Camera History and Camera Parts

1. Explain the "camera obscura" effect. How is this achieved?
Camera obscure was the first camera made, which had a hole acting like a lens, focusing and projecting light into the wall.

2. What invention during the 17th century helped man get a step closer to creating the modern camera?
During the 17th century 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 camera invented by Niepce?
He added "film" to create the first successful photograph, and the modern camera was born, he also added glass lens, dark box, and film. 

4. What do modern digital have in common with Niepce's camera?
Light passes 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?
They capture an image with an electronic sensor called CCD. Modern photography is cheaper than it has ever been before.

6. What is the difference between the auto mode and the program mode?
In auto, camera will completely control flash and exposure. Program automatic-assist, just point and shoot.

7. What is the portrait mode used for? How does it work?
To attempt to blur out the background, camera will try to use the fastest avaiable lens setting.

8. What is the sport mode used for? How does it work?
To freeze motion, camera will use the highest shutter speed possible.

9. Why should you do half press on the trigger button? 

We should half press on the trigger button because we are one step ahead to get the photo we want. 

10. What does this symbol means

This symbol means "no flash" you may use it when you're in a place when theres to many light, so you don't need the flash to help you to take a good photo.

Used en every aspect of photography 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 just one step brighter, if you have one single light bum and other bulb the light would increase

16. How many stops brighter is the new planet if there are four sons instead of two
You should have 2 stops because you're adding two more.

17. What affect does a longer shutter speed of have? 
More light

18. Wha affect does a shorter shutter speed of have?
 Less light

19. What does the aperture control?
Controls the size of the opening lens.

20. When adjusting the aperture, how can you increase the amount of light ?
By setting the "aperture opening" also known as an F-Stop
