1. Explain the “camera obscura” effect. How is it achieved? Camera obscura is known as the dark room, the hole was like a lens making the light go threw to make it project to the wall in the dark chamber.
2. What invention during the 17th Century helped man get a step closer to creating the modern camera? Isaac Newton and Christian Huygens made the glass lenses better so they perfected them.
3. What were the parts of the first modern camera invented by Niepce? The parts of the first modern camera were the glass lens, dark box, and film. But Niepce was the one who added the film.
4.What do modern digital cameras have in common with Niepce’s camera? Light passes through the lens, into the camera, and exposes the film.
5. What do digital cameras use to capture an image? Digital cameras capture an image by an electronic sensor called CCD.
6. What is the difference between the Auto Mode and the Program mode? Auto mode controls flash and exposure, in program mode you have to set up the flash and other camera settings.
7. What is the Portrait mode used for? How does it work? To blur out the background, it uses the fastest lens setting.
8. What is the Sports mode used for? (not just sports) How does it work? To freeze motion, the camera will use the fastest shutter speed possible.
9. Why should you do a half press on the trigger button? It focus the image better.
10. What does this symbol mean? Disable Flash
When would you use this? When the camera isn't disposed to the natural light.
11.What does this symbol mean? Auto flash
When would you use this? the camera will automatically use the flash when it thinks it needs more light.
12. What happens to your photo if there is too much light? the photo will not look like real life.
13. What happens to your photo if there is not enough light? the same as having to much light the photo will no look like real life.
14. What is a “stop.” To represent a relative change in the brightness of light.
15. How many stops brighter is the new planet if there are two sons instead of one? It would be 1 stop brighter.
16. How many stops brighter is the new planet if there are four sons instead of two? If the new planet had 4 suns if would be 2 stops brighter.
17. What affect does a longer shutter speed of have? More light
18. What affect does a shorter shutter speed have? Less light
19. What does the aperture control? The aperture is like a pupil. You can control the amount of light that reaches the lens.
20. When adjusting the aperture, how can you increase the amount of light? set the aperture settings at a lower level.
PART II: CAMERA PARTS
aperture- A device that controls the amount of light admitted through an opening.
shutter- A device that opens and closes to expose the film in a camera.
exposure- The amount of light that falls onto the sensor of your digital camera.
depth of field- The amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph.
F-stop- A camera setting corresponding to a particular f-number.
focal length- the diastase between the center of a lens or curved mirror and its focus.
Camera parts:
Shutter button- It has two functions one is if you of a half-press to focus the photo and the other is to do a full press to take a photo.
Flash button- This button helps you set the flash on auto of that you can choose when you want to use the flash.
