2WHITE 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.
3Auto 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.
4White Balance is measured in Kelvin. Look at the
chart Higher Kelvin temperatures are for
cooler lights and Lower Kelvin temperatures are
for warmer lights.
5This 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.
6RAW 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

7MEGAPIXELS
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.
8RESOLUTION 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.

take the photograph. - Contrast The difference between the darkest
shadow and brightest highlight. - What will contrast say about your subject?
- Saturation How intense/bright a color is. Highly
saturated is making your colors extremely bright.
Desaturating will create a monochrome image. - Color Tone Adding more green or magenta to your
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.
