Before the three signals for red, green and blue enter the matrix circuit, where the color and the hd component signal is processed consisting of the luma signal for luminance Y and two chroma signals R-Y and B-Y. So adjusting the BLACK GAMMA level black tonal reproduction, color saturation and color reproduction are affected.</p> <p>The <strong>Y BLACK GAMMA</strong> function allows to apply gamma processing only to the luminance signal. It mixes the resultant signal with the color differnce signals to create the final output. So we can adjust shadows, the black and dark areas in the images independently without affecting colors. However, since Y BLACK GAMMA mixes the deepend shades of the shadows with the final output, colors may darken or noise may become visible. Check your monitor when using BLACK GAMMA and Y BLACK GAMMA functions. Keep in mind that noise is hard to evaluate on the monitor on location. In postproduction level of noise allways seems to be much higher than you thought it would be on location.</p> <p align="center"><img src="y-blk-gamma-circuit.jpg" width="596" height="109"></p> <p>. </p> <p align="right"> </p> </td> <td align="right" valign="top"><img src="../_gfx/leiste_r.gif" width="2" height="100%"></td> <td valign="top"><table> <tr> <td width="10" height="0"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="10" height="1"></td> <td width="150"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="150" height="1"></td> </tr> <tr class="subnavigation"> <td rowspan="10" align="right" valign="top"> </td> <td valign="middle" class="navi_2gr"><a href="01.intro-digital-basics.htm"><font color="#FFFFFF">Intro</font></a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2gr"><a href="gamma.htm">Gamma</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="dynamic_range.htm">Dynamic Range</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="blk-gamma.htm"><font color="#CCCCCC">BLK-Gamma</font></a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="y_blk-gamma.htm">Y BLK-Gamma</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee.htm">Knee</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee-sat.htm">Knee Saturation</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee-aperture.htm">Knee Aperture</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="detail.htm">Detail</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="crispening.htm">Crispenng</a></td> </tr> <tr class="subnavigation"> <td align="right" valign="top"> </td> <td valign="top" class="navi_2we"><a href="level-depend.htm">Level Depend</a></td> </tr> </table></td> <td align="right" valign="top"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="15" height="1"></td> </tr> <tr> <td> </td> <td> </td> <td class="story"> </td> <td> </td> <td> </td> <td> </td> </tr> </table>   <table width="1080"border="0" cellspacing="0" cellpadding="0"> <tr> <td><img src="../_gfx/spacer.gif" width="1" height="1" /></td> <td><img src="../_gfx/spacer.gif" width="390" height="1" /></td> <td><img src="../_gfx/spacer.gif" width="250" height="1" /></td> <td><img src="../_gfx/spacer.gif" width="300" height="1" /></td> <td><img src="../_gfx/spacer.gif" width="10" height="1" /></td> </tr> <tr class="siteinfo"> <td height="25"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="10" height="1" /></td> <td valign="middle" align="left"> tomimages:::: <a href="../impressum.htm"><font color="#FFFFFF">Impressum</font></a> | <a href="../kontakt.htm"><font color="#FFFFFF">Kontakt</font></a> | ©2007 Thomas Bresinsky</td> <td> </td> <td valign="middle" align="right"><a href="http://www.neue-horizonte-film.de"><font color="#FFFFFF">Neue Horizonte Film:::: und Medienproduktion</font></a></td> <td><img src="../_gfx/spacer.gif" width="1" height="20" /></td> </tr> </table>  </div>  </div>  </body> </html>
