Task 2:  Impact of evolving output mediums on the design and creation of graphics images
There is an impact of developing output media on the design and creation of graphic images, for example, there is a big difference in using latest and advanced printers than using the old ones, or maybe having a big monitor over a small one. This is because, one has a high resolution in big and new printers, or monitors because it means that the quality produced will be better, as well as one has a big zooming area than would have in small resolutions. The only challenge is buying the big and developed mobile phones, printers or e-book readers may be expensive. Additionally, there have been developments in printers since they were first created, where they were very slow and basic printers. They used to be expensive at the time unlike now, where one can purchase them easily. The only problem is that such printers take a long time to print and therefore, shows how much printers have upgraded but expensive. To add to this there are new printers that have come up and made currently, as well as increases speed of printing as well as lowers costs (Niemeyer, 2008, 23-144).
Development of mobile phones also has a big effect on the design and creation of images. Latest mobile phones’ models have cameras, which can be used to take photos and transfer them to a computer using either Bluetooth technology or a data cable. In addition, some mobile phones have such as latest smart phones have inbuilt softwares that can be used to edit images. E-book readers have also had a great impact on the design and creation of images. E-books are now designed in such a way that they are compatible with both the computers and e-readers.

In addition, the figures seem confusing as they are neither titled as numbers in thousands nor are presented as the currency amount paid/received in a specified time period.
