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

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

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

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

6. Cahaya Bangsa Classical School Multimedia and weBLOGging (C) 2010 Digital Media Production Facility 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 Pixelslandscape Resolution | 6 03 – Still Pictures – 02 – Basic Shapes

Cahaya Bangsa Classical School Multimedia and weBLOGging (C) 2010 Digital Media Production Facility Color Depth http://en.wikipedia.org/wiki/Color_depth 2 n, 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 2 24 = about 16.7 Million Colors CYMK is Cyan, Magenta, Yellow, Black. Builds 4 color channels 4 x 8 = 32 bits color data, builds 2 32 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) Resolution | 7 03 – Still Pictures – 02 – Basic Shapes
