3. m ultimedia: building Blocks Building Blocks are things or modules required to create anything Multimedia building blocks are parts which are combined together to form a project. 3

4. Graphics Multimedia applications are mostly graphic. The content specialist is responsible for providing the production team with graphics photos logos colors 4

5. Vector Graphics However , vector images are more precise and require less memory. Vector’s are scalable with out losing resolution or quality 5

6. Basic Properties Determine whether the image will be printed or displayed on a monitor or projector Select the Area to scan Decide the scanning resolution of the resulting digitized file Decide the amount of light and contrast desired for the resulting image Determine the color cast you want to eliminate during the scan 6

7. Size, Resolution Factors to consider : Size in bytes Use of image How much manipulation or editing 7

8. Note The higher the image resolution the greater the file size Do not lower the resolution and later increase the resolution 8

9. Image editing Cropping Output‐Level Correction During scanning process the images losses resolution, contrast, and details in the shadows. The levels dialog box enables you to correct the output levels of RGB Brightness and Contrast Adjustments Filters 9

10. colors H uman can differentiate among millions of colors, or hues, consisting of combinations of RGB Brightness or lightness is the percentage of black or white mixed in a color Saturation is the intensity of the color where 100% is pure and 0 is white, black, or gray. 10

11. summary We have discussed building blocks to create a multimedia project Graphics Image Editing Colors Vectors Size and Resolution Sound, Audio 11
