i am obsessed with filming.
[{"role": "system", "content": "Cinematography (also called \"Direction of Photography\") is the science or art of motion-picture photography by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as film stock. Typically, a lens is used to repeatedly focus the light reflected from objects into real images on the light-sensitive surface inside a camera during a questioned exposure, creating multiple images. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a video file for subsequent display or processing. The result with photographic emulsion is a series of invisible latent images on the film stock, which are later chemically \"developed\" into a visible image. The images on the film stock are played back at a rapid speed and projected onto a screen, creating the illusion of motion. Cinematography finds uses in many fields of science and business as well as for entertainment purposes and mass communication. The word \"cinematography\" was created from the Greek words (\"kinema\"), meaning \"movement, motion\" and (\"graphein\") meaning \"to record\", together meaning \"recording motion.\"\n"}, {"role": "user", "content": "Do you like cinematography? I once shot a home movie with my friends. It was not very well acted but we had a lot of fun doing it!"}, {"role": "assistant", "content": "How did you do that.

I never worked with real film before. I am not very technically gifted!"}, {"role": "assistant", "content": "Why not get yourself on. It is just an  electronic device originally combining a video camera and a videocassette recorder. I am sure it is not difficult to operate"}, {"role": "user", "content": "It does interest me. I know people really like using 8 millimeter film to record movies. I guess I could try it sometime."}, {"role": "assistant", "content": "We are grateful for the digital world. Now everything is digital including the camcorder. We do not have to use tape any more but storage media such as mini-HD, microDVD, internal flash memory and SD cards."}, {"role": "user", "content": "That is true, but many film enthusiasts prefer film over digital. Apparently the two different mediums give a different appearance on the big screen."}, {"role": "assistant", "content": "I never think the film is better over digital. Although film had served us in the past as it moves from a novelty to an established mass entertainment industry."}, {"role": "user", "content": "Yes there is no doubt we would not have such a big movie industry today if we never had film."}, {"role": "assistant", "content": "You are right and that is why  film production companies were established all over the world."}]
