  • Photography 101: Introduction to Digital Photography
  • OverviewWhat is digital photography? •Tips in Buying a Digicam •Basic Camera Control •Rules of Good Composition • Post Production
  • Digital Photography•is a form of photography that uses digital technology to make images of subjects.•digital photographs can be displayed, printed, stored, manipulated, t ransmitted, and archived using digital and computer techniques,
  • Sensors and Storage VS
  • Advantages of ConsumerDigital Cameras overFilm•Instant review of pictures• Minimal ongoing costs• Photos may be copied from one digitalmedium to another without any degradation• Pictures do not need to be scanned beforeviewing them on a computer• Ability to print photos using a computer and
  • Advantages of Consumer Digital Cameras over Film•Ability to capture and store hundreds ofphotographs on the same media device• Many digital cameras now include an AV-out connector (and cable) to allow thereviewing of photographs to an audienceusing a television• Anti-shake functionality (increasinglycommon in inexpensive cameras) allowtaking sharper hand-held pictures wherepreviously a tripod was required• Ability to change ISO speed settings more
  • Advantages of ConsumerDigital Cameras over Film•Ability to use the same device tocapture video as well as still images.•Ability to convert the same photo fromcolor to sepia to black & white
  • Types of Digital Cameras
  • Types of Digital CamerasPoint and Shootusually have fewer controls than otherdigital cameras but many are alsosmall, bordering on tiny. With a camerathat fits into your pocket, youre morelikely to have it when you need it.
  • Types of Digital CamerasCamera PhonesThe fastest selling point and shoot digitalcameras are those built into camera phones.Camera phone quality is improving rapidlywith 8 Megapixel models already available insome parts of the world. In time thesecameras may present real competition to pointand shoot cameras.
  • Types of Digital CamerasProsumer/ Bridge Camera High-end fixed lens cameras usually have azoom lens and many of the exposure andfocus controls found on SLR cameras. Fixedlens cameras often have great zoom lensesand capture large images.
  • Types of Digital CamerasDSLR- (digital single-lens reflex), these camerasare expensive but have certain advantages overother camera types:• You can change lenses.• You see the scene through the lens so what yousee is what you get.• You can select from a large variety ofaccessories, including powerful flash units.
  • Non-DSLR vs DSLR1. Price: 5,000-20,000 30,000-150,0002. SIZE and WEIGHT:3. Zoom Digital zoom Mechanical Zoom4. Sensor 6.1mm x 4.6mm 23.6mmx15.8mm
  • Non-DSLR vs DSLRNon-DSLR cameras DSLR cameras allow thediffer in that they use a photographer to see theviewfinder or display subject or scene through thescreen to help the optical lens. What you see isphotographer frame the basically what you get in thesubject that is being photo.captured.
  • “what-you-see-is-what-you-get”
  • Buying Digital Camera
  • Understanding the PixelPixel, or pel , (picture element) is a single point (dot) in a graphic image.The number of pixels n for a givenmaximum resolution (w horizontal pixels by h vertical pixels)is the product n = w × h.
  • PIXEL
  • Understanding the Pixel Megapixel: Mega=million Pixel=dote.g.Nikon D60 = 10megapixel 3,648 x 2,736 = 9,980,928 w x h = n
  • 3,648 pixels2,736 pixels
  • Understanding the Pixel 4R 5R 8R
  • Buying Digital CameraLens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the light.
  • LENS
  • Buying Digital Camera Kinds of Lenses1. Kit Lens 18-55mm2. Prime lens 35mm3. Zoom lens 55mm-200mm
  • Buying a Digital CameraImage Stabilization is a family of techniques used to increase the stability of an image. Nikon (Vibration Reduction/VR) Canon (Image Stabilization/IS) Panasonic/Leica (MegaOIS) Sony (Super Steady Shot) Sigma (Optical Stabilization) Pentax (Shake Reduction)
  • Buying a Digital Camera
  • Basic Camera Control
  • Basic Camera Controls READ YOUR MANUAL!
  • The illustration tothe left shows thepath the lighttravels from theobject to thesensor.
  • APERTURE The aperture sits inside the lens and controls how much light passes through the lens and onto the sensor. Knowing how the aperture affects the photograph is one of the most important parts of photography — it affects the amount of light, depth of field, lens speed, sharpness and vignetting among other things.
  • APPERTURE
  • SHUTTER The shutter is what controls how long the sensor is exposed to the light. The longer the shutter is open the more light can be captured by the sensor. A fast shutter speed will result in “freezing” a moving object and a slow shutter speed will let you capture the motion of a moving object.
  • SHUTTERSLOW SHUTTER SPEED FAST SHUTTER SPEED
  • ISO The ISO speed (the name comes from the International Organization for Standardization) is a measure of the film speed, or its sensitivity to light. A low ISO speed requires a longer exposure and is referred to as slow, a high ISO speed requires less time to give the same exposure and is therefore referred to as fast. ISO measures the sensitivity of the image sensor
  • ISO Auto ISO Fortunately most of the time you don’t need to worry about selecting the correct ISO. Most cameras have an “Auto ISO” setting. With Auto ISO, the camera will look at the amount of light in the scene and change the ISO appropriately so that the shutter speed doesn’t get too slow.
  • ISO ValueIf you choose to use a manual ISO, what values should youuse?ISO 50-100. Suitable for bright light (like outdoors on asunny day).ISO 200. Great for overcast or cloudy days.ISO 400 and 800. Use these values when the light isgetting dim but it is not yet night.ISO 1600 and above. Use for indoor or night shots. Alsouseful to freeze the action in sports shots. These valueswill produce the most noise.
  • ISO 100
  • ISO 800
  • Basic Camera ControlsMost shutter buttons havetwo stages.1. When you press it halfwaydown, the camera sets focusand exposure.2. When you press it all theway down, you take thepicture.
