【转帖】老邮差的色阶调整图像教程
■老邮差 <BR><BR>清清楚楚黑白场 <BR><BR>拿到一张图片，首先从影调和色调上考虑，其中影调又包括反差、明暗、层次；色调主要是较正颜色。 <BR>这是一张普通的风光照片，就影调来说，这个片子反差较弱，调子发闷。 <BR>整个图像中既没有最黑的点，也没有最白的点。所以片子灰的厉害。<BR>data/attachment/forum/2004-3/200431783544647.jpg<br><BR>data/attachment/forum/2004-3/200431783630920.jpg<br><BR>data/attachment/forum/2004-3/200431783655256.jpg<br><BR>data/attachment/forum/2004-3/20043178371814.jpg<br><BR>data/attachment/forum/2004-3/20043178388514.jpg<br><BR>data/attachment/forum/2004-3/200431783845791.jpg<br><BR>data/attachment/forum/2004-3/20043178401275.jpg<br><BR> 轻轻松松点吸管 <BR><BR>这张片子在拍摄的时候，受现场环境影响，加之技术太凹，造成欠曝。片子反差很弱，影调不好。用Levels色阶进行调整很方便。data/attachment/forum/2004-3/200431784156456.jpg<br><BR>data/attachment/forum/2004-3/200431784224861.jpg<br><BR>data/attachment/forum/2004-3/200431784244455.jpg<br><BR>data/attachment/forum/2004-3/200431784315800.jpg<br><BR>data/attachment/forum/2004-3/200431784344127.jpg<br><BR>data/attachment/forum/2004-3/200431784412650.jpg<br><BR> 认认真真做手动data/attachment/forum/2004-3/200431784539414.jpg<br><BR>data/attachment/forum/2004-3/20043178462678.jpg<br><BR>data/attachment/forum/2004-3/200431784654621.jpg<br><BR>data/attachment/forum/2004-3/200431784711732.jpg<br><BR>data/attachment/forum/2004-3/20043178483659.jpg<br><BR>data/attachment/forum/2004-3/200431784829974.jpg<br><BR>
