Aperture, Shutter Speed and ISO - what are they?

Aperture, Shutter Speed and ISO - what are they?

Aperture

1. We should relate aperture to the human eye.

F16

F2.8






Shutter Speed


1.  Daylight:  the Stars performance inside the gym, students dancing near the center of the courtyard, the basketball booth where students are shooting basketballs at a hoop
Low Light: a booth in the middle of the yard near the Tree, a food booth outside under one of the big red awnings, people streaming in from the front doors

2. To access your shutter speed, you have three options. Your first is to use manual mode and manually control your shutter speed. Secondly you can use aperture priority mode to pick the aperture you want and the camera controls the shutter speed by its self. Finally you can use shutter speed priority to manually control shutter speed.

2. The smaller the aperture, the more focused the image is on the back and fore ground. The higher the aperture, the more focused the image is on the fore ground rather than back round.

 Aperture affects depth of field by increasing or decreasing the depth of field. When the aperture is larger, the smaller the depth of field. The smaller the aperture, the larger the depth of field.
Low Shutter Speed

High Shutter Speed

ISO

With high ISO, there is more light that the camera is able to detect so the less motion blur you will have.

ISO 200

You should try to use a low ISO whenever you can. A low ISO means a higher quality image. You should use a high ISO when you are in a low light situation. 

ISO 3200

Photo Manipulation and Ethics

Photo Manipulation and Ethics

A.  Photo manipulation is now easier than ever. What took several hours now only takes seconds thanks to new photo technology. Consequently, photo manipulation is now more rampant than ever before and it is almost impossible to tell if the photo has been manipulated.

B. News organizations like the New York Times and the Washington Post have very strict regulations regarding photo manipulation.

C.  I think there is a certain line people can cross while editing a photo. I think it is acceptable to make minor changes to a photo, for example editing how tan someone is in a photo. Something that would be unacceptable would be removing something entirely out of a photo or adding something to the photo.

D. 

The Most Unethical
This photo is very unethical. This photo completely alters the authentic photos and combines them to create an event that never occurred. This photo should have never been allowed and is unacceptable.

E.

The Least Unethical
This photo is not as unethical as others. The editor only made minor changes to the subject's look. This kind of change is acceptable.

Filling the Frame
These two students using blowtorches and the effect it has on the metal makes a really interesting photo. The black back round helps the viewer feel like they are in the photo.

Best action/feeling

The students donating food to the homeless shows the gratitude these men and women show to our generation, no matter how hard their lives are.

Best Story
I believe this photo tells a great story of two students who really enjoy their teacher. These students are joking around with their teacher and helping him with the class.






Best Photo from Academics & Community Service Area

My overall favorite photo from this section is called "Political Secrets". I liked this photo because it captures the feeling of the democratic system and our country in general. This picture shows a woman whispering into the year of an older man's ear on a podium. There is a blurred American flag in the back round of this photo. Rule of thirds, simplicity, and avoiding mergers are both relevant in this photo. 

Next Shoot

I could shoot in various places like a science room, a computer lab, or the library. I'm going to Mr. Mayfield's science room because we are doing a lab, something that's more interesting than taking notes. To take great photos, I will need to use photo composition rules and plan my pictures out. 

9/11 photo composition review

Balance-
The explosion in this photo stretches to both sides of the frame, making a somewhat symmetrical photo. The photographer uses the Twin Towers and the explosion to make a symmetrical photo with a lot of impact. 

Avoiding Mergers-
This is a powerful image of former president George W. Bush and Lt. Lenard Phelan on Ground Zero. These two are the subjects of the photo and are not merged with at all. There is nothing to interfere with the depressing mood of this photo.

Lines-
In this photo, lines is used in a very saddening way. The lines from the tower show the man's downward motion. The lines show the man is falling, as well as the tower.

Rule of Thirds-
Using rule of thirds, the photographer captured the tragedy that was 9/11. This area of New York before the destruction would be bustling would lots of faces, but with just one single man city looks almost  post apocalyptic.

Framing-
The photographer for this photo made sure to frame the silhouette of the destroyed building to give
the photo a sense of scale and show how devastating 9/11 really was.

Simplicity-

The photographer from this photo made sure that the man was in the center of the frame
and was focused on. The viewer's attention is directly at the man.

The Camera Notes

The Camera and very intriguing notes I am taking on it.

• The “camera obscura” effect is achieved by making a tiny hole in a dark room and then focusing on the small point of light. The hole would act as a lens. This was the first camera.
• The understanding of optics and the creation of a high quality lens, perfected by Issac Newton and Christian Huygens.
• Glass, a dark box, and film were used in Joseph Nicéphore Niépce's camera.
• Digital cameras use an electronic sensor or a CCD.

Camera Modes

• Auto mode takes complete control of most of the camera, while with program you can control some things like flash settings.
• Portrait mode is when the camera will lower the aperture of your camera for a blurry back round.
• Sports mode is to make the shutter speed as high as possible. 

The Half Press

• You should half press the shoot button to confirm your camera is ready to take a photo.

Controlling Flash

• This symbol means no flash. You would use no flash when you want to capture a certain mood in a photo.
• This symbol means automatic flash. You would use this when you need more light.

Introduction to Exposure

• If your photo has too much light, it will be over exposed and parts of your photo will be very white.
• If there is not enough light, your photo will be under exposed an will be very dark.

Aperture and Shutter Speed

• Longer Shutter speed means more light.
• Shorter means less light.
• Aperture controls the opening and closing of your lens.
• If you want to increase the light with aperture, you decrease it.
