Khun, Twitter, Charlie Tango discussed on The Art of Improvement Show with Giovanni
And a love all things Tech and I received a request via Twitter. And remember, you can reach out to this show by tweeting to Tech stuff. H s W And this tweet came from CTB. That is, Ah, Charlie Tango. Bravo, The message said. I was recently looking up klieg lights, and I wondered about lighting for recording TV and movies. You touched on it some in your recent green screen broadcast. Would you have a podcast about TV movie lighting? You'd get to explain Best boy and gaffer. I've actually talked about best boy and gaffer on another episode. I think I did a full episode about the different roles on a movie set, but we'll get to those again because they are relevant to this and C T. B. I absolutely will do more than one episode on this topic. It's actually going to require us to go back quite a ways to stagecraft and stage lighting to really understand how lighting has blade, a critical role in the way we present drama, comedy and various entertainment. Yes. And so this episode or Actually, episodes will be a little different from my typical episodes. I could just explain how these lights work from a technological point of view. But first that wouldn't take a terribly long time. It be pretty short and sweet, and moreover, I think it misses the more interesting point, which is how artists leverage technology to create specific effects. It's sort of like the difference between talking about how paint is made. And how a master artist Khun take that paint and create a stunning piece of art. We're going to look at not just the science but the art behind lighting with film, television or digital cameras. Lighting is absolutely critical. If you want your shot to look good, it's Only with the careful coordination of camera and lighting departments that a shot can really look great. You could have an Oscar worthy performance going on. But without good lighting. No one will be able to see it. Moreover, lighting is an important component that contributes to the overall effect A director wishes to create. Great lighting can make a scene more intimate or harsh or mysterious or scary, Precise control over lighting allows storytellers to shape a scene in a way that Khun better evoke the reaction they want out of their audiences. Great lighting can really enhance a scene and terrible lighting can take away from it. Typically, really good lighting is the type of effect most of us don't really notice. But bad lighting can be downright distracting. So there's a lot of science and art to this and there always has been. Now let us remind ourselves. Why lighting is important in the first place, which is super obvious, but we have to start somewhere. Arsons of vision is dependent upon receptors in our eyes picking up light that is reflecting off of various things. When light hits an object, one of a few things can happen or a couple or several Transparent object will allow much of the light to pass through it. And this is what we would call transmission. The object is transmitting light from one side to the other. So a pane of glass That transmits light. An object might absorb the light, in which case the light energy will convert to heat and the darker and object is the more light. It's absorbing something like Vantaa Black. That's ah, material that's made up of carbon nanotubes can absorb up to 99.96% of light. Or the object might reflect light. The light. The object reflects might be across the visible spectrum like a mirror, So you get all the visible light, or it might only reflect a bandwidth of frequencies that correspond to particular colors of light. A red ball is reflecting light that largely falls in the 4.3 times 10 to the 14th power Hertz frequency that corresponds to red light. That's just an example by manipulating light that hits a scene Whether that scene is on stage or captured in a camera. You can affect how that scene looks again that falls into common sense. But my goal is to explain Why this works, not just how it works, and we'll do this by talking a lot about history because you guys know I love to tackle topics that way and let's start with theater. I'd say that the art form of theatre grew naturally from the older art of storytelling. By the time we get to the ancient Greeks, we see cities building structures specifically to act as performance spaces. And these were all outdoors. So the lighting came from natural sources that you know, being the sun and performed in the daytime, but it didn't boil down to a simple an idea as let's build a big old space. People can sit in and watch their afternoon stories. A lot more planning went into it than that The location choice needed to take into account when performances would take place as the sun will be in different parts of the sky, depending not just on the time of day, but the season. You wouldn't want to build a theater that was designed for a late afternoon performances. If the orientation would mean that the audience is going to be squinting into the setting sun for the full performance that Wouldn't be ideal. The typical Greek theatre had a stage near the base of a hill and the slope of the hill served as the seating area for the audience with wooden or stone benches. And then they could look down upon the action of the stage. There are some studies that suggest the specific orientation of theatres took into account, not just the angle of the sunlight. But also astronomical elements because the Greeks would dedicate these theaters to specific gods in their religion, and typically, they only held performances during times of the year where they were having holidays devoted to those specific gods. The Romans followed suit, though they also made some additions such as building awnings to cover the audience so that they didn't get too hot under the sun. As for the actors, well, they had to suffer for their art. Again. The choice was usually made the layout the theater in such a way so that the sunlight could illuminate the stage while keeping the audience at least somewhat protected. But there was really no other means of controlling the light. So you're really just saying I needed to be bright enough for the audience to see what's going on. Everything else is going to be left to their imagination. During the Middle Ages. Most theatrical displays typically in the form of stuff like Miracle plays were performed outdoors. It might be at the entrance of a church or in a courtyard. A few plays were performed inside churches, which typically allowed light in through massive.
