Aperture, Shutter Speed, & ISO

Aperture

Aperture F2.8
Aperture F16








1.) The part of the body that closest relates to aperture is the pupil. 
2.) The smaller the Aperture size, the higher the Aperture number.
3.) If the aperture is small, both the foreground and the background are focused. If it's a large aperture, the foreground will appear very focused, while the background is blurred.


Shutter Speed

Slow Shutter Speed







High Shutter Speed











1.)
At the beginning while the sun was still up and the courtyard had reasonable good light:

 a.) a booth in the middle of the yard near the Tree: High
b.) a food booth outside under one of the big red awnings: Slow
c.) the Stars performance inside the gym: High
d.) students dancing near the center of the courtyard: High
e.) people streaming in from the front doors: High
f.) the basketball booth where students are shooting basketballs at a hoop: High

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.) a booth in the middle of the yard near the Tree: Slow
b.) a food booth outside under one of the big red awnings: Slow
c.) the Stars performance inside the gym: High
d.) students dancing near the center of the courtyard: Slow
e.) people streaming in from the front doors: High
f.) the basketball booth where students are shooting basketballs at a hoop: Slow

 2.) 3 settings regarding the shutter speed:

 -Aperture Priority: You are in control of the lens aperture, but the camera's shutter speed is pre-set.
-Shutter Priority: The opposite of Aperture Priority, you choose the shutter speed you want your camera to be set at, and the camera automatically sets the aperture. 
-Manual: You are in control of both the aperture and the shutter speed, you set them both.

ISO
 200 ISO
3200 ISO






1.) What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game?: The higher the ISO, the more light there is in the picture, without using the flash.
2.) What suggestions did the author make about using a low ISO?: You should always try to use the lowest ISO as possible, as to not add grain to the picture. The lower the ISO, the higher quality the picture is. 
3.) What suggestions did the author make about using a high ISO?: The ISO should be increased when there is not enough light for the camera to be able to get a good picture fast.

Is it ethically acceptable to change a person's appearance like these in a photo? Why or why not? No, it is not acceptable period to change a person's body to make it look "perfect". It's unethical because people should be comfortable enough in their own skin so that they don't want to have their body altered. It also sends the wrong message to people, making them think they need to look like that

Personal Essays

1. One idea the article gave me that I can use to decide on a topic is to make sure I feel very strongly about the subject. It doesn't matter if it's something big or small, as long as you have very strong opinions about it. 2. An idea from the article I should keep in mind while writing the piece is to write kind of like I'm talking, loose and comfortable. Also I should make sure to include many details to ensure that the readers can relate to my story. 3. One idea that I will keep in mind is the many different types of hooks. You can hook the audience with a question, metaphor, a quote, and more.

Front Pages of the World

My favorite nespaper front page is the one for Albany, New Yorks's Times Union. This is because it has many differnt stories and there will be at least one that would appeal to someone. My favorite headline from the newspaper is "Their generous hearts helping others" because it appeals to my emotions. Especially with a baby being the picture, it makes me want to read more about what was happening in the picture. On the front page there are six different stories. After seeing all of the front pages for the various newspapers I looked at, I noticed that they all have huge text in bold letters for the headline in the top center of the page, usually paired with a large picture, to grab people's attention. Differences I saw between some of the front pages are the amount of stories and also the main stories. For example, in Austin's front page the biggest headline is about Karolyi Ranch and how many gymnasts were abused there and how it is to be investigated. Whereas in
