  2. 03 – Still Pictures – 01 – Basics OBJECTIVE | 2 OUTLINE • Objective • Raster (Bitmap) vs Vector • Resolution • Color Depth Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School

  3. 03 – Still Pictures – 02 – Basic Shapes OBJECTIVE | 3 Possess the understanding of Basic Still Picture Component Enable to differentiate Vector or Raster graphic Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School

  4. 03 – Still Pictures – 02 – Basic Shapes Vector Graphic | 4 Vector Graphic • Use mathematical vector computation • Basic shapes • Basic color fill • Basic color gradient • Basic texture fill • Over exposure will not cause pixellation Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School

  5. 03 – Still Pictures – 02 – Basic Shapes Raster Graphic | 5 Raster (Bitmap) Graphic • Taken from outside source as photographic information • Store information pixel by pixel with color information • Over exposure will cause pixellation Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School

  6. 03 – Still Pictures – 02 – Basic Shapes Resolution | 6 Resolution • Digital to Analog Converter represents digital data in logical domain to the physical domain • Printer uses DPI (Dots per Inch), how many dots can be reproduced in 1 inch. The more DPI, the more high resolution the printer is • Display uses pixel, defined by width x height. The more pixel, the more resolution, and the more detail images are reproduced • Standard VGA camera : 640 x 480 = 307,200 pixels or 0.3 Mega Pixel. Aspect Ratio = 4:3 or 1.3:1 • Full HD : 1920 x 1080 = 2,073,600 pixels or 2 Mega Pixel. Aspect Ratio = 16:9 or 1.78 : 1 • Canon EOS 1Ds MK3 landscape sample picture produces 3744 x 5616 = 21,026,304 or 21 Mega Pixels Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School

  7. 03 – Still Pictures – 02 – Basic Shapes Resolution | 7 Color Depth http://en.wikipedia.org/wiki/Color_depth • 2n, where n is the number of bits, base on condition “on” and “off” • Default color channels : RGB and CYMK • Each channel contains 8 bits of data • RGB is Red, Green, and Blue. Builds 3 color channels • 3 x 8 = 24 bits color data, builds 224 = about 16.7 Million Colors • CYMK is Cyan, Magenta, Yellow, Black. Builds 4 color channels • 4 x 8 = 32 bits color data, builds 232 colors, considered mis-description of color depth • True 32 bits color data consists of 24 bits color + 8 bits non color data, such as Z (depth of field), alpha channels (for transparency), and bump mapping (surface perturbation rendering) Multimedia and weBLOGging(C) 2010 Digital Media Production Facility Cahaya Bangsa Classical School
