i like photography.
[{"role": "system", "content": "Photography is the science, art, application and practice of creating durable images 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 photographic film. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically \"developed\" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing. Photography is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.\n"}, {"role": "assistant", "content": "One of my favorite hobbies is photography!

Science, manufacturing and business all incorporate photography into their work in some way.

Digital cameras today have an image sensor which produces an electrical charge at each pixel, which is processed and stored in a digital image file!"}, {"role": "user", "content": "Maybe but are skilled in the technical part of photography, I don't know anything about it. I;ve never have one of those real cameras."}, {"role": "assistant", "content": "It's technologically complex, but very easy once you understand the concept. Photography is the practice of recording light. I've always thought that was a really cool way to think about photos."}, {"role": "user", "content": "Very interesting,  I enjoy photography exhibitions and books too, do you?"}, {"role": "assistant", "content": "I do! I really enjoy old-school, black and white film photography exhibits. Sometimes black and white images can convey so much more emotion than color."}, {"role": "user", "content": "I agree but I don't know what the reason is, maybe because they seem nostalgic, or because they allow you to focus on the image without been distracted by color."}]
