收到。
不太理解的是--为什么要反转MASK.
我复制了一个LAYER以后(LAYER 1 COPY),点CURVE,点出CURVE ADJUSTMENT LAYER.然
后在CURVE ADJUSTMENT LAYER里面,可以调节相片亮度--把中心点往上拉。 -- 我
的理解是:这个相当于增强的SCREEN MODE。
按照你的方法,这个时候应该反转MASK.可是我按了INVERT钮(在MASK菜单下面),图
片直接就变成原始的了(ORIGINAL).不是那种象底片一样的图。
可是我如果这个时候点LAYER 1 COPY,我是可以用直接笔刷的。这样的话,相当与前面
做的都没有用。=== 我肯定是什么地方还是没有做对。
要是搞清楚原理,会更容易理解一些。
用CURVE ADJUSTMENT LAYER是让用笔刷的时候更好的选择需要处理的地方?
用MASK是为了将笔刷处理过的地方作用到原始的图片上去?--要是直接在LAYER 1
COPY上用笔刷,将来两个图(这个图和原始图)整合不到一块去?
不好意思,太笨了。

从前文我们知道,“我”是大脑中神经细胞连接模式的总和。这里还要明确一下,这个
连接模式不但是物质上的,同时也是信息上的。因为这种连接模式本身就是信息。大脑
中的信息存储并不需要另外一个单独的地方去存储,信息在神经网络中传输的过程中,
就已经存储在这个网络的连接方式上了。打个比方,比如有五个神经细胞组成的细胞群
,这五个神经细胞原来是以五边形的连接方式存在的,当有一个特定的外界电信号刺激
传过这个细胞群后,五个细胞的连接方式变成了五角星形。这种从五边形到五角星形转
变的过程就是信息的存储,即记忆。如果以后再有同样的一个外界信号传到这个细胞群
后,那个五角星的突触连接状态就得到加强,由短期记忆转化为长期记忆。这就是神经
网络(大脑)的学习过程。在这个学习过程当中,改变的是连接的方式,而不是在神经

从前文我们知道,“我”是大脑中神经细胞连接模式的总和。这里还要明确一下,这个
连接模式不但是物质上的,同时也是信息上的。因为这种连接模式本身就是信息。大脑
中的信息存储并不需要另外一个单独的地方去存储,信息在神经网络中传输的过程中,
就已经存储在这个网络的连接方式上了。打个比方,比如有五个神经细胞组成的细胞群
,这五个神经细胞原来是以五边形的连接方式存在的,当有一个特定的外界电信号刺激
传过这个细胞群后,五个细胞的连接方式变成了五角星形。这种从五边形到五角星形转
变的过程就是信息的存储,即记忆。如果以后再有同样的一个外界信号传到这个细胞群
后,那个五角星的突触连接状态就得到加强,由短期记忆转化为长期记忆。这就是神经
网络(大脑)的学习过程。在这个学习过程当中,改变的是连接的方式,而不是在神经

这个问题都没有人回答, 怪不得缺'艺术家'.
first, when u choose background layer, preserve transpr.. is grey, no way
to change it ok.
second, u must be using photoshop 5.o or above, right? in the layer panel,
there is a 'T' icon right? that indicates this layer is a type layer,
not a normal layer. before u can do any editing, u'll hv to convert it
back to normal layer. in the menu, layer-->type-->render.
wish it's not chinese photoshop, sth. different for it.
that's it.

well, IPv6 doesn't have the head checksum any more. It's true the upper
layer protocol shouldn't rely on the lower layer, but with modern transport
media, upper layer can "assume" lower layer has no or very little error

be
of layered TCP/IP is that upper layer does not depend on any specific
lower layer delivery.
