Some Interesting Information about the Camera
The Camera:
1) The camera obscura effect is an optical effect discovered by Greek and Chinese philosophers. It is achieved by creating a small hole in the wall in a completely dark room, and the outside scene is projected upside down on the wall. This is because the hole acted like the lens of the camera, that focuses and projects light onto the wall.
2) The invention in the 17th Century that helped man get one step closer to inventing the modern camera was the glass lens.
3) The parts of the first modern camera that was invented by Niepce are a glass lens, a dark box, and a film.
4) Modern digital cameras have a lens where light passes through into the camera, or box in the case of Niepce. That is what modern digital cameras have in common with Niepce's camera.
5) Digital cameras use an electric sensor called a CCD to capture an image.
Camera Modes:
1) The difference between the Auto Mode and the Program Mode is that Auto Mode completely controls flash and exposure, but in the Program Mode, you can control flash and a few other camera settings.
2) The Portrait Mode is used to blend out the background. It works by using the fastest available lens setting (aperture).
3) The Sports Mode is used to freeze motion. It works by using the highest shutter speed possible.
The Half Press:
1) You should do a half press on the trigger button because that allows faster camera response time, more control over focus, and it encourages better composition.
Controlling Flash:
1) The symbol below (Disabled Flash) means that there is no flash. You would use this when you want the mood of the photograph to be more dramatic.
2) The symbol to the right (Auto-Flash) means that auto-flash is determined by default. The camera will automatically fire if it thinks it needs more light.
Introduction to Exposure:
1) If there's too much light, then your photo will look washed out.
2) If there's not enough light, then your photo will look too dark.
The Universal Stop:
1) A "stop" a term used to represent a relative change in the brightness of the light.
2) If there are two suns, rather than one, the planet is 1 stop brighter.
3) If there are four suns, the planet is 2 stops brighter.
Shutter and Aperture:
1) Longer shutter speed has the effect of more light.
2) Shorter shutter speed has the effect of less light.
3) The aperture controls the amount of light that reaches the film.
4) When adjusting the aperture, you can increase the amount of light by setting the F-stops numbers to lower numbers, which creates larger openings, which in turn increases the amount of light.
