Aperture, Shutter Speed and IOS


Aperture

Here is an example of f/2.8 aperture
Now here is an example of f/16 or higher aperture 

1.  The pupil in the eye acts like aperture in the sense that it opens and closes.  It only lets a certain amount of light through, thus changing the focus.
2.  The smaller the aperture the more focused the image is, the higher the aperture the larger the area of focus.  
3.  Aperture is a way of telling you what to look at.  

Shutter Speed

Here is an example of slow shutter speed

Now here is an example of fast shutter speed
a) You could probably use a medium shutter speed since there isn't too much action, but there is still movement.  
b) A slow shutter speed would be good since there is minimal movement.  
c) You would need a fast shutter speed since there is a lot of action.  
d) Once again, you would need a fast shutter speed because of the large amount of movement.  
e) A medium shutter speed would probably be best, since it shows the motion of the crowd, but it still isn't blurry.  
f) A fast shutter speed would be best so you it wouldn't be blurry.  

a) You should use medium to fast shutter speed since there isn't too much action, but there is still movement.  
b) A slow shutter speed would be good since there is minimal movement.  
c) You would need a fast shutter speed since there is a lot of action.  
d) Once again, you would need a fast shutter speed because of the large amount of movement.  
e) A medium shutter speed would probably be best, since it shows the motion of the crowd, but it still isn't blurry.  
f) A fast shutter speed would be best so you it wouldn't be blurry.  
2.  The first setting is auto; the camera choses the shutter speed for you.  The second is Aperture Priority setting.  

ISO
Here is an example taken at 200 ISO
Here is an example of 3200 ISO
Here is an example of 6400 ISO

Script

Outside-In tree-night KATNISS climbs a tree slowly and quietly hoping to escape from her enemies below. She went up and up high on the tree so her enemies wouldn't catch her for a while. She then finds a safe spot hidden high upon the tree using a rope to attach herself to the tree to sit down and rest. The next morning, KATNISS sees the beehive and starts to climb up the tree toward it quietly. CEASER is sitting in a dark newscasting room "For those of you that don't know, Tracker Jackers, are genetically engineered Wasps whose venom causes searing pain, powerful hallucinations and in some cases death." She eases along the tree to reach the beehive, getting stung multiple times. She uses a knife that was thrown at her to slowly (takes a long time) cut the beehive down. The beehive lands on the people and the bees sting them vigorously. They scream and one of the girls falls and dies (GLIMMER). After the bees clear out and the people are running away fro

Huntington Story

At 10 PM. on Wednesday one Janice Jones was eating a pork chop in her trailer.  As she was eating her dog knocked a 9 millimeter hand gun off of a table.  When it hit the ground, it went off and hit Janice in the leg.  The bullet continued traveling and lodged itself only two inches from the gas tank.  Jones was rushed to a hospital in Huntington Beach.  Later she was transported to a hospital in Irvine California.  Her dog was kept with Animal Control officers where they discovered that it was malnourished and had multiple cigarette burns.  However, that was not the only illegal thing Jones had done.  The police searched her trailer and found that the handgun had been purchased illegally.
