1. The "camera obscura" effect is an optical effect and is how the camera got started. This effect works by going into a very dark room and there is a hole which is the lens which projects and focuses light of the scene onto a wall in the dark room.
2. The invention that helped the 17th century get a step closer to the creation of the modern camera was when Isaac Newton and Christian Huygens made high quality optic glass lenses.
3. The part of the first modern camera invented by Niepce was that he add film to the camera.
4. Modern digital cameras have a thing in common with Niepce's camera, light passes through the lens an then into the camera which exposes the film and Poof theres the photo you just took.
5. Instead digital cameras using old plastic film they use a digital film called CCD.
6. The difference between Auto mode and Program mode is that auto mode the camera does everything for you you just have to take the picture. In program mode the camera still does everything for you, but you can twik a few things.
7. The portrait mode is used for taking a portrait of something (hint: thats why its called "portrait" mode) . This works by the camera blurring everything in the background so it can take the picture.
8. The sports mode is used for taking pictures that are in motion and what the camera does is that it freezes the object in motion and uses the highest shutter speed to take the picture.
9. The reason you should do a half press is so you get faster camera response, encourages better composition, and theres more control over focus.
10. This symbol is the disabled flash symbol and I would use this if I was taking pictures in the daytime or well lit places.
11. This symbol is the auto flash symbol. This symbol works if there is not enough lighting where you are taking the picture so the camera puts the auto flash on.
12. If there is to much light in your photo then your picture will look washed out.
13. If there is not enough light in your photo then your picture will be too dark.
14. A "stop" are relative measurement of light.
15. There is one stop on the planet.
16. There will be two stops on the planet if there were four suns.
17.If you are using a longer shutter speed you will have more light.
18. If your are using a shorter shutter speed then you will have less light.
19. The aperture controls how much light goes through the camera or how much it will take.
20. If you have a larger opening in the aperture then you will have more light.
