Creation Of Digital Images

Using Hardware And Software

Graphics Card (Hardware)

A graphics processing unit is a programmable logic chip that has the ability to render images, animations and videos that is then being able to be seen on the computer’s screen. The GPUs are located on the plug-in cards, in a chipset on the motherboard or in the same chip set as the CPU.

RAM (Hardware)

Random-access-memory (RAM) is one form of computer data storage. RAM device allows data to be accessed in the same amount of time as the physical location of the data inside of the memory.


The RAM is able to transfer data (digital graphics) to the graphics cards memory. Allowing for less of a load on the CPU .

CPU (Hardware)

A central processing unit is the electronic circuitry within a computer that performs instructions that are given by a computer program, this is done as the CPU follows a basic arithmetic, logical, control and input/output operations that are provided by the instructions.


The CPU will allow you to have multiple programs open at once so in terms of digital graphics for example of an image that is going on a website. You will be able have the editing software open as well as the website so therefor able to see the end result on the website instantly.

Digital Camera Drivers (Hardware)

Hard Drive (Hardware):

A hard disk drive (HDD) is a data storage type that is used for storing and retrieving digital information this is done by using one or more rigid rapidly rotating disk that has been coated in a magnetic material. The platter are paired with magnetic heads that are arranged on a moving arm, this then reads and writes data and sends it to the platter surface. Data is accessed in a random access manner, this means that the data can be stored and retrieved in any order so that an HDD can store data when powered off.


This will store all of the digital images/data that you have complete and or working on at the current time.



Flash Cards (Hardware):

A flash card is a storage device that is used to store digital data. They are used in the majority of electronic items, such as: phones, cameras, laptops and many more devices.


A photographer will use one of these as they will be taking images on their camera and will want to see what it looks on a larger screen than the cameras interface, so all they will need to do is plug the flash card into their laptop and they are able to see the images that they just took.


USB Storage Device (Hardware):

USB cable can be used to connect pretty much every device to your computer. This can include items such as flash memory sticks, internet modems and digital cameras. But is mainly used for your peripherals such as keyboards and mice. As well USB have the capability to charge your devices such as your mobile phone or tablet as well as allowing that device to transfer its data to your computer. The latest version of USB that is 3.0 can handle up to 5 gigabits per second (gbps) that is over ten times as fast as USB 2.0.


An example for a use of a USB would be a graphics designer who is working on a project at home might need to take it to work and continue it their. So what they would to is put all of the project files onto the USB and then place the USB into the computer at work and resume from where they left off.

Input Devices (Hardware) [Link To Graphics]

Graphics Tablet (Hardware):

A graphics tablet is an input device that you connect to your computer/laptop. Some features that come with a graphics tablet are: pressure sensitive pad that allows the creator to draw on, a special stylus that is essentially a pen/pencil however when moves over the pressure sensitive pad it will guide the mouse/pointer on the laptop/computer to mask you current movements.


These are not essential however they are a huge help to digital image creators as they are able to create more realistic images/edits to images without spending hours doing it with a mouse and still won't end up getting the same results.


Mouse (Hardware):

A mouse is a hand operated electronic device that controls the cursor that is on you computer monitor. It does this by locating the coordinates of your mouse and then displaying these co-ordinates via your cursor on the screen so the both pair up. As you move your mouse around you will be able to see your cursor moving corresponding to where you moved the mouse. The higher quality the mouse is, the more precise it will be when editing digital images.


Digital Camera (Hardware):

A digital camera is a camera that can take digital images that can be stored in a computer and displayed on the screen. This is useful for someone who works with digital images as they are able to take photos with their camera and then view or show them to others once the pictures have been places onto the computer. This is good as they would be able to showcase their pictures for sale or receive feedback on them.

Software Packages (Software)

Photo Manipulation:

Photoshop is an example of a photo manipulation software. The meaning of photo manipulation is that you are able to edit/change an image and or existing one. This would be useful for someone working with digital images as for example they took a photo of the sky in the day time and it was blue. They would then be able to change the colour of the sky in Photoshop to any colour they chose.


Vector:

Vector based software use mathematical equations and commands to create and edit graphical images. An example of a vector based software would be DrawIt, this would be used to create a logo or branded product that would be used on many different products. For example a logo, as this would be able to be placed on a shirt then again on a billboard without getting blown out of proportion and looking distort.


Raster:

Raster software is used to edit and manipulate individual pixels within the graphics. An example of this software would be GIMP. The editor would be able to change the colour of each individual pixel if they wanted to. As well as superimposing images, changing the colour on the images and many other image effects. This is great for someone who works with digital images as it gives them complete freedom to change and do whatever they like with that image.
