1) We should relate the aperture of a photo to a human eye.
2) The smaller the aperture, the higher the f-stop number. The higher the Aperture, the smaller the f-stop number.
3) Aperture can effect the depth of field, or the amount of stuff in the photo that is clear/blurry. If you are using a larger aperture size, the objects closest to the camera will be clear, while the things in the background will be a bit more blurry. If you use a smaller aperture size, more of the background will be clear, and visible.
Also depending on the aperture value, you can make objects in the center of the photo clear, while objects behind it, and well as in front of it are blurry.
Shutter Speed...

a) high shutter speed
b) semi high hitter speed
c) medium shutter speed
d) medium shutter speed
e) medium-semi high shutter speed
f) high shutter speed
Towards the end when there is no sun and has gotten dark enough that you can't see from one end of the courtyard to the other:
a) medium shutter speed
b) medium shutter speed-semi high shutter speed
c) slow shutter speed
d) slow shutter speed
e) slow shutter speed
f) medium shutter speed
2) One of the setting on cameras for shutter speed is called Aperture Priority. This is when you manually set the aperture value you want, then the camera automatically adjusts the shutter speed to whatever you set the aperture to. A second setting is Shutter Priority. Shutter Priority is the complete opposite of Aperture Priority. You set the shutter speed that you want to use, and then the camera automatically adults the aperture value for you. The third setting on cameras is the Manual Mode. In Manual Mode, you are in complete control of both the aperture size, and the shutter speed.
ISO...

2) The author suggests using low ISO as much as possible, because it will come out with the clearest picture the majority of the time. He especially suggested that when there is more light, you should stay to a very low ISO to capture more detail. If your camera is sitting on a flat area, like a table, or maybe even on a tripod, the author said that you might want to use lower ISO in darker areas, but be careful, because depending on how dark is it, moving objects could come out transparent, like a ghost.
3) The author states that you should increase the ISO number if the light is so dim, that you can't get get a quick picture. He also said that you should use a higher ISO when you are trying to get a picture of something moving fast, because it helps to make it clear. When he is taking pictures inside, he increases the ISO so that the pictures look frozen. He does also say that whenever you are increasing the ISO, be careful about how much you are increasing it, because the higher is ISO, the more grit and grains you can see in the photo.
Sim Cam...
F2.8 - looks best at 1/250 second shutter speed
F4 - looks best at 1/125 second shutter speed
F5.6 - looks best at 1/60 second shutter speed
F8 - looks best at 1/60 second shutter speed
F11 - looks best at 1/60 second shutter speed
F16 - looks best at 1/30 second shutter speed
F22 - I can't decide which looks better, 1/30 seconds shutter speed or 1/8 second shutter speed. 1/30 second is clearest, but pretty dark. 1/8 second had good lighting, but is very fuzzy.
F2.8 - none of the background is visible
F4 - The background is still very blurry, but you can see the darker areas a little bit more
F5.6 - still the background is blurry, but it is better than before
F8 - the background is the same as at F5.6
F11 - the background is almost fully visible
F16 - the background is getting a little bit gritty
F22 - at 1/30 the background is very clear, at 1/8 the background is gritty.
As the shutter speed slows down, the people in the pictures are getting blurry. The lowest shutter speed for this to not happen depends on the aperture size. For example, at F8 I think the slowest shutter speed he photographer can shoot without the people getting blurry is at 1/60 seconds; If the camera's shutter speed is F4, the slowest shutter speed is 1/125 seconds. One way to make this easier on the photographer, is if he used a tripod. The tripod would keep the camera steady on the ground, or the flat surface beneath it, reducing the blur.
