Steps of how a camera works
Transcript of Steps of how a camera works
Step 1: Prior knowledge
Step 2: Lens
Step 3: Focus
Step 4: Light
Cameras use a shutter to keep the film dark. When you are ready to take the picture the shutter opens so it can let light in so the chemical reaction can take place and the picture you want will be captured on the film. Cameras are made to let just the right amount of light in. If too much light is let in then the picture will be very white and washed out if not enough is let in then it will appear too dark. the shutter speed helps determine this This is why some cameras have a flash to help control the amount of light the camera needs for a good picture.
All steps of a camera are essential and with out one a picture could not be formed. In order for a good picture everything must be working properly and together.
Cameras are used every day with out thought of how they work. Surprisingly the process is fairly simple for a manual single-lens-reflex camera. Important components are the lens, focus and the light used which allows the chemical reactions to take place.
The optical component of the camera is the lens, a curved piece of glass or plastic. that takes the beams of light bouncing off of an object and redirect them so they come together to form an image on a film. Light travels slower through glass so the lens gives it time for the film to capture the picture. The rounder the lenses the more acute the angle will bend, Using different lenses will change your pictures and give you different focal lengths
The angle of the light beam's entry into the lens and the structure of the lens is very important to the focus, the light path depends on it. Focus is all about how close or far away an object is from the lens this is effected by the angle of light entry. Light beams that enter at a sharper angle will be larger. But the "bending angle" always stays the same. When you focus a camera you are moving it closer or further away from the film to make the picture as clear as possible. This takes knowledge of geometry because you have to know the angle from the real object to know where it will fall on the film.
