I really like filming, do you like it at all?
Yes! I'm big into cinematography. It's an actual science and art of motion-picture photography, so it's very important to how the film gets made and how it looks. It includes things like recording light or other electromagnetic radiation, among other things.
That's awesome! Definitely, it's super complicated and it has evolved quite a bit since the early days.
Yeah, it involves things like using a lens to repeatedly focus the light reflected from objects into real images onto things like a light sensitive surface inside a camera when doing an exposure, in order to create multiple images. It's highly complex stuff.
I did not know all that, the things people are able to do with modern day cinematography is beautiful.
Yeah, and that's just part of the process. But the end result with photographic emulsion ends up being a series of invisible latent images on the film stock that's produced, and then these are taken to be chemically developed into an actual visible image. Tough work.
You're really beginning to make me appreciate all the complicated things that are able to make cinematography possible! 
It really is something to appreciate, especially because it's not just about the movie business, but it's applicable to fields of science, business, mass communication, and then, of course, entertainment. So, it's so multi-purposeful.
That's so cool! Thank you for all this information about cinematography, it piqued my interest in it all even more.
And just so you have a better idea of what the word even means, it's Greek, meaning movement and motion (kinema), and to record (graphein). Recording motion!
