D2 evaluate the impact of evolving output media on the designing and creation of graphic images.
Evaluate the impact of evolving output media on the design and creation of graphic images. You will need to research how output media products such as large flat screens, printer technologies, etc. are developing. Then evaluate them against cost, speed, usage and any other criteria you discover. (D2)
The evolving industry of output media has a large and positive impact on the design and creation of graphic images due to the simple fact that it improves the overall quality of the final product. Evolving output media such as high DPI printers and 1080p HDMI televisions make images a lot more life like and clear but this is only due to the increase in power of computer devices (PCs, laptops, phones etc )that are required to drive those displays. Modern colour laser printers, laser plotters or rapid prototype printers that can produce 3D output are all evolving output media which have had a positive impact on the design and creation of graphic images. Output media has always been one step ahead of its time due to the vast improving quality of video games being produced and the hardware needed to display them. Printers have evolved a lot, a standard printer wouldn't cost you any more than around £50 however a modern, state of the art technology printer which incorporates all of the latest features such as a fax machine, scanner, colour copier, black and white copier along with a large host of tools such as colour correction and photo like printing would cost you anywhere in the region of around £100+. these kind of printers have a huge impact on the graphics industry as people are able to print high quality pictures or even photos in the comfort of there own home for a reasonably low price. However if you were in search of an industry standard graphic printer with capabilities of print very large images at a very high quality then you would find a dramatic price increase. The option to produce to the perfect graphic image via output media is endless as long as you are willing to pay the price. If you were to invest in the best graphic printer money could buy for domestic use only then you would not reap the benefits of purchasing it, however it would be wise if you were to buy one for a professional use.
Other forms of evolving output media include technologies such as mobile phones and web pages which display static images unlike those present in video games and television. When producing images which will be uploaded to a web page, size, quality and the type of website needs to be taken into consideration. For example if they website is selling expensive goods such as jewelry then it would need to look very professional and contain high quality images. It is easy to distinguish the quality of a website, layout, design and image quality are all of high importance and would be present in a professional website. Videos and animations may also be present and are becoming a lot more common. Due to this, computer specification requirements have increased to deal with this evolution of output media.
D1 justify the following in connection with the production of graphic images to meet a client and user need: software and tools used, file format.....
Produce a report for Vizual Impact to justify how the production of your graphics images met the client and user needs. Include justification of the software and tools used, the file formats, the image resolutions and colour depths. (D1)
After the production of my microsoft banner which was to be used by the company for an event held at the birmingham NEC, I am required to create a report to justify why and how I made it.
The software I used to make the image was photoshop elements which I think was a fair choice because it features a lot of tools which help you to manipulate and create graphics, resulting in unique business ideas. Using photoshop elements meets the clients needs as it is a popular program, used often and maninly for work with graphics. Photoshop also fits the requirements as it allows me to choose different sized canvas'. To ensure I met the design specification I set my page up to look like a banner, photoshops assisted me in this by providing a size wizard. Photoshop also hosts a large number of tools and techniques which helped me to create an image which met the specification. In this graphic I used the magic wand tool, background eraser, layering technqiues and colour fill. Photoshop also has the ability to resize images without pixelating them, which allowed me to resize the keyboard so that it was in the shape of a banner. Photoshop also allowed me to alter the colour depth, as standard the colour depth is set at 72, which is a reasonably high default. I could change this however it would result in a poor quality image displaying less colours. I am aiming to achieve high colour depth to meet my design specification. Having high colour depth will be a great advantage and will result in high quality banner print outs. To meet my clients needs my banner needs to look very colourful and attractive, so having the colour depth tool implemented into the software I am using will ensure that I can do this.
Image resolution is measured in PPI which is an abbreviation for Pixels Per Inch. Printer resolution however is measured in DPI which is an abbreviation for Dots Per Inch. Images which have higher DPI values hold more data and have a high print quality.Images which are of a high quality take up more memory and require more processing power. Reszing images to make them larger can reduce print quality due to the reduction in the PPI hence the term, pixelation. I had to take both PPI and DPI into consideration when creating my banner. To ensure that I meet my clients needs I used the standard resolution setting on my image so that the print quality is at its highest. There are two main reasons why files are edited at a given resolution, one of which is the intended output device has that resolution so it’s not worth editing it at a higher resolution, or the memory/CPU of the processing device cannot handle high resolution and colour depth.
My image was initially saved as a photoshop elements image which was then uploaded directly to my blog however I later discovered that I had to change the file format to JPEG or GIF as the photoshop file was simply too large and exceeded the blogs image upload capabilities. By changing the file format to either a JPEG or a GIF I sacrificed a small reduction in image quality however I now had a smaller file which was able to be uploaded onto my blog. Keeping this clients needs in mind, the graphic was still of a high quality and was now a lot more versatile as it can be sent via email or easily uploaded to websites for example eblogger. The image could also now be opened on other computers which do not have the photoshop elements program installed.

M3 demonstrate the impact that file format, compression techniques, image resolution and colour depth have on file size and image quality.
In the screenshots provided you can see that the first image is not compressed and that the second however is. The following are all factors which help to compress a file, but at the users discretion and at the images cost. By altering a files format, for example changing a bitmap to a jpeg, can severely affect the quality of the image and if done to an extreme extent can make the image unclear and very pixilated. The resoloution of the image is lowered during the compression process and therefore can result in the image being pixilated and grainy. File compression can also be achieved by altering an images colour. By reducing the amount of colour in an image you can reduce its file size, but this reduces the quality of the image yet again. Cropping and resizing the image can save memory and can result in a not so greater loss of image quality.
The basic understanding is that the highter the quality and size of an image the larger the file size, and vice versa. The higher the resoloution and the more colour the image contains the larger the file is going to be. File formats are basically preset quality settings which detract certain qualities of an image to compensate for the amount of space in which the image is going to aquire.

M2 demonstrate the use of two advanced techniques in graphics manipulation
Firstly; i took the image when i visited Blackpool beach as you can see the original image is dull and un-interesting. To manipulate this image i initially altered the contrast and brightness of the photo drastically using Photoshop, I then grabbed each section of the image seperately, using the 'magic wand' tool i was able to select the majority of the sea and replace the original colour using the 'photo filter' tool using the 'deep blue' colour and changing the density to create different shades. Any remaining sea was then selected using the 'quick selection' tool and a different shade 'photo filter' was added and altered using the density measure to create an in-depth look mainly in the far background. To make the peaked waves stand out i defined their edges using the 'sharpen' tool and then then contrast to make them dark and stand out. To create a 'surreal' looking sky i selected each cloud individually using the 'magic wand' tool and added different shades and intensities of blues, violets and oranges through the photo filter tool. I then defined the edges of the clouds to make them stand out even more using the 'sharpen edges' tool, after this manipulation i altered the hue of the clouds using the 'hue/contrast' tool. To create final touches i selected the housing and pier line using the 'magic wand' tool and manipulated as much as possible by lowering the exposure level, lowering offset levels and highering the gamma correction on the 'exposure...' tool. I then flattened the image and altered brightness/contrast overall as a whole until i was happy with my final piece, i then lowered the image size and saved my image as a JPEG file.
M1 compare the limitations of at least two different hardware devices and two different software packages utilised for the capture, manipulation...
Paint & Photoshop.
Photoshop is a very in depth and complex graphics application with many of tools and advanced manipulation techniques at hand. The adobe suite is the industry standard for graphic manipulation and production which tells you already how advanced and professional this programme is. There are many tools that can be used in photoshop such as the alteration of hue, contrast, saturation, brightening, and lightening. There are also other very useful tools to name a few; the magic wand and the lasso tool. All of the techniques listed are professional and modern ways of graphic manipulation and production. Compared to paint it is easy to see that photoshop is utilised for advanced graphic manipulation. There are very basic features in paint such as the ability to crop and resize an image and to add text and auto shapes but other than this all other tools required to produce an advanced graphic are absent. Paint lacks tools such as layering and magnetic cropping, which amongst many are huge negative factors against this programme which is why Photoshop would be the definite application to use when in need of a professional grpahic manipulation, despite of its high price.
RAM - 512mb DDR (333mhz) vs 1gb DDR2 (667mhz)
immediately you can see there is a difference in the two stated peices of hardware. Firstly one is DDR and the other is DDR2 which basically means one is single channel memory and the other is dual channel memory, this results in faster process times and allows the system to have more applications running simutaneously. 512mb is clearly less memory that 1gb which will also affect performance as it cannot run as many applications or perhaps a single large application as efficient and fast as 1gb stick of RAM could. And lastly the speed of the RAM is different and almost double! this will obviously result in faster loading speeds and better fluency when running large programmes, perhaps a game for example. 512mb of RAM is just not enough to run a graphics programme as smooth as it would need to be, it would cause endless problems such as crashing and would often be very "laggy".
Processor - 3.2ghz pentium 4 HT (1mb L2 cache) vs Intel core 2 duo E8400 3.0ghz (6mb cache)
the limitations of the 3.2ghz p4 compared to the core 2 duo would be as follows;
1) the clock speed of the single core processor would not be able to process data as quick as the core to duo would maninly due to the fact the core 2 duo has 2 subcores allowing it to break down the data faster and more efficiently.
2) The cache comparison between the two processors would also be a large factor in limiation terms because it cannot communicate to other components as quickly therefore this could result in slower loads times, slow on screen performance and even crashing.
The 3.2ghz processor would be able to handle a graphics manipulation programme if used alongside a strong rig but would still not function as fluently or as reliable as a core 2 duo processor would.

p6 explain potential legal implications of using and editing graphical images.
Copyright protects creative or artistic works. You should only copy or use a copyrighted work with the copyright owner's permission. You can copyright various work such as, literature, drama, music, art, layouts, recordings and broadcasts. Breaching the copyright act is an illegal criminal offence. Copyright does not protect ideas for a work. However, when an idea is fixed, for example in writing, copyright automatically protects it. This means that you do not have to apply for copyright.
Some images can be copyright free which mean the image can be used by anyone for any purpose at all. The following link is an example of copyright free work, http://www.copyrightfreephotos.com/.
Gaining permission for work which is copyrighted usually involves obtaining permission from the owner before it can be used for any other purpose. This permission usually involves a payment fee to the owner before the work can be reused.
If the work is not clearly copyrighted by an owner and is not stated as copyright free it is likely that whoever published it for example the publisher of the book or website is likely the rightful owner of that work.

p5 capture existing images using a digital camera and a scanner and edit them to a given user need.
Above: You can see the top image was the original picture which I drew by hand with a pencil and paper. I then scanned this so that I could gain access to it in photoshop. I then edited the image, firstly by removing all of the pencil lines which were not needed. I then decided that one of the table legs were too long so i edited the size of this too. I then used severla layers to make the cup look like it is filled with water and used two different shades of blue to emphasise this.
Above: The above image was caputred with a digital camera. I first imported the image into photoshop where I changed the contrasts. After this I decided that the image should be in black and white so edited the contrasts again to acheieve this. I then ammended random blemishes which were noticable on the original by using the smudge tool.
