What else can I help you with?
When you expose a film in a camera the image is formed on the film and What is this image called as?
a negative
What is the function of film in a camera?
The film in a camera is what actually records the image focused on it by the lens. Film serves the same function as the sensor in your digital camera, but it does so differently. Film is coated with an emulsion made of gelatin in which are light sensitive salts of silver. When exposed to light, these silver halides as they are called become able to be developed chemically into an image which faithfully records the lights and darks of the original scene. The sensor in your digital camera does the same, except that it doesn't require chemical development to view the image.
Does camera lenses have long or short focal points?
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
Why does a camera produce an upside-down image?
Because the pin hole or convex lens of the camera inverts the image being photographed. A ray of light angled downwards will be registered at the base of the film. A ray angled upwards will be registered at the top of the film. Thus inverting the image. It is easier to picture if you draw a ray diagram. Please see the attached link.
Do camera obscuras produce negatives or positives of an image?
The camera obscura is the name for a room that produces images on one wall by using a small hole in the opposite wall. Light passes through the hole and creates an image of the outside of the room. Where there is more light outside, a brighter image will be created on the inside. Therefore, the image wil be a positive one. This is the case for all cameras. The image created is always positive. However, in the case of a camera that uses film, the chemical process generates an image on the film that is dark where more light has hit the film and light where less light has hit the film. It is the chemical process that produces the negative image and not the camera itself. All cameras, including a camera obscura, will produce an inverted and reflected image, so that the image is upside down and back to front. The reason is that light travels in straight lines. It is easy to simulate this by drawing several straight lines through a small aperture. You will see that a beam of light coming from one side of the object will end up on the other side of the image.
What are the properties of an image focus on the film in a camera?
The image is inverted and smaller than the object.
What part of the eye is like the emulsion of a camera?
The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.
What is a instrument that use lenses to focus light and film to record an image?
A camera is an instrument that uses lenses to focus light onto film or a digital sensor to record an image. The lenses adjust to allow different amounts of light to reach the image sensor or film plane, creating a focused photograph.

Which device uses lenses to focus light rays and record an image of an object on photographic film?
A camera uses lenses to focus light rays and record an image of an object on photographic film. The lens helps to manipulate light rays to create a clear and focused image on the film, capturing the details and colors of the object being photographed.

What part of the eye works similar to the shutter of a camera?
The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.
What is a conventional film camera?
Its a camera that uses film. Like a digital camera has a memory card. a conventional camera uses the film which you then have to get printed before you can see the image.
How does a camera look?
It has a shutter that opens and closes on film that is an image.
Is the image formed on a camera film real or virtual?
Real!
What does a emulsion do on a camera?
The emulsion is the coating on a film in which the image is formed.
