Photography 101 LESSON

Digital Single Lens Reflex

DSLR

A camera lens is an

OPTICAL ASSEMBLY OF LENSES used to bring light into the digital sensor of your camera.

LENS

Component that

DETECTS LIGHT and CONVERTS LIGHT into an IMAGE.

CAMERA

SENSOR

A camera component between the lens and the sensor, that opens and closes to let light in.

CAMERA

SHUTTER

a mechanism in the lens that controls the amount of light admitted into the camera.

ISO is your sensor's SENSITIVITY to light

ISO

ISO is your sensor's SENSITIVITY to light.

1. It makes the image look darker or brighter.

ISO

ISO is your sensor's SENSITIVITY to light.

2. Lower ISO = LESS sensitivity to light

   Higher ISO = MORE sensitivity to light

ISO

Digital Noise:

The grainy appearance of

photos taken at HIGH ISO settings

1. Darkens or brightens an image

2. Measured in Decimals & Whole Numbers

APERTURE

(F-STOP)

3. aperture stop (f-stop) can be adjusted to control the amount of light reaching the image sensor

4. This also controls the Depth of Field (DOF)

APERTURE

(F-STOP)

DEPTH OF FIELD (D.O.F.):

The distance between the nearest and furthest elements in a scene that appear to be SHARP or in FOCUS in photograph.

APERTURE

(F-STOP)

DEEP or LARGE (D.O.F.)

More things are in focus

APERTURE

(F-STOP)

​f11 to f22

SHALLOW or SMALL (D.O.F.)

Less things are in focus
