  • Right now there is a huge demand for pictures, drawings and images online, and a shortage of people supplying them.

    These pictures could be pictures of your pets, fruit, trees or anything you take with your camera. Companies will buy the rights to use your pictures online and are willing to pay you a lot to do it!

Digital Photograpy

  1. 1. Digital Photography Bethany Smith Learning Technologies
  2. 2. The Camera - Front
  3. 3. Shooting Modes • Auto • Portrait • Landscape • Running Portrait & Landscape shooting modes are not the same as orientation
  4. 4. The Camera - Back
  5. 5. Taking Pictures • Hold it steady • Use natural sunlight whenever possible • Put the sun behind you • Get close…almost too close • Use proportion • Use the horizon as a guide http://www.kodak.
  6. 6. Rule of Thirds Imaginary lines are drawn dividing the image into thirds both horizontally and vertically. You place important elements of your composition where these lines intersect. http://www.betterphoto .com/exploring/tips/thirds.asp
  7. 7. Rule of Thirds Example
  8. 8. Off Center…. but in a good way • Hand in hand with the rule of thirds is keeping your subject off center
  9. 9. Up-close & Personal
  10. 10. Up-close & Personal • Embracing your inner zoom & the MACRO feature on your camera • The macro mode button, when pressed, switches the camera into a special close focus mode and allows the photographer to shoot less than 10cm from the picture subject.
  11. 11. Macro
  12. 12. Go Vertical! • The camera is not locked in a horizontal position! • Vertical pictures suit some subjects better - and are much easier to add in PowerPoints!
  13. 13. Action Shots • Keep taking pictures - you have space!
  14. 14. To Flash or not to Flash • Use natural light whenever possible • Use flash sparingly • If unsure, take one with and one without and decide later!
  15. 15. Memory Cards • Memory cards store the actual data files of your photos • The bigger the memory card the more photos you can take • The faster the memory card the faster you can take pictures • The memory card type is not as important as the two above features
  16. 16. Photo Safari • Find the following in the FI • Mr. Friday • A flower • A person working • A pen • Something in the shape of a circle You have 20 minutes!
  17. 17. Importing
  18. 18. Turn camera on and place in PLAYBACK mode once it is connected to the computer
  19. 19. Photo Applications • Mac • iPhoto • PC • Irfanview • • Both • Adobe Photoshop • Macromedia Fireworks
  20. 20. Editing Pictures
  21. 21. What is a Mega Pixel? • What is a Pixel first… • A pixel (short for picture element, using the common abbreviation "pix" for "picture") is one of the many tiny dots that make up the representation of a picture in a computer's memory.
  22. 22. What is a Mega Pixel? • A unit equal to one million pixels. • The higher the resolution, the more pixels in an image and therefore the greater the image quality. • An image file that is 1 megapixel (MP) can make a photo realistic print of 5 x 7 inches; a 2 MP file can make an 8 x 10-inch print; a 3 MP file can make an 11 x 14-inch print.
  23. 23. To Crop or not to crop • There is always room to crop! • Use the rule of thirds • Keep original • Don’t be afraid to get in close
  24. 24. Resolution • The number of pixels per square inch on a computer-generated display; the greater the resolution, the better the picture. • For display on a screen, 72 pixels per inch both vertically and horizontally is the maximum. • For print work, a higher number will give better results, such as 300 dots per inch. • With higher resolution, more memory space will be used for the image.
  25. 25. What do MP & Resolution have to do with me? • To find the largest photo quality image you can print, simply divide each dimension by ppi (I.e. 300 or 72) • A 3.2 MP camera has a resolution of 2048 x 1536 • 2048/300=6.83 • 1536/300=5.12 This will make excellent 4x6, but don’t print 8x10
  26. 26. Resizing photos • By pixel • During Export • In program • Size for purpose
  27. 27. File Types • GIF - raster-based color graphics file format, often used on the World Wide Web to store graphics. This is the type best used for cartoon-like images. • JPEG - A graphic format that allows images to be viewed on the Web. It allows compression of memory, using less space and facilitating faster load time on a Web page. This is the type best used for photographs.
  28. 28. Web images • GIF Images- Graphics Interchange Format (GIF) images are the most common type of image found on the Web. GIF images are limited to 256 colors, which is the same number of colors most computer monitors can display. • JPEG Images- Joint Photographic Experts Group (JPEG) images are commonly found on the Web. JPEG images can have millions of colors and are often used for photographs and very complex images. • PNG Images- Portable Network Graphics (PNG) images are a newer type of image specifically designed for use on the Web. PNG images can have millions of colors will eventually replace GIF images.
