Digital Cameras Dec 2008 Ppt 2007 Slideshare Digital Cameras Dec 2008 Ppt 2007 Slideshare Presentation Transcript

  • “ Jelly Beans, Pictures & Portraits” Created Nov 2006 – Updated Dec 2008
    • Pixels = Dots
    Jelly Beans Pixels
  • Jelly Beans View slide
  • Pixels View slide
    • This photo measures
      • 640 pixels wide
      • 480 pixels wide
    640 x 480 = 307200 pixels
    • The larger you make a picture, the more you will see the pixels.
    • The higher the megapixel, the better the photograph
    • But, how big a picture will you ever print?
    • 110 cameras vs 35mm cameras?
  •  
  •  
    • 2,880,000 pixels = 2.8 Mega Pixels
    1800 x 1600 = 2,880,000 1800 pixels 1600 pixels
    • Easy to share with others
    • You see them immediately
    • Saves you $ by not having to buy film
    • View images before they’re printed, edit them or delete them
    • Print them right away
    • No loss of image quality if stored properly
    • Lens
      • Brings light from the scene into focus inside the camera
    • Aperture
      • Hole that can be made smaller or larger to control the amount of light entering the camera
    • Shutter
      • Device that can be opened or closed to control the length of time light enters the camera
    • The lens plays a very  important roll in the quality of photos you take with any digital camera.
    • You can buy a 6 megapixel camera, but if it has a cheaply made lens on it, the images may not even contain as much detail as a high quality 3 megapixel camera from a major brand.
    • Some cheaper models of cameras have plastic or poor grades of  glass for a lens, so when you're browsing Ebay and see these no-name cameras, beware - you're not getting a top quality lens on them.
    • Other more expensive models have coated, multi-level glass lenses.  While pixels and the quality of the image sensor play rolls in how well your photos will turn out, neither does the job on it's own.
    • The lens must be a high quality lens in order for you to take good photos.  Canon, Nikon, Fuji, Sony, and Olympus are popular for their high quality of lenses on their digital cameras.  In case you're wondering just HOW much difference inferior lenses can make to a digital image... look at the image below of the bricks.
  •  
    • Point and Shoot
    Fully Automatic Point and Shoot Cameras 5 to 9 megapixels $100 to $350
  • Compact 7 to 12 megapixels $200 to $500
    • Extended Zoom
    More Advanced Features Focusing Through the Viewfinder Control Lighting 6 to 12 megapixels $300 to $600
    • Digital SLR
    For the Serious Photographer Interchangeable Lenses 6 to 10 megapixels $850 to $2000
    • Match the size to your needs …
    • They all take decent pictures
    • Is camera size important to you?
    • Do you want more “photographic” power?
    • 5 megapixels : minimal resolution
    • 8+ megapixels : overkill?
    • Zoom : 3x to 12x
    • More megapixels = more picture detail
    • Beyond 5 megapixels, you’re unlikely to see the difference unless you
      • Crop heavily
      • Make poster-size prints
    • High resolution does NOT assure high overall print quality, since other factors, such as lens quality , affect the picture
  •  
    • In this sample image below, you can see full sized sections of a photo of a car and tree.  On the left is as it appears with NO digital zoom.  The middle section is at about a 3X digital zoom, and the right section is the digital zoom at 5X.  You can see how severely digital zoom degrades an image quality as you use it.
  •  
    • Compact cameras are less expensive
    • Subcompacts cost more, but worth it if you want to carry it in your pocket
    • Prosumer cameras if you want lots of control over exposure and the image but prefer a built-in lens
    • Go for a super-zoom if you want to shoot close-ups of distant subjects
    • SLR if you must have it all and can afford separate lenses
    • Compact Cameras
      • Canon PowerShot A650 IS $400
      • Canon PowerShot G9 $550
      • Canon PowerShot A590 IS $170

    • What replaces FILM?
      • Media cards
        • SD cards : Secure Digital
        • SmartMedia Cards
        • XD cards
        • Sony Memory Sticks
        • CompactFlash
    • CDs & DVDs
    • Web Hosts
    • Flash Memory
  •  
    • Use NiMH batteries (Nickel-Metal Hydride)
      • They perform better than alkalines…
        • BUT
        • They discharge when not in use
        • SO
        • Always keep disposable alkalines as a backup
    • The higher the mAh the better
    • 2500 mAh
    • mAh stands for Milliamp Hour , a technical term for how much power a particular battery will hold. Digital camera batteries with higher mAh values theoretically last longer without requiring a recharge , allowing you to take more photographs before you have to replace your batteries. It is recommended when placing batteries in a digital camera that their mAh values match . Otherwise, it is possible that one lesser mAh battery will drain before the others, causing extra strain on the remaining batteries or causing your digital camera to not work until all batteries are replaced .
