Slide 2
Questions to consider What is the purpose of taking personal
(non-business) photos? What qualities makes a good photo?
Slide 3
Composing a Picture Take time to compose each photo as a work
of art. Frame the content in a manner that focuses attention on the
subject, and omits unnecessary distractions. Be creative!

Focus, Zoom, Focal Point Photographic lenses have varying focal
points; distances at which they are able to focus. Normal Lense:
have a "natural" perspective, focal point of 28 mm - 35 mm Wide
Angle Lense: focal point of 24, 21, 18 and 14 mm Telephoto Lens;
Focal point of 35 mm - 1700 mm In digital cameras optical zoom
provides a range of lens options from wide angle to telephoto
Autofocus fine tunes the focal point

Slide 5
Consider Lighting Light direction has a big impact! Sunlight on
the lens creates a flare, which can be a nice effect, but is often
undesirable. Shading the lens solves the problem.
Slide 6
Histograms A histogram shows which parts of the light spectrum
are used in a photo.

Slide 7
Fill Flash Use a flash outdoors to brighten backlit objects, or
make your foreground objects stand out.
Slide 8
Indoor Flash Indoor flash is too bright for close- ups and
produces harsh shadows. Use natural light whenever possible.
Slide 9
Types of Light Different types of light effect the color
quality of photos. White balance setting is used to compensate.
Cameras often include settings to automatically correct lighting
problems. daylight, cloudy, tungsten, fluorescent, flash Some
cameras allow you to custom set the white balance by focusing on a
white surface.
Slide 10
Exposure The quantity of light allowed to act on the
photographic material in the camera.

Slide 12
Exposure = Shutter Speed + Aperture Size
Slide 13
Shutter Speed Shutter speed refers to the amount of time the
lens shutter remains open during the photo. A fast shutter speed
will freeze the subject and a slow shutter speed will make it look
blurred as the subject moves.

Aperture The aperture is the lens diaphragm opening inside a
photographic lens. The aperture size can be adjusted to regulates
the amount of light that passes through the lens. The aperture size
is adjusted in discrete steps, known as f-stops (f for focal) The
larger the value the smaller the lens aperture, the less light
intensity.
Slide 18
Depth of Field Depth of field is the amount of distance between
the nearest and farthest objects that appear in acceptably sharp
focus in a photograph. A few factors may have a direct relationship
with depth of field, they are: 1) the Aperture, 2) the focal length
of the lens in use, and 3) image size. This photo has a shallow
depth of field (only the foreground is in focus) and was taken
using a larger lens aperture a low f number.
Slide 19
Depth of Field These photos have a deep depth of field (the
foreground and background are in focus) and were taken using a
small lens aperture - high f number.
Slide 20
F-numbers Use larger aperture (smaller number like f/2.8, f/2.0
etc.) with a long focal length to isolate or emphasize the subject.
Use a smaller aperture (bigger number like f/16 or f/22 etc.) to
ensure pin-sharp details in both the foreground and the background.
Depth of field increases with f-number!! f/22f/2.8
Slide 21
Shutter Speed + Aperture Since both shutter speed and aperture
size effect the amount of light, they can be balanced one against
the other to provide consistent light, and a wide variety of
effects.

Editing Photos
Slide 26
Photo-editing Software Photo-editing software, like Photoshop,
allows you improve digital photos, and create interesting effects:
Resize and crop images Cut and paste portions of one image on
another Adjust brightness, contrast, hue, and saturation Apply
special effects Demo Photoshop
Slide 27
Brightness/Contrast Brightness adjustments increases intensity
evenly across the RGB spectrum. Contrast adjustments make dark
colors darker and light colors lighter.
Slide 28
Hue /Saturation Hue settings apply color filters to a photo to
move color settings up or down the color spectrum. Saturation
settings increase or decrease the intensity of all colors in the
photo.
Slide 29
Cut & Paste Using the lasso tool, objects in a photo can be
selected and copied. Once copied they can be pasted into other
photos to create interesting effects, or faked photos.
