Answer:Light is focused on to a light sensitive chemical deposited on a thin film. The light is allowed to strike the film surface for a short time by the use of a shutter. The shutter acts as a valve for the light. When light strikes the film, the light sensitive chemical undergoes a chemical change. The amount of light makes a proportional amount of change in the light sensitive material (within limits). Too much light can 'overexpose' the film, causing too much of the light sensitive 'grains' to change and not leaving enough of them unexposed to make a discernable image. After exposure, the film is chemically treated to 'develop' the image. The chemical treatment causes a permanent change in the light sensitive grains, and renders them insensitive to light. It also makes them visible.

The lens focuses the light on the film. The 'focal length' of the lens determines how large the focused image will appear on the film.

The shutter acts as a light valve. A longer exposure allows more light, and a shorter exposure allows less light.

The iris acts to reduce the amount of light, and it also affects the focus. This is called the 'field of focus'. A smaller aperture in the iris produces a larger field of focus, allowing object closer and farther away from the actual point of focus to appear sharper.

The camera's light meter measures the amount of light coming from the direction of the subject.

A computer in the camera can control the aperture, shutter, and lens focus to make the act of taking a picture completely automatic, needing little thought by the photographer. The photographer is free to concentrate on the subject.

Filters can be used to correct for differences in light source color balance, reflections off of objects, ultraviolet light, and create different artistic effects.

It all depends on the kind of digital camera you have, if the lens mount is the same on both of the cameras, then the lens will work (Minolta and Sony are interchangeable) Off camera flashes may also work, again depending on the kind of camera(s). And of course, film wont.

Any film camera with a light meter, and every digital camera, has a sensor that will do that.

I think camera work is an art form, video or film can also be considered art.

You can not convert a RollieCord TRL camera to use 35mm film instead of 120 film. This camera was designed to only work with 120mm film while shooting. However, there are models of RollieCord TRLs that do only take 35mm film too.

Instant camera uses a type of film that develops within 2-5mins within the exposure. Film camera uses film that are either slides or negatives that need to be developed in a lab.

please add more detail on type of memory card and type of Kodak camera It will probably work

The main difference between a film and digital camera is the fact that a film camera uses film. A digital camera uses a SD card instead of film.

The same as any other camera. The difference is the film or sensor, which is designed for sensitivity to infrared light.

Camera in the film will store images so that it can be developed.

It depends on the brand of camera and the type of lens. Most Nikon film SLR lenses will work (in manual mode) on their digital SLR cameras. Many Canon lenses will work on new Canon SLR cameras, but you have to check compatability between the camera model and the type of lens. Sony purhcased the Minolta digital camera division, so all Sony Alpha DSLRs will use Minolta lenses.

Depends on the type of film you are talking about. Photographic film for camera, film for cinema, film for wrapping sandwiches. Be more precise. Go to a shop and ask.

the difference is film camera needs a film to capture a picture and digital camera does not need the film to proceed. but it needs only a memory chip to save the captured pictures on it.

Sorry I don't know the answer I'm not in film school(which i heard was a waste of time) and I'm on the path to shooting a short movie. Please answer

Infrared (IR) photos are taken with normal cameras using infrared film. The difference is the film used, not the camera. IR film is sensitive to the IR spectrum of light, not the visible spectrum.

Polaroid cameras are powered by a battery located inside the film catridge. Changing the film on your camera will give it power, if that does not work, your polaroid film may be expired, or your camera might be broken. good luck!
