The camera
1. Explain the “camera obscura” effect. How is it achieved?
Camera obscure which is latin for dark room. It was the first camera. It was inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.
2. What invention during the 17th Century helped man get a step closer to creating the modern camera?
In the 17th century, the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3. What were the parts of the first modern camera invented by Niepce?
There were three parts to the small portable camera; A glass lens, a dark box, and film.
4.What do modern digital cameras have in common with Niepce’s camera?
Modern cameras are small so are niepces.
5. What do digital cameras use to capture an image?
The digital cameras do not use old and plastic film they use an electronic sensor called CCD.
Camera modes
6. What is the difference between the Auto Mode and the Program mode?
Auto mode: The camera will completely control flash exposure. on most cameras this is labelled "auto", on others simply "A". Some cameras only have (p)rogram.
Program mode: Automatic-assist, just point the camera and shoot. unlike full auto mode, you can usually control flash and a few other camera settings.
7. What is the Portrait mode used for? How does it work?
Portrait mode is used for attempting to blur out the background, the camera will try to use the fastest available lens setting (aperture).
8. What is the Sports mode used for? (not just sports)
How does it work?
The sports mode is used to freeze motion so the picture won't be blurry, The camera will use the highest shutter motion possible.
The half pieces
9. Why should you do a half press on the trigger button?
You do an half press on the trigger button to focus the image.
Controlling flash
This symbol means no flash, And you use it when your in a room with not much light.
11. What does this symbol mean, when would you use it?
This symbol means auto flash which means the camera will automatically flash if the room needs more light (doesn't have enough)
Introduction to exposure
12. what happens to your photo if there is too much light?
The camera will auto adjust.
13. What happens if your photo if there is not enough light?
The camera will flash.
The universal stop
14. What is a “stop.”
The word stop is used every aspect of photography, it means to represent change in the brightest of light.
15. How many stops brighter is the new planet if there are two suns instead of one?
The new planet will be one stop brighter.
The planet will be four stops brighter.
Shutters and aperture
Shutters and aperture
17. What affect does a longer shutter speed of have?
The picture will have more light.
18. What affect does a shorter shutter speed have?
The picture will have less light.
19. What does the aperture control?
The aperture is like a pupil. you can control the aperture by setting the "aperture opening", also known as the F-stop
20. When adjusting the aperture, how can you increase the amount of light?
You can control the aperture by setting the "aperture opening", also known as the F-stop
