  3. 3. 22 Sep 2009 Cosmic 2009 2 - Aims “ Subject Headings” <ul><li>Where did they come from…? </li></ul><ul><li>Using your camera </li></ul><ul><li>You’ve seen a camera…. </li></ul><ul><li>Taking a good picture </li></ul><ul><li>What to do with your photos afterwards </li></ul><ul><li>Photo shoot </li></ul><ul><li>Picasa </li></ul>
  4. 4. <ul><li>Where did they come from and what is going on? </li></ul>22 Sep 2009 Cosmic 2009 slides
  5. 5. 22 Sep 2009 Cosmic 2009 1/4 <ul><li>“ ...did you know?” </li></ul><ul><li>It all started with NASA </li></ul><ul><li>One of the uses of these satellites was to spy on the enemy – 1959-1972 </li></ul><ul><li>Beaming photographs back to Earth, using ‘Digital Technology’. </li></ul><ul><li>The ‘Charge-Coupled-Device’, (or CCD) was first demonstrated by Bell Laboratories in 1969 </li></ul><ul><li>The first images created with CCDs were only 100 x 100 pixels – not very clear </li></ul><ul><li>The next goal was to create a better picture, which they successfully did in 1978 with a pixel array of 500 x 500 </li></ul><ul><li>Soon after they’d developed 800 x 800 pixels, with a progression towards the development in 1982 of 1024 x 1024 pixels. The results were always a better picture, at a more affordable price </li></ul>Pixels
  6. 6. “ How it Works” (Charge Coupled Device) <ul><li>When a photo is taken, the CCD is struck by light coming through the camera's lens. </li></ul><ul><li>Each pixel (or tiny ‘dot’ on the CCD’s surface) converts this light into electrons. </li></ul><ul><li>The number of electrons, usually described as the pixel's ‘accumulated charge’ is measured, then converted to a digital value. </li></ul><ul><li>This conversion being undertaken by something called an ‘Analog-to-Digital Converter’ </li></ul>22 Sep 2009 Cosmic 2009 2/4 Back
  7. 7. “… Pixels” – ‘Mega’ or otherwise 22 Sep 2009 Cosmic 2009 3/4 Here is very simple pictorial representation of a ‘CCD’ in action. This ‘CCD’ has a resolution of (12 x 12) 144 pixels. Each dot that makes up the man is 1 ‘Pixel’. Because the ‘ resolution’ is so low the image has very limited detail. Back
  8. 8. “ Come the Resolution Comrade!” 22 Sep 2009 Cosmic 2009 4/4 – Using camera <ul><li>The image resolution tells us how many of those pixels an image contains </li></ul><ul><li>Your camera might have a setting which will allow you to change the final photos physical size </li></ul><ul><li>You should also have a setting to change the final photos resolution </li></ul><ul><li>To print out a photo to a decent quality or to a large size a high resolution is required. This will make the file size of the image larger </li></ul><ul><li>If you start off with a high resolution picture it is easy to remove pixels (ie lessen the resolution) </li></ul><ul><li>If you start off with a low resolution picture it is harder (near impossible) to add more pixels and keep the quality high </li></ul><ul><li>Related topics: Memory size, how many pictures do you want to take? </li></ul>
  9. 9. Using Your Camera 22 Sep 2009 Cosmic 2009 3 slides
  10. 10. “… Take Control!” Learn those settings 22 Sep 2009 Cosmic 2009 1/3 Video. Digital cameras can capture video. Get a large storage card (2 or 4GB’s) to give you enough recording time. Macro/Close-Up. This mode is used for taking close-up pictures. Night Time. Sets longer exposures to capture darker scenes. Usually used with flash, and some nice motion effects can be created. Portrait. To attempt to blur out the background the camera will try to use the fastest available lens setting (aperture). Landscape. The camera will attempt to capture detail in foreground and background by using high f-stop (aperture) settings. Sports. To freeze motion the camera will use the highest shutter speed possible. Stitch. For creating multi-shot panoramas. This mode will help to combine several shots into one wide scene.
  11. 11. “… Zooooooooom!” Optical V Digital <ul><li>Optical zoom lenses actually “move” you closer to the subject of the photograph without sacrificing quality. </li></ul><ul><li>The higher the optical zoom rating on a camera, the farther away you can be to take a photograph and still get a clear, close-up image. </li></ul><ul><li>The concept of optical zoom essentially the same as the zoom on a film camera. </li></ul><ul><li>Optical zoom is the number you want to pay close attention to--it’s the zoom that will give you the quality results you want. </li></ul><ul><li>Digital zoom on the other hand is not bringing you closer to the item. </li></ul><ul><li>The camera crops the entire image, and then digitally enlarges to the size of the viewfinder the portion you want to zoom in on. </li></ul><ul><li>This results in a loss of quality, and is no different than cropping and enlarging an image with editing software. </li></ul><ul><li>When you use digital zoom on the camera, the image quality is irreversibly lost. </li></ul>22 Sep 2009 Cosmic 2009 2/3
  12. 12. The Internal Menu 22 Sep 2009 Cosmic 2009 3/3 - Coffee The cameras internal menu gives you access to many important adjustments… … Image size & resolution, WB, ISO, and creative settings
  13. 13. <ul><li>Coffee? </li></ul>22 Sep 2009 Cosmic 2009 11:30 ish - You’ve seen…

  15. 15. 22 Sep 2009 Cosmic 2009 1/4 Which Camera would I buy? … what to consider <ul><li>Its cost! </li></ul><ul><li>The number of ‘Mega-Pixels’ </li></ul><ul><li>Its lens </li></ul><ul><li>Optical Zoom figure </li></ul><ul><li>The features </li></ul><ul><li>View finder or not </li></ul><ul><li>Have you picked it up? </li></ul><ul><li>Is it easy to use? </li></ul>
  16. 16. Storage media? 22 Sep 2009 Cosmic 2009 2/4 2 on Memory cards Memory cards. Your camera probably came with a memory card. What’s a memory card? When you take a photo with a digital camera, most cameras store the images on a memory card. N.B. The 32MB card they supply with the camera when you first buy it isn’t going to let you store very many pictures at all! … throw it into your camera bag and forget it!!
  17. 17. “… don’t forget extra memory!” 22 Sep 2009 Cosmic 2009 3/4 Modern memory cards come in different formats, ‘SD’ and ‘CF’ cards being the most popular in sizes of up to 64GB! 1 gigabyte = 1,000,000,000 bytes (or one billion bits of information) Consider: Speed as well as size!
  18. 18. “… Batteries, so?” 22 Sep 2009 Cosmic 2009 4/4 - Taking a good picture <ul><li>Batteries? </li></ul><ul><li>How many? </li></ul><ul><li>Which type? </li></ul><ul><li>What sort of charger? </li></ul><ul><li>How many to take with me? </li></ul><ul><li>How much life have you left in your current batteries? </li></ul>

  21. 21. 22 Sep 2009 Cosmic 2009 2/2 – What to do “ TIP-TOP TOP-TIPS!” … Know your camera? Experiment with it - have a play! ‘ A’ for Auto The ‘Auto’ function is designed to calculate the average everything. Learn all about your own camera! Be adventurous! Use your Manual setting or creative settings Set your camera up for the day before you go out! Try not to use a flash, use natural light Don’t forget to order a new, larger storage card Learn how to review/delete your image Always have your camera take the largest images possible Be wary of buying low cost digital cameras Think before you zoom! Frame your image - think about leading the eye Avoid printing out your pictures on plain paper!
