这里介绍下在ps中打开PCD格式图片的详细步骤,需要的朋友可以参考下

步骤如下:

1、在PS中的选择打开PCD文件;
2、选择将要打开的文件大小;
3、设置Source(来源):设置为Kodak Photo CD 4050-6V3.4
4、设置destirnation(目标):设置为sRGB IEC61996-2.1

那种*真的人体文身效果如何做?

1、首先准备一花的图像和一副人的图像。

2、用钢笔工具,或是套索工具将头像多余的部分去掉。

3、将头像复制到花的图像上,生成新建图层Layer1,在图层面板上选择图层Layer1,然后单击下方的添加图层蒙版工具为Layer1添加一个图层蒙版。

4、置前景色为黑色,背景色为白色,在图层蒙版的状态下用黑色涂抹头像外不需要的部分,以显示出背景层的图像。 

5、双击笔刷工具,在笔刷面板中设置合成模式为“Color”。

6、用滴管工具单击花瓣,得到花的颜色,然后用笔刷工具在女孩脸部进行涂抹,这时人和花就溶为一体了。

7、按下ALT键的同时单击花瓣,得到花的颜色,然后用笔刷工具在女孩脸部进行涂抹,由于笔刷工具的合成模式设置为“Color”顶,因此,涂抹后只会改变女孩检部的颜色,而不会改变其饱和度和亮度,最后完成制作。

如何用PS中画一个立体状的球面?

先选择一个浮动的圆,再编辑一个三色渐变色,第一色为高光色,第二色为背光色,第三色为反光色(即比背光色稍浅一点的颜色),然后用球形渐变工具从浮动圆中的高光部分向背光部分拉出渐变。取消浮动即可。

如何添加外置滤镜?

添加外置滤镜,一般有两种可能。一种是,滤镜本身是安装版本,这样,你可以直接执行安装程序即可。

另一种就是滤镜并不是一个安装程序,就需要你己动手安装。Photoshop的滤镜目录一般在 Photoshop所在目录 \ Plug-Ins 下,直接将滤镜拷过去既可。

怎样去除毛边?

可以试着用路径工具或魔术棒勾出图象的外轮廓,再用Select下的Feather,然后反选再Delete,可能会好一点。

PS中如何输入特殊标识符号呢?

在字体状态下切换到"智能ABC"方式,右键单击输入法状态栏上的软键盘,你会看到各种符号及外文输入的菜单。还有一种方法,也是切换到智能ABC方式,左键单击软键盘,然后敲"V",再敲数字1-9,所看到的东西是一样的!可用PAGE DOWN及PAGE UP翻页。

怎样才能存储扣出来的图而不要后面的底色?

答:将虚线所选区域"copy",然后"paste",接着删掉底层, 最后"ctrl+s"。注意存储格式应为。PSD格式或者。EPS格式或。AI格式。

同一图像中用层效果做投影方向不相同的字这个效果该如何做?

答:做完了一个层后将其合并到背景,或合并到另一个空白层中,然后再做另一不同的投影

如何去除图片的网纹?

(1)扫一张画报或杂志的图片。

一般情况下,网纹的产生是由于画报或杂志印刷用纸的纹理较粗糙而造成的。在扫描时dpi 的值应该设置得高一些,分辨率越高,扫出的图片也就越大,相对的精细程度也就越高。较高的分辨率会为下一步的图片缩小和滤镜处理创造良好的条件。

(2)把图片调整到合适的大小。

在 Image 菜单下选择Image size 选项,弹出Image size对话框,确定其下的Constrain Proportions限制比例选项为勾选状态,在Pixel Dimensions 像素尺寸中将Width后的Pixels 像素,改为Percent百分比。此时的Width值变为100,这时你可以输入所需的百分比数值,将图片等比缩小。缩小后的网纹情况已稍稍减弱。

(3)用高斯虚化消除网纹。

在Window 菜单中选择Showchannels,这时出现了通道面板,四个通道分别为RGB、Red、Green和Blue。选择Red通道,图片显示为黑白效果。在Filter菜单中选择Blur→GaussianBlur,即弹出高斯虚化对话框。调整Radius值,控制虚化的范围,使Red通道中的网纹几乎看不到,图片内容微呈模糊状即止。接着照此方法分别调整Green和Blue通道,以使该通道中的网纹消失。最后回到RGB通道,这时的图片已经没有网纹的干扰了。(注意:Radius的值不可设置得过大,以免造成对RGB通道过大的影响使图片变朦胧。

(4)调整最后效果。

如果网纹过于清晰以导致Radius值设置较大,那么RGB通道中图片会有些模糊。如果想使图片的内容清晰一些,还可以执行Filter菜单中的 shapen->shapen清晰效果。最后,再用Image菜单中的Adjust->Levels或Curves选项设置你所需的对比度等数值,以达到最终满意的效果。

如何使一个矩形四周有明显的凹凸感?

画个矩形选择框填充,Filter>Blur>Gaussian Blur,设置圆角程度,然后Image>Adjust>Levels,把三个三角形都移到中间重合。

如何设置硬件,给PS加速?

检查硬件配置

1.充分利用内存

任何一种图像处理软件对内存的要求都很高,Photoshop也一样。如果你在使用Photoshop时,没有使用其它的一些大软件,这时你就可以将 Photoshop占用内存资源的比例提高。方法是:进行Photoshop,选择菜单下File\Preference\Memory &Image Cache命令,将Used by Photoshop的比例提高到80%~90%即可。

指定虚拟内存

在处理Photoshop时,内存被用完是很正常的,到时会大大影响Photoshop处理图像的时间,哪将怎么解决呢?方法是:你可以用硬盘来作为内存来使用,也就是常说的虚拟内存。请选择菜单下“File\Preference\Plug-Ins & ScratchDisks”命令。在这里的ScratchDisks下,你可以在硬盘上指定四个驱动器来作为虚拟内存,软件默认的虚拟内存是在 Windows\temp之下。当第一个虚拟内存被使用光之后,Photoshop会自动去使用第二个Scratch Dsik,这样就提高了执行速度。

释放内存与硬盘空间

在进行图像处理时,你所进行的所有*作将会记录在 Photoshop的History(历史记录)工作板中。这些*作包括:复制到Clipboard(粘贴板)、Undo(恢复)、Pattern(填充物)、Histories(记录)等几种,选择菜单下“Edit\Purge”命令。

进行这些*作之后,Photoshop会将这些图像和数据保存在内存里,使用该命令后,即将这些被占用的内存空间释放出来(RAM:"Oh!Freeden")这样就让Photoshop有更多的 Resource(资源)可用,自然就提高了效率。但注意,如果这些*作占用的内存比较少时,就没有必要使用啦!

除此之外,在处理大型图片时,Photoshop会自动产生一些临时文件,一般都很大,如果你处理的是一个20MB大小的宣传画时,那么临时文件可能就是 100~150MB。请在Windows\temp或在你设定虚拟内存的驱动器里,将产生的Photoshop临时文件*.yesp删除掉。
