1. Explain the “camera obscura” effect. How is it achieved?
The Camera Obscura effect was created by Greek and Chinese philosophers in approximately 500BC. How it worked was that inside a dark room, a small hole was formed into a wall. When light shined through the hole it focused on the outside scene (upside-down) on another wall.
2. What invention during the 17th Century helped man get a step closer to creating the modern camera?
The understanding of the process of making high quality glass lenses and optics was perfected by Isaac Newton and Christian Huygens.
3. What were the parts of the first modern camera invented by Niece?
A dark box, a glass sense, and invented by Niece, film, were the parts of the first modern camera.
4.What do modern digital cameras have in common with Niepce’s camera?
Modern camera's still have light pass through the lens, into the camera, and exposes the film. The end result is still a photograph!
5. What do digital cameras use to capture an image?
Digital cameras use an electronic sensor called a CCD.
6. What is the difference between the Auto Mode and the Program mode?
Auto mode comepletely controls the flash and exposure. Program is just automatic assist. You just point and shoot.
7. What is the Portrait mode used for? How does it work?
Portrait mode is when the camera uses the fastest available lens setting in attempt to blur out the background in a photo.
8. What is the Sports mode used for? (not just sports) How does it work?
Whatever camera, the highest shutter mode will be used to capture or freeze subjects in motion.
9. What does the photographer have to do in Manual Mode?
The photographer must set the shutter and the aperture mode.
10. Why should you do a half press on the trigger button?
You want to half press because it will focus on the subject you are shooting.
11. What does this symbol mean? When would you use this?
This symbol means there is no flash. You would use this whenever you want to establish a mood.
12.What does this symbol mean? When would you use this?
This symbol means that flash will fire. You would use this when you or the camera thinks you need more light.
13. What happens to your photo if there is too much light?
The photo will be washed out.
14. What happens to your photo if there is not enough light?
The photo will not look like how it looked in "real life".
15. What is a “stop.”
A relative measurement of light.
16. How many stops brighter is the new planet if there are two suns instead of one?
It is one stop brighter.
17. How many stops brighter is the new planet if there are four suns instead of two?
It is two stops brighter.
18. What affect does a longer shutter speed of have?
There will be more light.
19. What affect does a shorter shutter speed have?
There will be less light.
20. What does the aperture control?
How much light passes through to the photo.
21. When adjusting the aperture, how can you increase the amount of light?
Have a larger opening.
