Transcript

  • 1. Fundamentals of Digital Camera
    Level : Intro
  • 2. Types of Digital Cameras
    Broad classifications
    - Point and Shoot
    - Prosumer*
    - Digital SLR
  • 3. Point and Shoot digital Cameras (P&S)‏
    - Commonly referred to as “consumer” digital cameras.
    - Represent probably 70% of all digital cameras on the market
    - Typically small, compact and lightweight
    - Targeted at broad majority
    - Typically very User-Friendly
    - Image Quality has improved drastically
  • 4. Prosumer Digital Cameras
    - Common term used to describe advanced models of P&S
    (now also used to describe many entry level DSLR's)‏
    • Similar in shape and appearance to Digital SLR's
    - Typically have extended zoom range‏
    - Typically combine user friendly
    P&S features with more advanced
    manual features.
  • 5. Digital SLR (DSLR)‏
    SLR Stands for Single Lens Reflex
    - Have larger sensors, resulting in greater image quality
    • Favor manual setting for complete photographic control.
    • 6. Lacking many automatic settings found on P&S
    - Much larger and heavier
    - Ability to interchange system lenses
  • 7. REAL difference
    So What is the REAL difference between a digital SLR and a point and shoot camera?
  • 8. The short answer is.....Image Quality
    But Why?
    How can a 6 megapixel setting in DSLR take a better picture than a 14 megapixel point and shoot?
  • 9. Ah!! because Size Matters!
    All Pixels or dot are not created equal!
    - Larger Sensors contain larger pixels, which are much better in collecting light data or information.
  • 10. Digital Camera - Fundamentals
    - More MP does not always mean a better picture
    - Digital Image dimensions do not equal print dimensions
    Megapixels Vs. Print Size
  • 11. Getting a “Good” shot
    While there are hundreds of factors which can make a photo “good”, it is still a relative term, and good to one person may not be good to someone else.
    For our purposes we will refer to good in the sense of a correct exposure.
  • 12. Exposure
    A “correct” or “good” exposure
    occurs when you maintain as much detail
    as possible in both the very bright parts (highlights)
    as well as the very dark parts (shadows) of an image.
    How much of a range in which you
    can capture detail from light to dark
    is referred to as the Dynamic Range.
    There can be many
    “correct” or “good” exposures.
  • 13. There are 3 factors which influence
    the exposure of your image:
    -Shutter Speed
    -Aperture
    -ISO
  • 14. Shutter Speed
    Refers to how long the shutter is open, exposing the image sensor to light (how long the camera “sees” the picture)‏.
    Measured in Seconds, from 30 down to 1/8000
    Fast Shutter Speeds are used to stop motion and will freeze the subject.
    Slow Shutter Speeds (1/60 or slower) can be used to portray movement.
    Fast Shutter
    Slow Shutter
  • 15. Shutter Speed
    Very Slow Shutter Speeds (5 sec. or slower) can be used in very low light situations to obtain correct exposure, or achieve dramatic effects.
    Beware!
    As your shutter speed decreases, your chances of getting a blurry image increase because you must hold the camera steady for a longer period.
  • 16. Aperture
    Inside the camera lens is a system of blades which open and close to increase or decrease the opening through which light passes into the camera (a hole or opening through which light is admitted)
    Often referred to as an f-stop
    A Smaller f # means a wider opening and more light gets in (can use faster shutter speeds)‏ and vice versa.
  • 17. Depth of Field
    Aperture also controls depth of field (DOF), which refers to how much of your image is in focus.
  • 18. ISO
    Refers to the light sensitivity of the sensor
    HIGH ISO value means the sensor will be MORE sensitive to light, meaning it will take LESS LIGHT to get the right exposure
    Note:
    Using High ISO values causes the sensor to produce much more heat, which creates digital “noise” in images.
    Noise is similar to grain and causes loss of fine detail in images.
    It is more visible in dark parts of an image and is generally more noticeable when displayed on screen than in print.
  • 19. The fourth Element - White BALANCE -
    White balance doesn't really affect your exposure, just the appearance of colors in the image.
    Different light sources cast their own colors, which cannot usually be noticed with the naked eye.
    White Balance is essentially the camera compensating for the color cast of the light in order to reproduce the “correct” colors.
  • 20. Fundamental Principle
    Exposure
    Brightness , Aperture, Shutter, Sensitivity
    “Bokeh” Depth of field
    Aperture (distance, Focal length, sensor size)
    Time control
    Shutter, Shaking
    Color
    Color Balance, White Balance, Picture Style
    Lay out
    Composition, Framing, Focal length
  • 21. In-Camera Settings
  • 22. EXPOSURE MODES
    There are several modes available which offer a combination of automatic and manual control over the three elements of exposure.
    Auto, sometimes represented by an A, or simply a green square, is fully automatic functioning. True “point and shoot” where the camera decides all the settings for you
  • 23. CREATIVE ZONE
    Av or Aperture Priority allows you to choose the aperture value while the camera chooses the shutter speed required to obtain a correct exposure.
    Tv or Shutter Priority allows you to choose the shutter speed while the camera chooses the aperture which would produce the correct exposure.
    M or Manual gives you complete manual control. You choose both shutter speed and aperture.
  • 24. BASIC ZONE – SCENE MODES
    Scene Modes are fully automatic modes designed specifically for a certain situation. They typically place emphasis on one or more settings based on the typical circumstances of the situation chosen.
    Most digital cameras have very similar scene modes available.
  • 25. Metering Modes
    The metering system within a camera measures the amount of light in a frame and determines the best exposure. Many cameras have more than one metering mode and each evaluates a scene in a different way. Essentially, by changing the metering mode you are telling the camera to evaluate the scene in a different way.
  • 26. Metering Modes
    Exposure metering is averaged over the entire frame with emphasis placed on the central area. Used for general and portrait photography.
    It takes a precise exposure reading only at the very center of the frame and disregards the rest. A spot meter is used when a subject is backlit or has bright light upon it and the background is dark.
    Partial metering is similar to spot metering but covers a larger area . Useful for taking portrait when the subject is back lit.
    A metering system whereby a scene is split up into a series of zones then evaluating each zone individually and taking an average of the total light readings.
  • 27. Photography Rules & Techniques
  • 28. The Rule of Thirds
    is based on the fact that the human eye
    is naturally drawn to a point
    about two-thirds up a visual.
    Compose or crop your photo
    so that the main subjects are located
    around one of the intersection points
    rather than in the center of the image.
  • 29. Rule of Thirds
  • 30. The Golden Section Rule.
    Many natural or man-made objects and scenes
    with certain proportions
    (whether by chance or by design)
    instinctively please us.
    It has been found that certain points
    in a picture's composition automatically
    attract the viewer's attention.
    Imagine a picture divided into 9 unequal parts with 4 lines.
    Each line is drawn so that the width of the resulting small part of the image
    relates to that of the big part exactly as the width of the whole image
    relates to the width of the big part.
    Points where the lines intersect are the "golden" points of the picture.
  • 31. Golden Rule
  • 32. The Diagonal Rule
    a photograph looks more dynamic
    if the objects fall on or follow a diagonal line.
    The diagonal line doesn't have to be an actual line
    and it doesn't have to be a straight one.
    Linear elements, such as roads, waterways, and fences
    placed diagonally, are generally perceived as more dynamic
    than horizontally placed ones.
  • 33. Diagonal Rule
  • 34. The Golden Triangle Rule
    3 triangles with corresponding shapes.
    Just roughly place 3 subjects with approx equal sizes
    in these triangles and this rule will be met.
  • 35. Golden Triangle
  • 36. The Golden Spiral Rule
  • 37. Golden Spiral
  • 38. Framing
  • 39. Trimming, Crop
  • 40. Don't be afraid of breaking rules!
    As Edward Weston said,
    "Consulting the rules of composition
    before taking a photograph
    is like consulting the laws of gravity
    before going for a walk."
