• Resolution Megapixels
• Camera Settings

WHITE BALANCE

• Set your white balance for every digital
  photograph you shoot/every time you change
  scenery.
• ONLY for digital photography.
• if its cloudy out, set your white balance to
  cloudy as shown in photo.
• White Balance helps you get correct and natural
  colors in your photographs.
• If your white balance is set incorrectly the
  colors in your photograph will be unrealistic.

Auto white balance is available and usually will
work to your advantage, but it is highly
suggested that you manually choose your own. This
photograph was shot under incandescent lights
choosing that white balance created a realistic
color tone in the photograph.
4
White Balance is measured in Kelvin. Look at the
chart Higher Kelvin temperatures are for
cooler lights and Lower Kelvin temperatures are
for warmer lights.

This photo was taken with the wrong color balance
it is bluer/cooler than in reality. You can fix
this is Adobe Photoshop by changing the color
balance in your image adjustments.

RAW vs. JPEG

• When you photograph, your image sensor converts
  the image
• information into a data file.
• You can adjust your camera to shoot JPEG or Raw
  Image Files.
• You can also adjust the quality of your Raw or
  JPEG files.
• You can even save each photograph as both a Raw
  and a JPEG
• file at the time of shooting.
• RAW FILES After shooting you can open this
  photograph up on your computer and adjust your
  exposure time (shutter speed/aperture), white
  balance setting, contrast, saturation, sharpness
  and color tone WITHOUT using Adobe Photoshop. You
  can only open this file on a compatible computer
  system. (blabla.CR2)
• JPEG FILES Image file that is unchangeable. You
  can open this file on any computer. (blabla.jpeg)
• OTHERS .doc word document, .psd photoshop

MEGAPIXELS
Pixel Count. How many pixels does your camera
have? 1 megapixel 1 million pixels. It not only
counts the amount of pixels in an image but
represents the number of elements on a digital
display. A digital image is made up of millions
of pixels. A pixel is the smallest single
component of a digital image. Pixels refer to
many different topics digital printed
photographs, digital images on a camera, plasma
and LCD T.V. screens, computer screens,
etc. Zoom far into a digital image on
your computer and see it get pixilated. The
more megapixels your camera has, the larger your
image is.

RESOLUTION The clarity of a photograph.

• The higher the resolution, the more image
  detail.
• Resolution and Pixels go hand in hand.
• Resolution is usually measured as the amount of
  pixels in height x the amount of pixels in width.
  (640 x 480)
• When you multiply the number of pixel columns
  with pixel rows you get a total number of pixels
  in an image measured in Megapixels.

  image to counteract lighting issues and help with
  white balancing.
• Sharpness Creating crisp, clear and sharp images
  via optical illusion by changing edge contrast
  and making pixels more defined.
