File format

File format allows you to save various file types with data. Some files are larger than other files and this tend to affect the quality of some of the files. Video files will be larger than documents. Therefore there is a difference in size and the formats will be saved differently. Some of the types of files include .wmv – which is for low quality windows media player videos. Another would be.ppt for PowerPoint files and .raw for unaltered video frames. The higher the quality of the files, the larger the file size will be.

Compression techniques.

There are two types of image compression. Lossy compression is one of them. It has the smallest file size therefore it can cause unwanted distortions in the image. The other type of compression is lossless compression which is the opposite of lossy compression. This has a larger file size and gives a better quality of the image. Lossy image compression techniques could include reducing the colour space to the most common colours in the image. Lossless compression might include entropy encoding or deflation.

Image resolution.

The higher the image resolution is, then the better the quality of the image. Better image resolution does mean an increased file size however this might be unsuitable for websites. For example, with Photoshop files as soon as you export an image you can select the quality of the image from 1-12. The higher number means a larger fie size.

Colour depth.

The greater the colour depth, the more pixels are used to represent the colour of an image in a bitmap image. The average levels of colour depth range from 8-bit to 48-bit. The greater the colour depth, the better the quality of the image’s colour and the definition of the image but the file size would once again be larger due to the complexity of the file.

Unit 30: Task six

There are many legal issues when it comes to graphic design. One of the biggest issues is copyright. This is an issue because there are several logo’s available for various companies which they practically own – in other words they are copyrighted. Therefore if there are any similarities to this logo, made by another organisation then they could be at risk of a lawsuit.

It is however possible to get permission to use various copyrighted logos for commercial purposes. For example these purposes could be for a film or for purposes of parody, however the process is time consuming and complicated with an uncertain outcome. Also, depending on how big the company that owns the logo is, they could demand a high price for the use of it.

Another issue is intellectual property laws. If a product from a company is found to violate another person or company’s intellectual property, they would be at risk of a large fine or possibly even a class action lawsuit if the recipient has made a significant sum of money from the theft of intellectual property.

Another issue would be the problem of obscene publications. Any graphics that could be found to be offensive to anyone; whether it be because of religion, violent, sexual content etc. without the appropriate disclaimers and warnings could be the recipient of a lawsuit or a fine.
