Aperture, Shutter Speed and ISO

                                                       

   Three pillars of photoagrphy

Aperture

1. You can relate aperture to the human eye

2. The smaller the aperture number the higher the aperture diameter

3. Aperture brings light into the camera and controls the amounts of light that enters the camera

4. The F-Stops go to 3.5 through 22

5. The highest aperture numbers are 3.5 and 22

      Low Aperture                                                             High Aperture

Shutter Speed

1.  The shutter speeds are 1/4, 1/5, 1/6, 1/8, 1/10, 1/13, 1/15, 1/20, 1/25, 1/30, 1/40, 1/50, 1/60, 1/80, 1/100, 1/25, 160, 1/200, 1/250, 1/320, 1/400, 1/500, 1/640, 1/800, 1/1000, 1/1250, 1/1600, 1/2000, 1/2500, 1/3200, 1/4000

                           

                              Fast Shutter Speed                                                    Slow Shutter Speed

ISO

1. The advantage is that the higher the ISO is the brighter the picture, which is good during the night

2. low ISO makes the pictures darker
3. Higher ISO makes the pictures brighter
4. The ISO goes through 1 to 1/32

                         

                         Low ISO                                                                   High ISO
