Parts of a Camera
This is a list of the parts of a standard SLR (single lens reflex) camera. It is always helpful to know the technical terminology so when you read more information about photography you will better understand the material.
- Shutter Release The button you push to take the picture. It allows the shutter to open and close.
- Shutter: Consists of blades, a curtain, a plate or some other movable object. They control the amount of time light is allowed to pass through the lens to reach the film. It also covers the aperture.
- Shutter Speed Dial: The control dial for the shutter speed. For example 30 is 1/30 of a second, which is a pretty slow speed. (and you thought a second was fast!
) - Aperture: A circle shaped opening (hole) in the lens that light passes through to get to the film. It is created by an iris diaphragm that can be made smaller to let less light through or larger to let more light through to the film. This is measured in f numbers; for example f/8 or f/11. The smaller the number the larger the opening for light to pass through.
- F-Stop Ring: The control that sets the size of the aperture opening. The stops range from 2 or 4 to 22. Again 22 being the smallest opening.
- Hot Shoe: An accessory holder found on the top of most cameras that is an electrical contact. For example a flash could be inserted here and when the shutter release is triggered the flash would be fired.
- ASA Dial: Set this dial to the ASA number assigned to the film you are using. The number reflects how sensitive the film is to light or how quickly it will react to light. This is also referred to as the film speed. Anything over 200 is considered a fast speed. An ASA of 400 is a good all-around film as far as lighting (indoor/outdoor) and motion is concerned. 200 is a good outdoor (high) lighting film but not for any motion shots. 800 is best for high motion and low light since it is more reactive to light.
- Film Advance Lever: Used to advance or move over each small piece of the film after a picture has been taken. You must wind the film after each frame/photo is taken before you can take the next one (my camera will not let me take the next picture if it has not been advanced so there is no double exposure).
- Lens: Lets the light into the camera and lets the image focus on the film. These attach to the front of the camera and the f-stop ring and the focus rings are found on the lens.
- Focus Ring: Controls the focus of the image through the lens that hits the film. You can see if the image is in focus through the viewfinder.
- Viewfinder: The window you look through to see the image you are taking a picture of. SLR cameras have a mirror that reflects the image that is coming through the lens into the viewfinder. This way you see exactly the image that is going to be put on the film.
Be sure to let me know if there a part of the camera I forgot to mention or one that you would like to know more about.
