The Camera


The Camera
1. The "camera obscure" effect is Latin for "dark room". In a pitch black room, a small hole is made in one wall, and through the hole, light is focused, causing the projection to appear on the wall ahead of it upside-down.
2. In the 17th century, it was Isaac Newton that was a step closer to modern day's camera.
3. The parts of the first modern camera were a glass sense, a dark box, and film.
4. Modern digital cameras and Niepce's camera both still make photos, and basically the same way; light passes through the lens, into the camera, and exposes the film.
5. Instead of using plastic film, digital cameras capture images with an electronic sensor called a CCD.

Camera Modes
6. Auto mode controls the flash and exposure all by itself, you don't have to do anything. With program mode, you can control the flash and a few other camera settings.
7. Portrait mode blurs the background of the picture, the camera uses the fastest lens setting available.
8. The sport mode is used to freeze motion. In order to do this, the camera uses the fastest shutter speed possible.
9. In manual mode, the photographer has to set both the shutter and the aperture mode.


The Half Press
10. Doing a half press on the the trigger button is helpful because it has faster camera response time, more control over focus, and encourages better composition. 


Controlling Flash
11. This symbol means that flash is disabled. You would use no flash in many situations; if the mood of the picture isn't bright, if there is no need for extra light in the picture, and if you want to reduce the amount of glare. 
12. This symbol means that flash is automatically enabled. The flash will automatically go off if the camera thinks there needs to be more light.


Introduction to Exposure
13. If there is too much light, the picture will be washed out, and everything will be too white or bright to see what the picture is actually of.
14. If there is not enough light, the picture will be too dark, and you won't be able to see what the picture is of.


The Universal Stop
15. A "stop" is a relative measurement of light: the change in the brightness of light.
16. If there are two suns instead of one, the new planet is one stop brighter.
17. If there are four suns, the new planet is two stops brighter.


Shutters and Aperture
18. A longer shutter speed gives the film more light.
19. A shorter shutter speed gives the film less light.
20. The aperture controls the amount of light let in.
21. When adjusting the aperture, you can increase the amount of light by changing the size of the aperture's opening.

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
