Intro to Photography

Types of Cameras

• 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.

Exposure

• 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

HIGH ISO

LOW ISO

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

Aperture

• 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

• 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

• 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.

Exposure

• The combination of ISO, aperture and shutter speed determines the exposure of a photo (how the light is manipulated.

Overexposed

Underexposed

Exposure

• 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
