19: Unit 2: Photography Digital Communications II. Digital SLR and Point and Shoot Cameras](https://reader036.vdocuments.net/reader036/viewer/2022062320/56649d005503460f949d2f6a/html5/thumbnails/19.jpg)
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

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.

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