"The Camera"
- The camera obscura effect is achieved by a hole acting like a lens, it then focuses and projects light on the wall of the dark room.
- During the 17th century Issac Newton and Christian Hugyens perfected the understanding of optics and process of making high quality glass lenses.
- The first modern camera included film, a glass lens, and a dark box.
- Modern digital cameras still work the same way as the original camera, because light passes through the lens and exposes the film.
- Digital cameras use an electronic censor called a CCD to capture images.
- The difference between auto mode and program mode is that auto mode will completely control flash and exposure. While program mode simply allows you to point and shoot, still allowing you to adjust the flash and exposure.
- Portrait mode is used when you want to attempt to blur out the background. The camera will use the fastest available lens setting.
- The sports mode is used for freezing motion, and the camera will use the fastest shutter speed available.
- You should do a half press because it has a faster response time and more control over focus, it also has better composition.
- This symbol means disabled flash. This means when you want no flash because you may just want natural lighting.
- This symbol is auto flash and you would use this when you want a default setting. The camera will automatically adjust the lighting if it think it needs it.
- If your photo has too much light then the picture will be washed out.
- If your photo does not have enough light then the picture will be too dark.
- A stop is a relative measurement of light.
- It would be 1 one stop brighter if there were two sons.
- It would be 4 stops brighter if there were 4 sons.
- A longer shutter speed means you will have more light
- A shorter shutter speed means you will have less light
- The aperture controls the amount of light that gets into the camera.
- By having larger openings you can increase the amount of light that goes in.
