Question 1

ISO

Answer 1

Determines the sensitivity of the camera sensor. ISO stands for International Organization for Standardization, but the acronym is used as a term to describe the sensitivity of the camera sensor to light. The higher the sensitivity, the less light is required for good exposure. These values are a carryover from the days of traditional color and black-and-white films.

Question 2

Aperature

Answer 2

Also referred to as F-STOP, this determines how much light passes through the lens at once.

Question 3

Shutter Speed

Answer 3

Controls the length of time that light is allowed to hit the sensor.

Question 4

ISO

Answer 4

100: FULL sun and NO shade
200: Lots of sun, could be in partial shade or an overcast day out in the open
200: INSIDE on a sunny day, directly by a large widow.
400: In the shade on a sunny day or under a covered area on an overcast day
700: INSIDE on a SUNNY day or under a covered area on a OVERCAST day
640-800: Sun is starting to set and less light
800: Inside, quite a distance from a window (SUNNY OUTSIDE)
850-1000: Inside, quite a distance from a window (overcast day)
1250: Inside during the EVENING, light bulbs are the only source of light.
1600: Inside a dark room where there is a light source(theatre, school production, etc)

Question 5

SHUTTER SPEED Cheat Sheet

Answer 5

Shutter Speed Motion
1/4000 Sec. Freezing very fast objects
1/2000 Sec. Freezing fast cars/birds
1/1000 Sec. Motorcycles, cars, sports
1/500 Sec. Mountain bikes, slow sports
1/250 Sec. Freezing slow moving people, kids
1/125 Sec. Panning motorcycles, cars
1/60 Sec. Slowest hand held
1/30 Sec. Panning fast bikes, cars, sports
1/15 Sec. Blur moving objects
1/8 Sec. Blur fast moving water
1/4 Sec. Blur people walking
1/2 Sec. Blurring slow moving water
1 sec or slower. “Milky” water /very long exposure

Question 6

PHOTO BASICS

Answer 6

* IF ITS TO BRIGHT
   Increase your shutter speed 
    Pick a bigger F-Stop#
   Increase your ISO
*  IF ITS TO DARK
   Decrease your shutter speed
   Pick a smaller F-Stop #
   Increase your ISO
*. WANT SHARPER IMAGES
    Shutter speed is >= Focal length
* Sunny 16 Rule - Sun on subject
  F/16 Aperture + ISO = Shutter Speed
  So ISO 100 Shutter Speed 1/100 @ F/16
* WHAT APERTURE IS GOOD FOR GROUPS
   F/stop >= Number of Subjects
* DEPTH OF FIELD
    Small F-Stop= Shallow big F-stop = depth
