Green Screens: How Do They Work?

Green Screens How Do They Work

Most of the times, especially on science fiction movies, we see actors flying or riding dinosaurs backs. We also see them defying the laws of gravity, or standing in a place that we cannot imagine that it exists in the real world.

In addition, we also encounter dreamy scenes, magical places, and out of the world nature views. Sometimes, actors are standing in a city we have seen before, and suddenly something change; the actor himself or herself transform into a bat or whatever, and a place that we have never seen appears. Have you ever wondered how producers do that? Or how can an actress become a cat or anything else? This is what green screens are for!

Chroma Key

Green Screens How Do They Work

Which also means green screen, consists of backdrops of brightly colored fabric or paint, which is usually vivid green colored, that help induce all of this high-tech fakery. In fact, Chroma keying allows producers to separate the actors or people from the green background, and replace the background with pretty anything they want, such as sceneries, dragons, animated backgrounds, etc…

The process

Green Screens How Do They Work

The green screen is used by taking a previously recorded video, and isolates and removes a single color in a narrowly defined region of the spectrum. Usually, the color of the screen is bright green or blue due to the fact that the two colors are different from human skin tones and are not usually present in the actors’ outfit colors. Additionally, Chroma keying for live feeds requires hardware that can recognize and manipulate multiple video channels — layers defined by color — while recorded material can be changed in post-production with video- or photo-editing software.

In fact, this is the most used process in the post production of science fiction movies. We all know now how Harry Potter movies’ effects are made!

Reasons why you should be investing in a Land

Carmencitta Magazine - Reasons why you should be investing in a Land 1

In the matter of fact, a vacant land is one of the most misunderstood real estate investments in the world. Moreover, people think that buying an empty land is not a good thing because it just sits there, it gives you no income, and it is boring. However, a vacant land is able to produce some serious cash flow and it’s one of the best investments in the world because of its hands-off nature and versatility. Here are the reasons why you should be investing in a land.

You don’t need to “do” Anything to the Property.

 

Carmencitta Magazine - Reasons why you should be investing in a Land 2When you buy an empty land, you will not have to do anything to it, no construction, no renovation, and no nothing. However, you need to take into consideration on thing: is it suitable for building and construction? If the answer is yes, you will already be winning a huge amount of money, because when someone needs a land in order to buy a house or anything, you will be able to sell it and win.

An empty Land is a “Hands-Off” Investment.

 

Carmencitta Magazine - Reasons why you should be investing in a Land 3If you have already invested on a land that has a house on it, you will be able to remember: dealing with tenants, toilets, bugs, mold, lawn care, leaking roofs, bursting pipes, broken furnaces, and the hundreds of other issues that come with owning a built on land. However, an empty land will not involve ANY of those things.  Once you buy it, it sits there, and nothing happens.

Land is Very Inexpensive to Own as a Long-Term Investment.

 

This only happens when you are able to find a piece of land for the right price in order to buy. In fact, once you do so, you will be keeping mortgage payments, utility bills, the cost of property insurance, and property taxes money in your pocket. Moreover, this is a good way to help you keep your cash somewhere and forget about it.

The Fliz Bike; A bicycle with no pedals

Carmencitta Magazine - Fliz Bike

Bicycles have been the same from years ago until today. Of course, there are some aspects that have changed such as the materials used, the bike’s design, and the technology used to make it faster. Other than that, bikes remain bikes; a two wheeled vehicles with two pedals that require you to use your legs in order to be transported from a location to another.

Carmencitta Magazine - Fliz Bike 1All the things mentioned above (the bike’s design) started to become boring to engineers and designers. This is why, they tried to change a little bit, but in fact, they changed a lot! Their latest invention that had to do with “bicycles” made the go wild and remove the part that has to do with pedals, and this is where “The Fliz Bike” came from.

Moreover, we cannot know if the changes were done for the better, but we surely can know that they were made for a more entertaining cycling experience.

Carmencitta Magazine - Fliz Bike 2In fact, The Fliz, is a German word that means the whiz or dash, has totally deleted the pedals part or the bicycle, and connected the two wheels by a somewhat bridge that has a thing similar to a life jacket hanging from it where you put your body and buckle up.

In addition, The Fliz works depending on the user’s legs. He or she has to walk, and slowly start running, which makes the wheels spin faster, and in turn, take the person to the desired location.

Furthermore, The Fliz has so many benefits such as, making your body move, providing easy exercise with no probability for him or her to feel hot because, due to its use outside, and its constant movement, the air keeps on cooling his or her body.

Finally, this invention has been subject to criticism, but the thing that should be noted is that it did not come to replace the original bicycle.

What is crowd farm?

Carmencitta Magazine - What is Crowd Farm 1

MIT (Massachusetts Institute of Technology) has given two of its students the inspiration to come up with a new technology that, in the future, will be the solution to major energy problems.

Carmencitta Magazine - What is Crowd Farm 2

Tad Juscyzk and James Graham conceived, years ago, a project called “Crowd Farm”, and announced it in 2007, at the Holcim Forum awards ceremony. Moreover, Crowd Farm works by converting the movement of humans, in a crowded place, to electrical energy to be consumed later on.

The Concept

Carmencitta Magazine - What is Crowd Farm 3“The idea of a Crowd Farm would work like this: Boston’s South Station railway terminal would house a responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station’s main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current.

The electric current generated by the Crowd Farm could then be used for educational purposes, such as lighting up a sign about energy. Jusczyk stated that people should understand the direct relationship between their movement and the energy produced. A single human step can only power two 60W light bulbs for one flickering second, but a crowd in motion (Boston South station is an estimated 28,527 steps) and the result is enough energy to power a moving train for one second.” As described by them.

The Invention’s first test

Both students, decided to test the program for the first time, in the Venice Biennale, which is a train station in Torino city, Italy. They used the act of ‘sitting’ in order to generate power. In fact, the weight of the body on the train’s chair, cause a wheel to spin which in turn powers a dynamo that was able to turn on 4 LEDs.

Things you need to know before buying a house

Carmencitta MAgazine - things you should know before buying a home 1

Buying a house is a big step in the life of anyone. Especially if you are one of those people who had to work really hard for it, and not the ones whom their parents are rich to the extent that they can buy them a house. Moreover, buying a new thing, anything, can be a great investment opportunity. Here are the things that you need to know before buying a new house.

You Don’t Have to Buy a Home

Carmencitta MAgazine - things you should know before buying a home 2In many cultures, homeownership is a given, just like getting a college education, getting married, and having kids. In fact, property is one of the most reliable investments you can make. However, we noticed that, depending on where a person lives and his or her lifestyle/plans for the future, renting could be better. This is why, before you buy, look further into your situation and your plans for the future.

If You Do Buy a Home, Plan to Own It for Several Years

Of course, when we do so, we always have that thought in the back of our minds: “I can sell it or put it for rent anytime I want” however, this is not as simple as it sounds, and the act of owning a home needs thinking long-term, rather than short-term.

Buy As Much Space As You Might Need

Carmencitta-MAgazine-things-you-should-know-before-buying-a-home4When people who did not get married yet, think about buying their new home, they think about buying a small one at first, and after they get married, they buy the bigger one that is appropriate for a family. However, this might not be a good idea, because you do not want to live in a small place, and after a while get surprised by your girlfriend pregnant with twins. In fact, you can think about investing your money on a place that will fit for a family, even if you are not married. However, be careful not to buy too much space.

Carmencitta Magazine - Kids can Turn Their Phones to Microscopes 1

This one, is a great news for parents who think that their kids learn nothing when they are spending the whole day on their phones. In fact, a new system was created; A 3D-printed smartphone microscope system. Moreover, this creation allows school kids to turn their phones into microscopes in order to experiment and play games with light-seeking microbes, which makes their days spent on their phones become more intellectual, beneficial, and educational.

Features

Carmencitta Magazine - Kids can Turn Their Phones to Microscopes 2The system is called “LudusScope”, in fact, they got the name from a Latin word “ludus,” which means “play,” “game” or “elementary school.” Moreover, the device looks so similar to a usual microscope, and can be docked with a smart phone. Moreover, it has LED lights that you can control with a custom joystick. Moreover, Students use these to influence the swimming direction of Euglena microbes, which exhibit characteristics of both plants and animals because they feed like animals but photosynthesize like plants.

What is the smartphone used for?

Carmencitta Magazine - Kids can Turn Their Phones to Microscopes3The company has created a smartphone application that allows your kids to track individual microbes by tapping on them on the phone’s screen. In addition, while on the application, they can control everything due to features like scale bars, speed readings and grid overlays. In fact, those features help the users take measurements of things they see in the field of view. Additionally, the app also comes with games that let the students track microbes while they attempt to guide them around a “Pac-Man”-style maze or use them to score goals on a simulated soccer pitch.

Whose idea is it?

The brainchild of Ingmar Riedel-Kruse came up with this beautiful idea, he is an assistant professor of bioengineering at Stanford University. Moreover, he has a lab that works on developing ways in order to make bioscience education more interactive and engaging.
