<p>1、献上茶花一朵，这个茶花和背景有鲜明的对比，很容易用通道10秒中抠出来；<strong>复制背景图层</strong>，养成一个好习惯，把图层拖到新建框就可以了；</p>

<p>2、打开通道，选择<strong><font color="#ff0000">蓝色通道</font></strong>，按住<strong>ctrl健</strong>点击<strong>蓝色通道</strong>对选区进行选择；</p>

<p>3、用<strong>快速选择工具</strong>，对选取进行增删；【<strong>默认为+号</strong>，按住alt键为减少选区】</p>

<p>4、为了更清楚可以切换到RGB通道进行增删，结果如下，新建一个透明图层，<strong>在选区图层直接ctrl+x，到透明图层ctrl+v，</strong>增加一个黑色图层背景，最终效果就是这样的了；</p>
