The History of The Camera
The Camera Obscura Effect- Greek and Chinese philosophers discovered a weird optical effect by creating a tiny hole in a wall of a completely dark room. Light was focused through the hole and the image was upside down on the other side. This came to be called the Camera Obscura Effect.
During the 17th century, Sir Isaac Newton and Christian Huygens began to understand the physics of optics and creating high quality glass lenses, which brought man's understanding of the camera one step closer.
The first modern camera was modified by Joseph Niecephore Niepce by adding a special 'film' to the camera. Thus, the modern camera was brought to light.
Digital cameras still work the same way as their ancestors. Light passes through the lens and exposes the film. The result is a nice, pretty picture. The only difference between the two is the film. While old cameras use film tape, new ones use digital film, which is now in a little film card. The card is able to store pictures and memory.
Camera Modes
For the most recent cameras, people have been able to develop different modes for different devices. For instance, the most basic modes are the on/off buttons, the record/play, and the picture button.
Auto and program are one of the basics. For the beginners, they only have to aim and press the button. They will almost always be guaranteed a good shot.
The portrait button is for when photographers want to get a picture of a person. To use it, the person must be still. Portrait blurs out the background and focuses on the subject themselves.
For action shots, one must look no further than to the sports button of the camera. This will use the camera's highest shutter speed. It freezes the subject's movement and allows as little blurring as possible.
Half Press is the button to let the camera know that you're almost ready to take a shot. Pressing it will focus the camera on whatever the lens is pointing at. If you push it too quickly, the shot may be blurry and out of focus.
Controlling flash is for when you do not want flash. Be sure to have the flash off in museums, wildlife shots, or during the day.
Auto Flash is when you do want flash. It should be used in night shots or dark rooms.
If you have too much exposure, or light, in your area, the picture will be washed out. Too little exposure will be too dark.
A 'stop' represents a change in the amount of light. If there are two suns instead of one, there would be a one full stop. Four suns, there would be a two stop change.
There must be light in order for a picture to be fully developed. In order for this to happen, there must be a certain amount of shutter time. Longer shutter time equals more light. Less shutter time equals less light. Light passes through an opening called an aperture. It controls the amount of light that is let in through the lens. Making an f stop smaller is letting more light in and the other way around.
