  2. 2. BTec Level 3Extended Diploma in Creative Media Production HA1 - Technical File – RASTA AND VECTOR IMAGES RASTA IMAGES- a rasta graphics image, is a an representing a generally shaped grid of minor pixels and points of colour viewable on sheet via screen etc. Raster images are stored in files with varying formats such as jpeg pdf etc. Raster images is made by digital image capture devices/digital scanners or digital cameras, or by pixel editing programs. Raster images are composed of a matrix grid of digital picture elements. Pixels are squares or rectangles described as black, white, gray or RGB. Raster images typically are saved as TIFF format, but can be saved as EPS as well. Vector images exchange. Vector graphics typically are saved as EPS format. typically are generated using drawing or illustration programs Adobe Illustrator and are composed of mathematically-defined geometric shapes lines objects and fills. Since vectors entail both magnitude and direction vector elements are comprised of line segments whose length represents magnitude and whose orientation in space represents direction Look at the picture difference when in zoom.

  4. 4. AntialiasingAntialiasing is a technique in computergraphics where you can smooth Imagesthat have unfinished smudges at the endof it image so this software Techniquewould make the appearance of the imagea whole lot better. EXAMPLES:
  5. 5. Resolution Low resolutionResolution image is used for a pixel countin digital imaging. Resolution is a very importantIn the media industry of photography becauseWhat it basically means is of every picture youHave taken it always be measured on length andHeight basically the meaning of resolution isLength and height measurements of the image. High resolution
  6. 6. Aspect ratio: You can easily tell what it means by looking at the word ratio And the topic we are looking at which is images it basically means The size length and width and height of an image the are the Measurements that are looked at through each of the Images. In this picture you can see the Different shape and sizes of Each television you can easily See the difference becauseThis is an aspect ratio of each sizes Each of them are bigger and Wider thanof prints and monitors. each one .Basically what aspect ratio is(as i mentioned in the paragraph above)Measurements in and around the photograph.
  7. 7. File Formats The different types of file formats In digital printing are... JPEG, TIFF, GIF, PSD, PDF, EPS.The use of JPEG is to create an existing work into one image pageThe use of TIFF contains layers that can be attached to an image file for Rasta andVector images and produced into a high quality image.GIF supports images only up to 8 megapixels which allows images reference a paletteUp to 256 distinct colors.Basically what PSD is a software that would support images to a high megapixels andResolution.PDF is a file that you can save any image or work document and then can be reopenedInto a software for example illustrator Photoshop.EPS is a file that contains 2d vector graphics , bitmap images and text it also includesEmbedded images.
  8. 8. Color ModelsThe different types of color models are RGB color and CIE color.RGB color – the colors that are included in RGB mode is the colors you can see in the diagram CIE color are the colors you can see in the bottom diagram and the difference between this and RGB is RGB is much brighter than CIE
  9. 9. Adobe Photoshop• A popular high-end image editor for the Macintosh and Windows from Adobe. The original Mac versions were the first to bring affordable image editing down to the personal computer level in the late 1980s. Since then, Photoshop has become the de facto standard in image editing. Although it contains a large variety of image editing features, one of Photoshops most powerful capabilities is layers, which allows images to be rearranged under and over each other for placement. Photoshop is designed to read from and convert to a raft of graphics formats, but uses its own native format for layers
