How is it achieved?The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber. 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? 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?A glass lens, a dark box, and 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. The end result is still a photograph.

5. What do digital cameras use to capture an image? Electronic sensor called a CCD.

6. What is the difference between the Auto Mode and the Program mode? The difference is that you can control like the flash and other simple thing. unlike auto mode with the camera controls everything.

7. What is the Portrait mode used for? How does it work? to zone out the background and it will choose the fastest lens setting.

14. What is a “stop.” is used in 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? 1

16. How many stops brighter is the new planet if there are four sons instead of two? 2

17. What affect does a longer shutter speed of have?  it gives it more light

18. What affect does a shorter shutter speed have? it gives it 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 an F-Stop.

20. When adjusting the aperture, how can you increase the amount of light? with the F-Stop
