1. Digital Photography and photo manipulation Richard Hine

2. Digital photography and image manipulation I can Appreciate the differences between digital and optical cameras and the advantages of the digital photography process Take digital photographs Understand the use and limitations of the flash (useful distance, red eye reduction etc) Understand image size / quality Transfer images from a camera to the computer either through cable or a digital card reader Appreciate the differences between bitmap and vector graphics and their uses and limitations Recognise common bitmap formats Understand the use of common paint tools, paintbrush, aerosol, eraser, clone brush and selection tools. Select appropriate image resolution for printed and computer output. Understand memory verses image quality issues. Crop images Resize images Change image quality depending on use. Including memory verses image quality issues. Be able to save images in different formats to preserve quality or save memory Remove scratches / red eye or use sharpen / blur (on selected areas and whole image) Understand how to adjust the transparency of a layer Understand how to alter colour values (hue, saturation, lightness) Adjust contrast and or brightness to improve on screen and printed appearance Appreciate the differences in paper types for producing digital photograph output

3. Optical Camera

4. How does an optical camera work

5. How does an optical camera focus

6. Out of focus?

7. Aperture

8. Changing the aperture

9. Digital cameras

10. Using the flash The flash illuminates an object The light bounces back off the object The reflected light enters the camera Until the shutter closes

11. Using the flash The background is dark because the light did not have enough time to reflect back to the camera before the shutter closed. If the shutter is held open longer (manual mode only) more of the background will become visible. The foreground can become too light though.

12. Red Eye This happens when the flash is used. Light is reflected by the retina (the back of the eye) The retina is red (lots of blood vessels!!)

13. Red Eye

14. This has used very basic digital manipulation, but it is very difficult to do well, notice the dog.

15. Red Eye Cameras use multiple flashes to close the iris before the picture is taken This reduces reflection from the retina This should eliminate red eye.

16. Depth of field Large aperture, cards out of focus Small aperture, most cards in focus, greater depth of field

17. Framing a photo Framing a photo can be the difference between a great photo and a rubbish one. Where is the point of interest? What will the viewers eyes do? What can you do about it?

18. Dead centre Object centre Just a snapshot

19. Rule of thirds

21. Eye movement

22. Framing This picture shows the frames only as an idea

23. Framing

24. Important There is no right and wrong!!!!!! You decide what works Why always take photos standing up at eye level? Try to vary things.
