  1. Digital Cameras • District Choices • SLR vs. Fixed Lens • Photo editing with Gimp

  2. Nikon Digital SLR D50 & D40 Canon PowerShot A460 Cameras of Choice for the District Kodak EasyShare C330

  3. SLR means "Single Lens Reflex" This means that when you look through the viewfinder of the camera, you are looking through the same lens through which light will pass to the sensor.With an SLR, if the lens cap is on everything is dark. If your hand is covering half of the lens you see it. The biggest advantage of SLRs besides seeing exactly the same image that will expose the sensor is that SLRs have interchangeable lenses. You can remove lenses and replace them with wide-angle lenses for landscape shots and telephoto for sports or wildlife. They are great for action shots. Click on the camera for a great review of both kinds of cameras Fixed Lens = “Point and Click" With a fixed lens, there's a separate lens you're looking through, so you might actually have then lens cap on, or a finger over the lens and not realize it until you see the picture. These cameras are great for stills but not as good for action shots.

  4. The cameras our district has chosen use SD (Secure Digital) Memory Cards for storage. These are the same cards that go into many Palm products or Treo phones. They come in various sizes and prices. Better Cameras mean LargerFiles You want to take high resolution pictures but for web pages, e-mails, desktop publishing, and multimedia presentations you will need to resize your photos.
