CS123 | INTRODUCTION TO COMPUTER GRAPHICS<br />
Gamma<br />
<br />
Example: PC moni<strong>to</strong>rs have a gamma of roughly 2.5, while Mac moni<strong>to</strong>rs have a gamma of 2.2, so Mac<br />
images appear dark on PC’s<br />
Mac user<br />
generates<br />
image<br />
PC user<br />
changes image<br />
<strong>to</strong> make it bright<br />
PC user gives<br />
image back; it’s<br />
now <strong>to</strong>o bright<br />
<br />
Problems in graphics:<br />
Need <strong>to</strong> maintain color consistency across different platforms and hardware devices (moni<strong>to</strong>r, printer, etc.)<br />
Even the same type/brand of moni<strong>to</strong>rs change gamma values over time<br />
