Keep it simple. The word Photography comes from two Greek words that mean "writing with light” Perfect Exposure Goal: To obtain the amount of light needed to create the desired image using the combination of these three variables: Aperture Shutter Speed ISO. Camera Modes.

Keep it simple • The word Photography comes from two Greek words that mean "writing with light”Perfect Exposure Goal: • To obtain the amount of light needed to create the desired image using the combination of these three variables: • Aperture • Shutter Speed • ISO
Camera Modes • P = program mode Subject ModesPortrait Macro Landscape Sports Night AV or A = aperture priority mode TV or S = shutter priority mode *M = manual mode
Who Decides what in each mode?Aperture and Shutter speed • P=Program mode • AV or A= aperture priority mode • TV or S= shutter priority mode • M=manual mode You decided: NONE. The camera decides: APERTURE & SHUTTER SPEED. You decide: APERTURE. The camera decides: SHUTTER SPEED. You decide: SHUTTER SPEED. The camera decides: APERTURE. You decide: SHUTTER SPEED and APERTURE The camera decides: none.
Manual mode • Why shoot in Manual mode? For consistent results and creative control.
aperture • Aperture is size of the opening of your lens. • It is used to control the amount of light reaching the sensor of your camera and controls depth of field, or area in focus.
aperture The smaller the number = larger opening, more light and more shallow depth of field The larger the number = smaller opening, less light and greater depth of field

Shutter speed • -Shutter speed is unit of measurement which determines how long the shutter remains open as the picture is taken. • -Shutter speeds are measured in a fraction of a second, so 125 is 1/125 of a second. • -Shutter speed controls the amount of light reaching the sensor and can freeze or blur motion.

iso • International Organization for Standardization • Is a measure of how sensitive your camera is to light • The lower number, the lower your camera’s response is to light • The higher number, the more sensitive it is to light • Generally you’ll want to keep as low a number as possible to ensure a less noisy or grainy image
Metering Modes • Evaluative/Matrix • Center weighted • Spot
