1. Digital Cameras An Introduction to Digital Cameras and the Basic Parts of a Canon A85

2. One of the 1 st Digital Cameras This was a digital back created for a popular Nikon Film camera. In 1994, the camera cost about $12,000! It was a 1.5mp (1524x1012 pixels)

3. Kodak DCS 620 One of the first 2mp cameras. $10,495

4. Kodak DCS 760 One of the first 6mp cameras. July 2000…$25,000. By July 2001, street price dropped to $8,000 to compete with Nikon’s own camera, a D1, and a Canon model, the D30.

5. Canon A85 Many Canon models are very similar to you class camera. Other manufactures will also be similar.

10. Not all Camera CCDs are created Equal… A85 APC Sensor

11. Exposure Mode Controls Auto (point & shoot) Program Shutter priority Aperture priority Manual setting

12. Auto Mode: When you want to take snapshots without worrying about the mechanics of photography, put the camera on Auto. This mode sets all exposure levels automatically, and it usually locks you out of making any minor adjustments manually. This is for general picture taking.

13. SCN: Exposure and White Balance is selected to match the picture you are taking.

14. Flash Modes You will not have control over the flash in all modes on your camera. In Auto, the camera usually will only allow AUTO FLASH (the camera decides when to flash) or FLASH OFF (no flash at all). One of the best flash modes is FLASH ON…which will allow your camera to flash even if it doesn’t think it needs it. If you subject is close, it will fill in shadows, etc.

15. Resolution Setting Resolution and Compression determine the total image quality. Some cameras may not allow you to change the compression. Always shoot at the highest resolution…you can always make it smaller.

17. Memory Cards: Each camera comes with a memory card or built- in memory. You can buy larger memory cards to hold more pictures.

18. Memory Cards We use Compact Flash…and a card reader to transfer images.

22. ISO Selection Ability to vary “film speed” for lighting conditions ISO 50 ISO 400 Canon G1is first digital to offer ISO 50

23. Understanding ISO Just because your camera CAN shoot at HIGH ISO, doesn’t mean you should. Generally, try to stay one stop lower than the maximum ISO. Example: If your camera’s max ISO is 800…don’t go above 400. Don’t use Auto ISO. Nikon D200 ISO 1600Nikon D300 ISO 1600

24. EXTREME High ISO

25. Nikon D3 was first to offer the insanely high ISO 25,000

32. 6 th Century Italian Mosaics

33. 19 th C. French Neo-impressionist painting The Pointillist Artist Image consists of small dots of paint Dots (pixels) made with point of brush as small as 1/16 inch Dots are unequal in size

35. Textile example – hand made stitchery

36. Image Printing Screen Photo screen can be course or fine Need black ink for single color Dots not equal size Eye reads dots as continuous tone image
