10. Digital Camera Digital cameras work in the same way that a film camera works. The difference between the two is what you find inside.

12. Digital Camera Step 1. Point to the image to photograph and take picture. Light passes into the lens of the camera How it works

13. Lens Construction The quality of a lense is determined by the manufacture and the construction In the diagram at the right the lens has 6 elements in 4 groups Another feature of any lens is it’s aperture, the size of the opening that allows light through

14. Lens Construction The aperture of a lens is measured in f-stops The smaller the f-stop number the more light is admitted F-stop measurement is based on lens diameter and focal length

15. Digital Camera Step 2. Image is focused on a chip called a charge-coupled device (CCD).

16. This is what a CCD looks like

17. Digital Camera Step 3. CCD generates an analog signal that represents the image

18. Digital Camera Step 4. The Digital Signal Processor (DSP) converted the analog information to digital information, enhances it and prepares it for output. DSP

19. Digital Camera Step 6. The formatted digital image is stored on miniature mobile storage media in the camera. DSP

20. Memory Card Types Secure Data (SD) MultiMedia (MM) Compact Flash Smart Media (SM) xD Picture Card (xD) Memory Stick (MS)

21. Camera Resolution Factors that effect resolution;  Shutter speed  Camera motion  Subject motion  Lighting/contrast  Focus  Optics  Megapixels
