Intro to Photography
• Single Lens Reflex
A single-lens reflex (SLR) camera
typically uses a mirror and prism
system that allows the
photographer to view through the
lens and see exactly what will be
captured.
Types of Cameras
• Digital Singles Lens Reflex
(DSLR) function the same
way as SLRs, except they are
digital and do not use film.
Types of Cameras
Point and Shoot Camera
Is nearly completely
automatic and only gives
the user control over zoom.
The technology used to
capture the image is
different than the SLR.

• ISO (International Standard Organization)
• In traditional photography, ISO referred to the sensitivity
of film to light (the higher your ISO, the more sensitive to
light)
• In digital photography, ISO refers to the sensitivity of
your light sensor. The higher your ISO, the more sensitive
your sensor, and also the grainier your image will be.
Exposure
• Higher ISOs are used in dark settings or to get very fast
shutter speeds in order to freeze motion
• Lower ISOs result in images that are more fine and where
a lot of light is present
Exposure
HIGH ISO
LOW ISO
• Recommended ISO for a bright sunny day:
• 100 or 200
• Recommended ISO for indoors or shady areas:
• 400
• Recommended ISO for night or dark lit places:
• 800 and up
ISO
• Aperture refers to how small or how large you will open
up your lens.
• The opening of the lens determines how much light will
be let in to your sensor.
Aperture is measures in F Stops on your camera
Aperture
• The higher the F stop, the less light you are allowing in
your camera
• High F stops have a longer depth of field, while lower F
stops have shorter depths of field
Low F-stop, short depth
High F-stop, long depth
• Shutter speed refers to how quickly or how slowly the
shutter of the camera is open.
• When the shutter speed is slow, more light enters the
camera.
• When the shutter speed is fast, less light enters the
camera.
Shutter Speed
• The combination of ISO, aperture and shutter speed
determines the exposure of a photo (how the light is
manipulated.

• How do you determine the right settings to correctly
expose a photograph?
Exposure
• Step 1 – Determine the ISO
• Step 2 – Decide what depth of field you want to use
• Step 3 – Use your light meter
