The Camera Q&A

1. Explain the “camera obscura” effect. How is it achieved?
The camera obscura effect is created by a very dark room with a small hole in the wall and through that hole light is focused and then the scene is projected onto the other wall upside down.
2. What invention during the 17th Century helped man get a step closer to creating the modern camera?
Isaac Newton and Christian Huygens help to prefect the understanding optics and the process of making high quality glass lenses.
3. What were the parts of the first modern camera invented by Niepce?
Niepce added the final touch, the film, to create the first successful photograph, and thats how the modern camera was born. 
4.What do modern digital cameras have in common with Niepce’s camera?
New cameras and Niepce camera work basically the same way, not much has changed other than quality of the photo and the speed in which you can take it.
5. What do digital cameras use to capture an image?
Instead of using a plastic film we store the photos in an electronic sensor called a CCD, photos are stored on a reusable electronic memory chip.  
6. What is the difference between the Auto Mode and the Program mode?
It tells the camera heather it needs to take pictures or display them, some cameras only have on and off.
7. What is the Portrait mode used for? How does it work?
The portrait mode is used for blurring the background of a picture, it works by going to the program setting and then finding the portrait icon and then you select it and it will blur the background of a picture by trying too use the fastest available camera lens.
8. What is the Sports mode used for? (not just sports) How does it work?
The sports mode is used to freeze motion, the camera will try to use the highest shutter speed possible.
9. Why should you do a half press on the trigger button?
You press with only a little bit of pressure and wait for the focus lock and then a blincking light will start to flash saying its focusing, then the light stops and you hear a beep it means the camera is ready to take a picture.
10. What does this symbol mean?

 When would you use this?
It means no flash, you would use that when its a bright day or you want to get a shot of some ones out lines so you would have light in the back but you would use the flash on the camera.
11.What does this symbol mean?
When would you use this?
On most cameras auto flash is pre-set by default and will automatically fire if the camera thinks it needs more light.
12. What happens to your photo if there is too much light?
If you have too much light your picture will be washed out and all the colors will be lost.
13. What happens to your photo if there is not enough light?
When a picture doesn't have enough light the picture will be too dark and you won't be able to see what is in the picture.
14. What is a “stop.”
The word stop is used throughout photography to represent a relative change in the brightness of the light.
15. How many stops brighter is the new planet if there are two suns instead of one?
The new planet is 1 stop brighter then Earth.
16. How many stops brighter is the new planet if there are four suns instead of two?
The planet with 4 suns would be 2 stops brighter than Earth.
17. What affect does a longer shutter speed of have?
The shutter speed controls how fast light travels through to the film, the longer the shutter the more light goes to the film.

18. What affect does a shorter shutter speed have?
The shorter the shutter speed the less light that goes to the film which is not good, just like having too much light go to the film isn't good.

19. What does the aperture control?

It's like a pupil it lets light get into the camera so then the film gets hit with light, it does so by opening and closing an opening near true film.

20. When adjusting the aperture, how can you increase the amount of light?

Moving from one f_ to another causing the aperture to stay open lounger or shorter causing more or less light to get in to get to the film.
