I wish I would've taken a cinematography class in college. I would love to learn more about the art.
Cinematography is really fascinating! The word comes from two Greek words, "kinema" and "graphein".
Interesting! How does it work?
Well, there are actually two types. Electronically or by using an image sensor, which uses film. Which would you like to hear about?
I'm really into movies and film.
I like traditional film based cinematography too! It's an intricate process where a series of invisible latent images are captured on film stock, then later are chemically developed into a visible image. 
That's so interesting. Do you know who came up with the process?
Hmmm. I'm not sure about that, but cinematography has changed the world! Not only in the entertainment industry but in the fields of business and science as well! 
I didn't know that it was used in other fields. How is cinematography used in business?
I'm guessing because businesses are able to use film to show consumers their product in a way that wasn't possible before film. Short films can be traced back to 1895, but I don't know how businesses showcased their products before its existence.
