 The Technology Replacing Greenscreen

    Taking something from one shot and putting it on another, a problem as old as time in the film industry. Over the years 2 main techniques have developed, chroma-keying and rotoscoping, to chroma-key something you take the shot in question, and replace a single color present, all of that color, so you must be safe in not putting the color on anything you're trying to remove. To rotoscope, you have to manually cut out whatever is being removed, this works wonders in costume design and specific detail, but the detail is what makes the technique not favorable in a lot of situations, presuming the footage is at 24 frames per second, that is 24 pictures that have to be manually traced and cut, and don't forget they have to be cute well if you want them to be better than green screening. Brough to prominence during the production of the Disney original series The Mandolorian, LED display walls are giant curved screens with high fidelity and high dynamic range, the LED screens provide the best of both worlds. They allow for varied costume and set design that green screen cannot support, but the perfect edges of rotoscoping. The way they are used in the Mandolorian is that of screens that display environments and weather created in blender and other rendering engines. The technology was vital for the show because since the main character in the show where shiny reflective armor, that to sell believability to the viewer, needs to have proper reflections. The technology also provides a lot more flexibility in set design, they can put the screens around any ground set they need and replicate the environment perfectly. It also allows for quick changes in lighting, props placement, and set changes.

The Camera - Exposure Triangle

How All Three Components Work Together     From the previous blogpost I have made, I have went through and explained ISO, Shutter speed, and Aperture. All three have different ways of manipulating how light enters the camera, but combining the unique features of all three would allow for amazing results. To begin, aperture is how big or small the lense is, which allows for more or less light, with a low f-stop of 5.6, a lot of light would be flooding the lense, so with normal ISO and shutter speed, the image would be too bright. With a low f-stop, reducing the ISO would be a great choice, for it reduces grain in the image, preserving quality but allowing for proper right. On the other hand, you can increase the shutter speed, something with a speed of 1/400 of a second would allow for a still frame picture with little blur in the foreground. A typical combination is a quick shutter speed with a high ISO. This is typically used in sports photography or nature shots, for a high ...

 How I Plan To Make The Film     Doubling down on this low budget aesthetic for the film, I plan to make use of the look for comedic effect. Adobe software's such as Premiere Pro and After Effects provide many ways for any film maker to preform many effects such as title sequences, and adding computer generated imagery, but I plan to forgo that for my film. The entire project will be filmed using carboard effects, titles, costumes, everything. There are multiples way I plan to get around the lack of computer effects, below I provided a drawing of how the effects will be made in simple ways. For most projects I have made, getting releases and permission to film on a location has added unnecessary time, so for controlled lighting and an open space, I will film a majority of the movie in my garage.

Copyright Law And It's Affects on Cinema     Copyright is undeniably a good thing for the artistic world, it makes sure that creators are able to profit off their works for considerable amounts of time, but also eventually lets these works fade into public domain and enter the large collection of free and open works. That's how its supposed to work at least, but now we are entering an era of corporate owned works and creative expression, where the there's no singular person who owns the copyright, so how does this affect movies and other creative industries. Copyright was initially meant to be 28 years, so right now, if the original law was still in place, almost every Marvel hero, Superman, Star Wars, and much more would be public domain and anyone with a camera could make their own films with these characters. Over the years the copyright length has been expanded to the life of the creator plus 70 years. One thing to remember about this is that these expansions have bee...
