Unit 35 - Undertake Technical Adjustment of Images

When changing an image in Photoshop and Inkscape you have to make some technical adjustments to the image by size, adding layers etc, adding layers to an image makes the image stand out a lot more than without, as you can add drop shadows etc which makes the image pop out and look realistic and not just like a stuck on image as shown in the image to the right adding a drop shadow to the bounce brackets makes it look like the text is bouncing around and it pops out the page, this was a good effect as it makes things look more realistic and alive,  adding filters to layers make the image your own and adds an effect such as stained glass etc, this will make the image so much different.


For example what I did here for my Facebook link for my Portfolio, I made this into a rollover image which means when you put your curser over it, it changed the look into the filter Facebook icon, this give the people who were viewing my portfolio direction, it let them know that it was a link that they could click on, the filter I used here was Artistic Cutout, it created this watercolour effect on the icon which changes the page significantly as seen, the edges are more softer than the original as such.




Colour theory is an important thing in graphic design, as graphic designers use computers mostly everyday of their job, they see RGB which stands for red, green,blue the name comes from the primary colours  as these coloured lights are adding together in a way that creates more rays of colour within the computer monitor, but the colours on a certain image on the monitor will look different when printed as it doesn't have the same light when printed this is where CMYK comes into it, when the RGB colours are mixed together they create CMYK which consists of Cyan, Magenta,  Yellow and the K stands for key which is Black, when printing your work to the human eye we see a final picture but on paper the image that is creating is made out of small dots which combine into an final image.
Any work created in RGB should be changed to CMYK format before printing unless specified, it is a good thing for designers to use swatches as it provides them with an exact match of what it will look like on printed paper.

Keeping an images dimensions is important , as if you stretch the image you will make the image all pixelated, and will be a poor quality image, the image quality depends on the size of your monitor, this will have an impact as the size on the monitor might not be the print size. When the dimensions box is checked, any changes I make to the images width or height will not change the image’s resolution and any changes I make to the resolution will not effect the width and height, Keep in mind, when I increase the width and height, or resolution, with the dimensions  box checked, I am adding extra pixels to the image. The pixels don't actually exist to Photoshop has to make them so that the quality of the image stays.


The best software to use for editing images is Adobe Photoshop, it has much better tools than others, and lets you create using loads of layers and filters this is nice to have as it has more options to do more things with an image you can change the colour to grayscale, change the size of an image, and other tools to help you create an interesting image. Many photographers use Photoshop to edit there photographs, making people have airbrushed skin etc like in magazines. A good site to retrieve images, brushes is DeviantART, which gives you images etc to create anything, some you can use for free and have no real copyright on them however some do so you have to ask the permission of the person who owns it, however when doing a logo for client or flyer they will send you relevant information and images for you to use and play around with. Importing images into Adobe Photoshop is simple, just go to file then open and choose the file you would like imported into the software, then this gives you the tools to edit the image to whatever you like.


For images different file formats they have to be used for certain images,  file formats consist of , JPEG, PNG, TIFF, RAW, GIF, BMP, JFIF etc. These are used for different images the most common ones that I use at work are...


JPEG/JFIF - ( Joint Photographic Experts Group) it is a compression method, JPeg compressed images are normally stored in JFIF (JPEG File Interchange Format) NEarly every digital camera can store JPEG's as it stores an 8 bits per colour (red,blue, green) for a 24 bit total producing small files.
PNG - This twitter icon is a PNG image, it has no apparent background to it so it can be stuck anywhere without having a white box surrounding it, PNG's excel when it comes down to image editing  and when the image has a large coloured areas around.  


With this logo I had to adapt to the colour requirement that the client wanted, they wanted no orange, blue or pink so i had to adapt the logo to meet the standards they wanted, they wanted it to be a colour that could represent both girl and boy while trying to make it look similar to what the company is all about.






In the creative and digital media sector there is health and safety regulations that need to be followed which effect this sector, such as maintenance of the workplace, equipment, devices and systems, this is key in the creative media sector as such as computers, computers are an essential piece of equipment needed in the creative media sector, computer screens can damage your eyes if looked at for too long, making sure that employees take breaks is a good way to prevent any eye strain that might occur to employee's.
Not putting chairs in front of fire escapes is essential, you must always keep a fire escape clear for emergency use and reduce the risk of others at the workplace and making sure work stations are clean and tidy, as in creative media sector wires from computers and other equipment must be tucked away out of site as this could cause serious harm to someone, to prevent this make sure any wires are hidden or placed somewhere where none could trip and fall on them.


When creating anything designers have to think about copyright, copyright is a legal concept what the government have put in place so that the person who owns that image/work has full rights to their work,  or has full credit to their work, for example a photographer has full rights to any photo they have taken unless they are employed by a company the photos are taken for or if their is an agreement that gives copyright to another party. If you want to use a photograph you would you have to contact the person themselves and ask for permission to use their photograph for example for my music that rocks website, the photographs of the bands I put on I would have to contact say Nickelback directly and ask permission to use a photograph of them however they could refuse with no permission for any reason if you don't ask for permission you could end up with a law suit on your hands.


Performers and people who are featured in your photograph etc have moral rights which protects the personality and reputation of the person, they can chose weather to be identified or not, if they do not want to feature in your photograph you will have to replace them with someone else or use a blur effect on their face so their identity is hidden.
