Photography Terms

1. What do you like to photograph? Be as specific as possible. I like to photograph the details in everyday objects that people normally wouldn't notice.

2. What is the aperture? What does it affect (hint: it affects two things: Light and ______) Controls the amount of light that goes into the camera's sensor. The lower the aperture the lower the opening and the higher the aperture the bigger the opening. Controls depth of field.


3. What is ISO? Measures the sensitivity of the image sensor.


4. What is shutter speed? What does it affect? Controls the amount of time/length of time that light gets through.


5. What is the exposure triad and how do they work together to control exposure? Aperture, shutter speed, and ISO. When you change your aperture your shutter speed and iso also need to be changed.


6. How do you control Depth of Field (DOF)? The lower your aperture the more depth of field you'll have and the higher you aperture the less depth of field you'll have.


7. What is the difference between Shutter-Priority mode, Aperture-Priority mode, and Manual exposure mode? S= Only controlling your shutter speed. A= Only controlling your aperture. M= Controlling both shutter and aperture.


8. What are tonal values? What are different ways to adjust them in Photoshop? Tonal values are the light and dark in photos. 
Brightness/contrast, levels, and curves.


9. What is a histogram? (we'll be talking more about this soon) A diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.


10. What are different kinds of light to use when shooting? Describe each (diffused, direct, existing, artificial, natural, fill, key, flash). Diffused: a soft light that comes from all directions. Direct: light that is direct with no reflections. Existing: light that is available. Artificial: light produced by strobes or other human made lights. Natural: Light produced by the sun or moon. Fill: less intense and softer than a key light. Key: the first and most important light that a photographer uses. Flash: light that is brief and bright.

11. What is the basic image editing process (in Photoshop)? Cropping, re-sizing, and adjusting tonal values.

12. What are different ways to make a selection in Photoshop?

13. Why is it important to use adjustment layers in Photoshop? It is important because if you don't you will lose your original photo.

14. What is an example of an ethical issue in Photography? For example, if photography is meant to be an accurate representation of reality, is it ethical to remove or edit out part of an image for a news story? Find a recent news story that shows is representative of an ethical issue in Photography. What is your opinion about it?
 I think it was wrong of the company to use the photo like that, but this photographer probably signed a contract agreeing to let them use the photo the way they wanted. He should've been more careful about what he agreed to in the contract.

15. Why do you think Photography is important today? Be specific and thoughtful in your response.
Photography has always been an important part of capturing history and the way life changes over the years. It's now needed to do the same. Not only the history of the world, but the history of families, companies, schools, and all the other everyday things in life.

"Essentially, FDNY firefighter Robert Keiley, who does professional modeling in his spare time, did a photo shoot last year that had him styled in firefighter gear. After the shoot, he signed a model release, the image was submitted to Veer for licensing as a stock photo, and it was eventually used in an advertisement by a law firm that represents 9/11 first responders.
The ad features a disclaimer stating that the firefighter is an actor, but Keiley, who joined the FDNY in 2004, started getting flak from his firefighting brethren, and he threatened to sue. He’s upset because the framed photograph he’s holding in the ad was Photoshopped in (at the original shoot, he was holding a fireman’s helmet). You can read the full text of the story here." http://thephotoletariat.com/stock-photography-model-releases-and-fox-news/
