  2. Digital Photography? • Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens

  3. 1. Camera control

  4. 1. Camera control… continue

  5. 2. Image sensor Image sensors, whether they are CCD or CMOS, vary from camera to camera but they’re basically the same, and the megapixel count shouldn’t be a priority in the decision-making process when buying a camera. Why? Because the size of the sensor is actually more important that the number of megapixels.

  6. 3. Camera lens • If you are concerned about picture quality, you should invest in a digital SLR (DSLR) camera with interchangeable lenses. • Interchangeable lenses allow you to have much more control of your images, and to be far more creative than you can be with a point-and-shoot camera.

  7. 4. Camera modes Shooting mode dial: to choose the desired shooting mode.

  9. : Techniques

  10. RULE OF THIRD The Rule of Third is a guideline for composing images

  11. Compose shots so that points of interest align with am imaginary grid that divides the image into thirds vertically and horizontally

  12. Like this…….

  13. Which looks like….

  14. The Rule of Third is a guideline for composing images

  15. Think about what elements of the photo are most important and try position them at or near the lines and intersection of the grid

  16. When photographing moving objects, position them as normal, but also pay attention to direction they’re moving

  17. Like this…….

  18. As a general rule you should leave more space in front of them than behind, to show where they’re going

  19. Another photography principle is the use of lines to draw the viewer's eye. "Lines can be the shape of a path, a line of trees, a fence, or any feature in an image" (Telg, 2010a, p. 2).

  20. Different types of lines can be used to convey messages and add interest to a photograph. • Diagonal lines can suggest depth or action. Vertical lines can convey power, strength, or even growth. • Horizontal lines can convey stability or rest and can easily follow the rule of thirds.

  21. Diagonal lines can add depth and perspective to any agriculture-related photograph, such as this photo of row crops in a greenhouse. • When photographing livestock in their natural environment, it is important that the environment be perceived as healthy and desirable. • to portray animal agriculture positively, if done incorrectly, may generate consumer misperceptions When photographing plants, keep the position of the sun in mind to reduce the tendency to capture undesirable shadows.

  22. :Visual Modification/ Manipulation using Camera

  23. Visual Modification/Manipulation Using Camera • Editing images using camera • Adjusting the brightness • Trimming images • Correcting images • Repairing • Copy stamp

  24. i. Editing images using camera • Select an image • Edit the image • Save the edited image

  25. ii. Adjusting the brightness We adjust the brightness of image in the range of -100 to +100

  26. ii. Adjusting the brightness

  27. iii. Trimming images We can trim image according to our desired range

  28. iii. Trimming images

  29. iii. Trimming images

  30. iv. Correcting images We are able to correct images using 2 ways: • Repairing • Copy stamp • Repairing • We can correct an image so that the unwanted spots (spots that we want to delete) on the image blend with surrounding color • Copy stamp • We can correct an image by pasting a section copied from another part of the same image to unwanted part of image

  38. : Media Storage Devices

  39. Media Storage Devices Types of storage devices • Compact flash (CF) • Secure digital (SD) • Multi Media Cards (MMC) • Memory stick • Hard Drives • One-time used flash cards

  40. Types of storage devices 1. Compact flash (CF) • Developed by SanDisk Corp • About the size of matchbook • Offer high storage capacities • Fast processing times • Suitable for video recording

  41. Types of storage devices 2. Secure digital (SD) • Smaller than CF

  42. Types of storage devices 3. Multi Media Cards (MMC) • Even smaller cards • Used in a few pocket cameras

  43. Types of storage devices 4. Memory stick • By Sony Corporation • Shaped like stick of gum

  44. Types of storage devices 5. Hard Drives • Example: Hitachi’s Microdrive • High speed • High capacity
