The Marvel of 4K Resolution Cameras



What is a 4K camera
4K resolution describes devices and content of horizontal resolution of over 4000 pixels. Industry-standards 4K resolution stands at 4096 x 2160 pixels with an aspect ratio if 1.9:1. A 4K camera is one that is capable of capturing both images and video of very high detail, at a minimum resolution of 3840 x 2160 pixels. It can record videos at the same resolution and capture still images at even higher resolutions of 5K, 5120 x 2700 pixels. The Red Scarlet-X video production camera is one such device with such resolutions. Apart from the 4K feature, these cameras do not differ greatly from their high definition (HD) predecessors. They are almost similar in design, build, size, features, and user settings. 

How it works
To achieve these extremely high resolutions, manufacturers have the designed 4K camera with advanced technology capable of shrinking pixels, as well as equipping them with powerful processors that are able to render these resolutions seamlessly. Some 4K cameras may have more than one processor, and this is to ensure the video recording experience is smooth and flawless. One of the notable positives of shooting videos with these cameras is that when they capture native 4K videos, the same can be viewed on ultra-high-definition (UHD) TVs or 4K monitors with no pixel distortion.

Strengths and Drawbacks
High resolution video is not enough to set a 4K camera apart from the rest. Alongside this capability, they also pack additional features that support both video and images, in order to maximize on the high resolutions that the cameras have to offer. Such features include significantly powerful ISO settings, both high and low, to work with different lighting conditions, large format image sensors, and a wide array of both auto and manual focus controls. One shortcoming, however, is that many of these cameras cannot record 4K resolutions internally. They require additional external recorders to achieve the same. This may lead to an increase in the costs of acquiring the camera and additional accessories, as well as making the camera rig more complex when the accessories are added. 

The price of the cameras varies depending on the brand and user needs. However, if one opts for the full scale camera to shoot 4K videos, then the price of the camera and additional accessories may be well over $10,000. There are also some hybrid cameras such as the Canon EOS 1D-C, which costs up to $10,000 dollars. Smaller camcorders and DSLR cameras capable of achieving the same 4K resolutions cost anywhere between $2000-$4000. The choice of purchasing either of the two categories of cameras may depend on the intended use and budget. The Sony FDR-AX100 and the Panasonic GH4 camcorders are a cheaper 4K option for non-professional video shooting.

What you should know about Computer Programming

Every software program found on your computer was actually made by one or more computer programmers who use a specific computer language that basically instructs the computer what to do next. Computer programming is a complex topic which covers various types of programming languages which help solve different kinds of problems on your computer.

How Programming Languages Work?

Every software application in the computer, as well as video games, is made up various codes that are inputted into a program through a compiler. This compiler basically instructs the computer about how to correctly interpret those codes and what to do with them. These compiled codes will then be converted from text files into a file that the computer can actually execute. Programmers will then test run the file and see whether it works well. In the event that there are malfunctions, they will then make some revisions on the codes. For example, this tool makes programmers live so much easier.

Types of Computer Programming Languages

  • Declarative Languages

The simplest type of computer programming language is the declarative language. They basically define the function of the program without having to worry about its memory and flow.

  • Functional Languages

This type of programming language does not manipulate and change variables. They basically work on those that are constant or that never changes.

  • Imperative Languages
What you should know about Computer Programming

Unlike functional languages, imperative languages allow for the manipulation and changing of the variables of the program.

  • Object-Oriented Languages

The most complicated type of programming language is probably the object-oriented language. This is mainly because it creates functional objects that as various characteristics and variables to allow them to interact with each other for the execution of the program itself.

  • Markup Languages

Understanding Function in Programming

Before we go deep in our discussion on function in programming, let us start with the basic. What is function? Also called ‘operation’ or ‘command’, function is defined as a named block of code that accomplishes a particular task. Usually, functions receive data, calculate them, and give back results. There are functions that can return results to the requesting program without any help, whereas there are those that need to make requests of the operating system for them to work. We call this language statement that requests the function a ‘function call’.

Identifying Parts of a Function

There are four parts of a function:

1. Name – usually a word or a phrase, the name characterizes the purpose of the function (for example, "divide").

2. Inputs – inputs are called parameters. They define the data necessary in order for the function to perform its task.

3. Calculation – this differs for every function.

4. Output – this is the value computed inside the function and returned.

Writing a Function

Most programming languages have prewritten set of functions, which they keep in a library. But it is also possible to write your own functions to do specific tasks. For instance, a function may be written to get the quotient of two supplied numbers. The moment a function is written, it can be repeatedly used without the need to rewrite it. This is one of the reasons for writing functions. In writing a function:

1. Know the function’s purpose.

2. In the form of parameters, define the data that comes into the function from the caller.

3. Define the data variables that are needed inside the function for it to work.

4. Design the steps to be used by the program to accomplish its goal.

Using the Function

In programming, the act of using the function is phrased ‘calling the function’. When a function is ‘called’, the program leaves the present section of code and starts to carry out the first line inside the function. Here is how it does it:

1. The program approaches a line of code with a ‘function call’.

Understanding Function in Programming

2. The program gets inside the function and begins at the first line.

3. The instructions inside the function are carried out.

Understanding Function in Programming

4. The program leaves the function and returns to its starting point.

5. The data calculated and returned by the function are then used in place of the function in the original line of code.

All the time we see functions in programming languages and spreadsheets. There may have been a singular time we wondered what these functions do and how they do what they do. Well, hopefully, this helped a little in understanding what these so-called functions in programming are.

Systems Programming

Systems programming is the computer programming system’s activity and it is different from application programming. The aim of systems programming is to produce a software that provides services for the computer hardware such as disk defragmenter while application programming produces software that can provide services to various users like the word processor. Systems programming needs greater hardware awareness than application programming.

The characteristics of the systems programming are the following:

Systems Programming
  • The programmer will create assumptions of the hardware and all other properties of the program’s system and often, they will exploit these properties through the use of an algorithm. This is an efficient way when used together with a specific hardware.
  • Usually, a programming language or low-level programming dialect is used that:
    • can operate in environments that are resource-constrained
    • is very efficient and has minimal runtime overhead
    • small runtime library or has nothing at all
    • allows for raw and direct control over flow and memory access
    • allows the programmer to write the program directly in the assembly language
    • cannot run in the debugger, to minimize the problem, the program can be run in a simulated environment.
    Systems Programming

Systems programming greatly differs from application programming and programmers specialize in either of the two. Often, there is a limited availability of programming facilities. Also, automatic garbage collection is uncommon and sometimes it is hard to make a debugging.

In addition, if there is an available runtime library, it is far less powerful and it has lesser capabilities to check errors. With these limitations, logging and monitoring are always used and the operating systems’ logging subsystems are extremely elaborated.

Systems Programming

In the implementation of the networking and operating systems’ specific parts, they require systems programming. Examples are the implementation of a device driver or virtual memory for the operating system.

This is how systems programming works and its difference from application programming.

Now you have an idea about programming languages and how important they are in the world of technological advancements.

Programming Application

If you are new in programming application, you might ask yourself: How to start the development of an application? First, you must devise an initial idea for the application and turn the idea into a reality through the creation of an action plan to implement your app. From the design perspective, you have to develop high-level decisions on how to implement your ideas. Also, you need to set up an initial Xcode project so that the development process will be easier.

Programming Application

If you are still a novice in the development of an application, spend more time to familiarize the basic concepts. To help and guide you, there are many tutorials on the internet, they will help you to write codes. Remember, taking an extra time to learn the patterns will greatly help you as you progress.

There are various ways to program or design an application and most of the best ways do not involve any code writing. A great application begins with one great idea, it will progress as you expand it into becoming a full-featured product. In the early phase of development, it will help you create your own identity and how will it turn out just the way you planned it to become. List down the high-level features of the application so that they can be integrated in the implementation process. Also, prioritize the features that you think the users need most, to do this, do a research of the operating system to understand the capabilities and how you can use them in achieving your goals. Do not forget to sketch some of your rough interface designs on a piece of paper to visualize the look of your app.

Programming Application

Keep in mind that the goal of the first design must answer various important questions about the app. The rough design and set of features of your interface will help you realize on the requirements needed when you begin to write the codes. In other cases, you have to translate the app’s displayed information into data objects. This goes the same in the development of the app’s look. Doing the initial design on a piece of paper than on the computer will give you more freedom to look for answers beyond the easiest things to do.

To create a programming application, you must start by reading the human interface guidelines to give you a complete idea of the various strategies to make your initial design effective and useful. Also, it offers guidance and tips about the creation of apps that works well.
