The Camera
1. The "camera obscura" effect is an optical effect that is acheived when you have a dark room and there's a small hole in one wall which acts like a lens and projects the image from the outside into the room upside down.
2. The invention of high quality glass lenses brought man-kind one step closer to creating the modern camera.
3. The first modern camera had film, a glass lens and a dark box.
4. Both modern digital cameras and the first camera have a lens that light passes through to expose the film and create a photograph.
5. Digital cameras capture images with a CCD.
Camera Modes
6. The difference between Auto mode and Program mode is that Auto mode completely controls flash, and exposure while Program mode lets you control flash and other options.
7. Portrait mode is used for portraits and it tries to blur out the background by using the fastest aperture.
8. Sports mode is used to capture fast-moving objects and it uses the highest shutter speed to do so.
The Half Press
9. You half-press the trigger button so that the camera can focus in on the subject and it has a faster full-press response.
Controlling Flash
10. That symbol means that flash is disabled and you'd use it if you don't want any flash at all, which often times is the best choice.
11. That symbol means that flash will turn on if the camera thinks it needs more lights and it's the often times the default setting.
Introduction to Exposure
12. If there's too much light in a photo, it will be washed out.
13. If there's not enough light in a photo, the photo will be too dark.
The Universal Stop
14. A stop is a relative measure of light.
15. A planet with two suns as opposed to one would be one stop brighter.
16. A planet with four suns as opposed to two would be two stops brighter.
Shutters and Aperture
17. A longer shutter speed means more light.
18. A shorter shutter speed means less light.
19. The aperture controls the amount of light.
20. You can increase the amount of light by decreasing the F-stop number.
