BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Raster Graphic Raster Graphics are graphics that show the rectangular pixels that makes that image up. These pixels are viewable from a computer monitor and paper. Each pixel holds data used in creating the image. These graphics are easier to manage than Vector Graphics. Raster Graphics are more used in photography editing. CMYK is usually used in Raster Graphics. Photoshop and Painter are used to edit pixels (Raster Graphics). This Graphic is based on cantones whereas Vector Graphics are based on line. The Raster graphics are made of pixels, http://en.wikipedia.org/wiki/Raster_graphics Is this means the image is easier to edit where I found my information on Raster Graphics. and is easier to mimic or change. http://www.google.co.uk/search?tbm=isch&hl=en&source= When you zoom into a raster image Is where I found the picture for Raster Graphic. you can analyse the different colours used to make the image.
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Vector Graphic Vector Graphics are used in lines, points, curves and shaped to make images. Vector and Bitmap/Raster work well together This is a example to make images. A mathematical of the differences Formula is used when it comes to between the two making a Vector Graphic. This graphics>. means the image can be re-sized without it being distorted or pixelated. Vector Graphics are used in 3D filming and TV as well as illustrating. Vector makes a http://www.ehow.com/how_6027909_create-vector-graph better image than Raster but not Is where I am acquiring my information from as easy to edit colour with.

Vector where I have found the image above^. also require much less memory than Bitmaps. Vector is the mathematical term for what makes up an image on a computer.
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File –Antialiasing Antialiasing is a software used to convert images with jagged stair like edges to smooth edges. The reason an image may have jagged edges is because to monitor may not have a high enough resolution to create smooth lines. Antialiasing software creates a gray outline around the image to loose its stair like appearance, but this does make the imaged fuzzy in some cases. This method is sometimes called oversampling. It is also used in video games and graphic cards. The bitmapped image http://www.webopedia.com/TERM/A/antialiasin has a jagged outline. Is where I’m gain some of my information from.

BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Resolution Resolution is the number of dots or pixels used in an image. The higher the resolution the clearer the picture/image. This refers to film and digital images. The resolution can be measured in lines per mm. The image bellow shows the different pixel resolution. Spatial Resolution is the resolution of lines. Spectral Resolution is the resolution of colour. Temporal Resolution is where high-speed cameras can change 100 frames into 1000 frames so that the image produced after is clearer. Radiometric Resolution determines how finely a system can represent or distinguish differences of intensity. http://en.wikipedia.org/wiki/Im was where I retrieved my picture and information for this slide.
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Aspect Ratio Aspect Ratio is the ratio of an image( height and width). This is used in These ratios are motion pictures it determines the physical size of the film. Television very common. and computer monitors use 4:3 and HD televisions use 16:9 (16 being the length and 9 being the height). In the 1950’s almost all the motion pictures were 1.33:1. Aspect ratios are used to determine whether a web banner can fit on a web page. In still image photography the aspect ratio is usually 4:3 or 3:2. <These are the formulas used to determine the height and width. http://www.wisegeek.com/what-is-aspect-ratio.htm Is where I retrieved my information. http://en.wikipedia.org/wiki/Aspect_ratio_(image) Is where I found some information and images.
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – File Formats File format is the information that is encoded in a computer file. Gif, Jpeg, Tiff, Eps, PSD and PDF are some of the file formats found when saving a document. There 195,112 different file formats while all depend on the different files, programs and other data. These different formats compete with each other and also perform differently. Gif- This file format stores colour graphics such as moving images. Jpeg- This file format stores digital images and compresses them. Tiff- Tiffs are a file format that stores images that have been manipulated. Eps- Eps can store text a long with an image such as logos. PSD- This file format can easily store files that have layered images. PDF- PDF was created by adobe so that their files could be portabily moved from one computer to another. http://www.answers.com/topic/file-format http://en.wikipedia.org/wiki/File_format
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Colour Model A colour model is a mathematical model describing the way colours can be represented as numbers. Televisions transmit light using the additive; red, blue and green which helps the viewer see a clearer image. The RGB model consists of red, blue and Green. The CMYK consist of cyan, magenta, yellow and black. http://en.wikipedia.org/wiki/Color_model
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Adobe Photoshop Photoshop is a programme used to edit photos and images. The default file for Photoshop is PSD. A PSD can support images that have be edited in various ways. It was created by Thomas Knoll in 1988. You are able to crop, retouch, slice and modify colour. The programme is used by many magazine companies and used a lot in advertisements such as posters and web banners. When editing a landscape photo you are able to enhance colour and shadows. The files can also be saved as JPEG, TIFF, DNG. Photoshop can also be found as an android app. Unlike most photo editing software it’s strengths are pixel based images. Using Photoshop you can change an image completely
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Adobe Illustator Illustrator is a vector graphics editor released 1987 by Adobe. Like Photoshop, Illustrator is able to edit photos but Illustrator is used in design and logo based work. It also used in web design and rastirzaion. Shapes and images can be layered on top of each other to make various designs and images. Similar to Photoshop you can layer objects such as shapes and images so make a final image. You are able to add shapes, modify colour, place text and draw using the paint brush or pencil tool. Illustrator projects can be saved as the files bellow.
BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – Adobe InDesign InDesign is a programme hat is used to make leaflets, posters, magazines and brochures. It was first released in 1999. Like all adobe software it can be exported as PDF. You are able to design and create pages for websites and tablets. You can also create projects for print such as double page spreads and book covers. The editing software on InDesign is limited compared to Illustrator and Photoshop, but where these programmes fails, InDesign succeeds. InDesign is capable of creating whole web pages, despite of it’s limited editing capabilities of images and shapes.
