Unit 30, Task 8b - D2

Unit 30, Task 8b – D2
There is different types of file format that are used when saving an image. The type of file format depends on the specific image, and some images require different file formats because of the size of them. Bitmap is a file format that is used for larger images rather than smaller ones,  this is because bitmap stores every small pixel that is in the image which makes the image have good clarity, however the file size is bigger than a normal file as the size of the image.  Another file format is a GIF (Graphics interchange format). GIF is a type of Bitmap file however is mainly an animation.  The file size of the GIF’s is good as they stay at a reasonable size, this is because of the limit of colours that is allowed to be used, this allows the file to stay at a small size.  JPEG is another file format that is commonly used as it is used for pictures, taking pictures and for downloading images from the internet. When an image is saved as a JPEG the image can become pixelated when stretched which lowers the quality of the image. They go pixelated when the image is stretched to be bigger and the file can still stay small.

Compression techniques are when an image is compressed to have a lower file size. There is two different compression techniques, these include lossy compression and lossless compression. Lossy compression is when the compression of an image makes it pixelate in order to make the file smaller. This is because the file can be used more efficiently when it is at a lower size. This usually happens when video interactions, when they freeze it’s because its being compressed to make it smaller as it will run more efficiently. Lossless is when you compress the file and expect it to be the same as before. This is when the output is needed to be a better quality, this is usually used when a file is an important document such as a legal document.  However it can be adjusted for self-standard
.
Image resolution is the number of pixels that a device can handle. Different devices can handle a different amount of pixels. The pixels are captured by height and length, and then multiplied together, this shows how many pixels a device can handle. The more pixels a device can handle the more clearly the images will be, and that is important as quality is what you use these devices for. However depending on the device depends on how you can save the images. If the device can handle a lot of pixels but has hardly any memory, then you will need a memory stick, or to make some more room. As the more the pixels the larger the file size.


Colour depth also known as bit depth is the number of bits used to indicate the colour of a single pixel.  Depending on the bits depends on how defined the colour is going to be. If there is more bits then more shades of colours can be produced, this will make the quality of an image higher, as the colour will be more defined then if there was less bits. The more the colour is defined and enhanced the larger the file will become due to the more pixels that it has to use for the colour depth.
The original photo on the left top corner is the high quality version of the photo. This means that the file size is larger than the rest of them because the colour depth is higher. The more colours the picture has means the more pixels it holds, this will create a large file. These high resolution photos are usually used for big posters and other large items requiring an image.
The Picture on the top right would be used for a book as it would be easier to print because the file size is smaller because it has less colors which reduces the size.
The picture in the bottom left would be used as a picture on a website because it hasn't been blown up and the pixels would smaller which means looking at it on a smaller screen wouldn't matter, as the quality would still be good as of the size of the file.

finally the image on the bottom right hand corner would be used as a thumbnail because it is used on websites such as Google and is uploaded in a very small file size, so when clicked on the bigger pictured is to be viewed.

The on-going development on input and output devices has changed quite a lot, especially when it comes to the quality of the devices.  When it comes to vinyl cutting the new development lets the product to be weather proof, which means that if a vinyl cut out is on a vehicle it can survive through all different sorts of weather.  Also when creating an image you can print out colours which mean buying white vinyl. Previously if wanting a colour on vinyl you would have to buy the vinyl in that colour, which would have cost a lot more than just buying plain vinyl. The development in vinyl cutters has changed for the better and is easier to supply for and use compared to how it was before.

Developments have also occurred in inkjet & wide format printing for bitmap displays and posters.  When using inkjet and wide format printing it is possible to print direct to 50mm substrate. This is development as the size of printing has gotten larger and comes in useful when wanting to have a thick image. Previously the printing would not be able to cope with that size of material. This means that big images were harder to make, however now it is simpler as the technology is available for such things as bitmap displays and posters.

 
Another development is laser printers. When printing using a laser printer you can print right to the end of the page which is convenient when making products such as business cards and leaflets. They also offer duplex printing which is printing on both sides of a page at the same time, this would make things quicker in a sense. Laser printers can also handle thicker materials such as card, which makes it even more useful. However previously when printing the image would not always go to the edge of the page, there would be a little white border where the printer had not printed on.  Also the printer wouldn’t have been able to handle thicker materials, it would have just been used for paper. This is a big development for laser printers as it has more useful qualities to it and more people will end up using them because of the quality of the product that they produce.


3D printing has also developed. 3D printing is a process where three-dimensional solid objects are made from a digital model. The process has been around for a while in different industries, however the development has been the quality of the way it works. Also it was only available for specific industries, and now it is available more for people to buy and use. The first 3D printer was created in the 1980’s, however it has been excessively adapted since then.

Unit 30, Task 6 - P6

Task 6
Creating graphics is a process of sketching designs and making new images for specific things. However even though it is just making images and developing graphics there is laws that need to be followed. Some of the laws include copy right, trademarks and intellectual property. All graphic designers play by the laws because it’s easier than getting sued for creating an image.

Copy right is a legal concept that is enacted by most governments to give original creators exclusive rights to their own work. This means that if a piece of work is granted with copy right then it is illegal for others to use for advertisement or any purpose really. Copy right is the most common and well known law for products and mostly everything has copy right and cannot be used unless it is sold by the original creator of the product.  There is limitations to copy right and some exceptions are made, for example students using images on their work, if the image is not being sold or being viewed by a wide range of people than the exception will be made.  The reason that copy right is used for the creators is so that their products can support them, if other people were allow to sell the image and use it then it wouldn’t be worth anything, copy right ensures exclusiveness to a creators product.

Another legal pitfall is trademarks. Trade marks help define and for products to be recognised by a specific symbol or image. Mostly ever products in the world have specific trademarks that define the business. They are used to claim exclusive properties of products or services.  However trademarks can be a legal issue themselves, if the creator had made the trademark offensive or it shows false advertisement then they will either have to change it, or it will be banned from usage.  Using another products trademark can give you some legal trouble, this is why this law is in place and it also helps the creators be noticed for their own work.


Intellectual property is a legal concept that is granted to creators of intellectual things and gives them exclusive rights that are recognised. Most of this includes musical, literary and artistic pieces, this means the creators have exclusive rights to their creation. It is also used for discoveries that are made and inventions, in some cases it is used for creators of words and symbols, but they all connect to copy right and trademarks. This law was put in place so creators get recognition for the work that they have done.
