1. Digital Camera Overview IT 130 Web Graphics and Multimedia

2. Digital Camera Overview Images are recorded on CCD (Charged Coupled Device) ; not film Light collected by CCD converted to data Data stored on camera’s memory card

3. Digital Camera Overview Image preview capabilities Image downloaded to a computer

4. Digital Camera Advantages Reusable Instant preview of image After download, image may be edited

5. Digital Camera Advantages Image sent via e-mail or posted to websites without compromising quality Reduced film and development costs

6. Digital Camera Overview

7. Image Compression Quality and file size are affected Reduces memory required per image Uncompressed image – 10MB Standard card size 8-16 MB

8. Image Compression Compression levels can be adjusted on the camera or after downloaded Image cannot be uncompressed JPEG most common compression format

9. Image Compression

10. Low compressionFile Size 68KB

11. Image Compression High compressionFile Size 11KB

12. Image Compression Smaller file sizes desired for Internet TIFF format better at compression with minimal quality effects

13. Image Resolution Quality and file size also affected Directly related # of pixels on CCD More pixels, higher the resolution

14. Image Resolution

17. Pixels Smallest piece of info on digital image 800 x 600 resolution = 480,000 pixels 1024 x 768 resolution = 786,432 pixels

18. Pixels Most current cameras – 2048 x 1532 Over 3 million pixels (3 Mega Pixels)

19. Pixels Camera’s CCD is made up of pixels Each pixel is a tiny light sensor – detects light & color levels

20. Pixels Example: 12 x 12 resolution = 144 pixels Low resolution = limited detail

21. Camera-Computer Transfer Serial port or USB port Serial port uncommon and slow USB faster, but newer technology

22. Camera-Computer Transfer Some cameras use a standard 3.5 disk Many new digital cameras USB support only Another option is memory card with memory card reader

23. Camera-Computer Transfer

24. Storing, Viewing & Printing Storage requirements often neglected Hard drive failures CD burner possible alternative

25. Storing, Viewing & Printing Photo Album Software Digital Photo Frame - Ceiva

26. Storing, Viewing & Printing Online – shutterfly.com TV – low quality

27. Storing, Viewing & Printing Printing – Shutterfly.com and Ofoto.com Personal printer

28. Storage Media Removable memory card Smart Media Compact Flash (Type I & II) Stick memory 3.5 disk – 1.44 MB vs. 8-16 MB memory card 128+ MB memory cards available
