Digital Photography

2. Digital Photography...
A digital camera or dig cam is a camera
that encodes digital images and videos
digitally and stores them for later
reproduction.

3. Photography Basics
One of the first things you will want to
get your head around in photography is
understanding exposure. To do that you
will need to learn some camera basics
and master

4. The Exposure Triangle
Here are three points to help you to understand the
basics of the exposure triangle includes:
ISO
Aperture
Shutter speed

5. Digital Photography
• Formats of Photography – JPEG/RAW
• Megapixels – 4800 pixel x 3600 pixel
• Choosing Camera & Essential Features of a SLR/DSLR
• Advantages & Disadvantages of Digital Photography
• Understanding your Camera
• Focal Length and Magnification - X factor
• Different types of Lenses 18mm-55mm & 18mm-70mm
• Tele Lenses - 55mm-250mm & 55mm-400mm

6. Exposure
Aperture
The aperture stop of a photographic lens can be
adjusted to control the amount of light reaching the
film or image sensor. In combination with variation of
shutter speed, the aperture size will regulate the
film's or image sensor's degree of exposure to light.

8. Shutter Speed
- Shutter speed is one of several methods used to
control the amount of light recorded by the camera's
digital sensor or film.

10. ISO
- ISO stands for 'International Organization for Standardization'
and their speed ratings are used to indicate the relative amount
of light necessary to give a proper exposure. A normal will be
rated at ISO 100. The ISO sequences are: 100, 200, 400,
800,1600, 3200, 6400 and etc.

11. Metering
- Learning to use the different metering modes on
your camera is a skill well worth knowing as it puts in
your hands more control in how your camera
approaches capturing a particular scene.

12. Exposure Compensation
Almost every digital camera sold today comes with a
wide variety of automatic shooting modes, where the
camera decides every setting for you. This is a great
way to start taking photographs, since a full
understanding of the many options available to you
as a photography enthusiast is not a requirement to
taking pictures.

13. Exposure
- In photography, "exposure" is the term used to
evaluate whether or not the image is too bright or
too dark. A correct exposure means the picture is
pleasing to the eye, and the subject of the image is
identifiable.

14. Exposure - Types
1) Underexposed Photography - Underexposure in photography refers
to an image where too little light was recorded.
2) Normal Exposed Photography - Exposure is the amount of light
collected by the sensor in your camera during a single picture.
A properly exposed photo shows details in all parts of the image - light
and dark. - Correct exposure
3) Over exposed Photography - A photograph may be described as
overexposed when it has a loss of highlight detail, that is, when
important bright parts of an image are "washed out" or effectively all
white, known as "blown out highlights"

15. Exposure Bracketing
- It means you have the ability to be able to take three or more
shots of the same scene each with differing exposure, white
balance or flash values.
One is taken with a correct exposure according to the metering
setting on your camera, one is underexposed and one is
overexposed.
The under and over exposed shots can be taken within a range
of + or - 3 stops either way with half or third stop increments.

16. Understand what "exposure of the image" is and how will it
affect your photographs.
Manual Exposure

17. Learn about the "f-stop
Manual Exposure

18. Study your digital camera's "manual exposure" mode.

19. Manual Exposure
Understand why you would want to change the exposure

20. Manual Exposure
Understand why you would want to change the ISO.

21. Manual Exposure
Determine what ISO is required for your shot.

22. Manual Exposure
Stop action by changing the shutter speed on your camera.

23. Manual Exposure
If you are shooting moving subjects, change your shutter speed to a shutter
speed that ranges from 1/500 to 1/1000 to stop the moving subjects.

24. Manual Exposure
If shooting pictures in low light, where you need more light to come in through
the shutter, set the shutter speed to a thirtieth or a fifteenth of a second.
1. Medium shutter speed: 125 or 250 for most pictures.
2. Fast shutter speed: 500 or 1000 for action.
3. Thirtieth or a fifteenth of a second to blur action or under low light.

25. Manual Exposure
Learn how to change the shutter speed on your digital camera.

26. Manual Exposure
Always err on the side of underexposure.

27. Manual Exposure
Learn your camera's "program mode".

28. Manual Exposure
Get familiar with the "aperture priority" mode.

29. Manual Exposure
Investigate your camera's "shutter priority" mode.
