PS怎样合成炫酷的水人头像照片
合成炫酷的水人头像照片制作过程也不是很复杂,制作之前需要先准备一些水珠素材或笔刷。然后用滤镜制作一些类似液体的背景,再加入人像并修改混合模式做出蓝色效果,后期添加水珠装饰即可。最终效果 一、新建一个A4大小的文档,背景填充深蓝色:#033670。 二、前景色设置为深蓝色,背景色为黑色,执行:滤镜 > 渲染 > 云彩,确定后再执行:滤镜 > 滤镜库 > 素描 > 铬黄渐变,这一步是为了做液态的背景。 三、新建一个图层,填充刚刚的深蓝色,变图层模式为“叠加”,留着待用。

风景中的数学题告诉你这样构图也可以
请大家认真回想,国高中教的数学课,还记得多少?光是听到sin、cos、tan或是函数,即使干了三杯咖啡也昏昏欲睡吧!但是你可想象得到,大多数人们所痛恨的数学题,竟然能套用在「摄影」上,是哪个数学奇才这么厉害,能放眼放去都是函数? Nikki Graziano出生于美国纽约罗彻斯特,父亲曾在大学教摄影,母亲则是教电器工程的,虽然曾在高中时,摸过父亲的4x5相机而对摄影产生兴趣,甚至想大学就念摄影,当想到出社会得跟人挤破头才能进报社工作,就放弃改念数学,副修艺术史。Found Function系列作品,以数学函数与摄影结合在一起。可别以为它相当简单,每张照片的数学题,可都是千真万确的,它可是花了Nikki三至四年的时间,在每周散步时,用哈苏503CW与彩色负片记录这些景致,再利用滚筒扫描成数字文件,编排搭配出合适的数学函数。

详细解说PS图层混合,通道,计算,选择和载入高光区
本文主要由苏色老师用实例来讲解Photoshop图层混合,通道,计算,选择和载入高光区等命令的使用和原理.先向柔软老师表达一下敬意,柔软的很多实例,其实对我们学习PS是非常好的启迪,不管是柔软老师,还是元素老师,还是贫农地雷和老编,还是邮差和关文涛和李涛,以及更多在影像行业的从业者,他们掌握的是PS的核心――是图层混合,是通道,是选择,是色彩......苏色用下面这张图片,和大家聊聊怎么去综合把握和应用这些知识。苏色尽量用平实话的语言和细致的讲解,细致看完苏色帖子的,如果没有对PS有个重新的认识,呵呵,尽管拍砖,不过,苏色不会陷入这个色怎么调那个效果怎么做这样的论战,所以,希望大家理解,细致看完苏色思路,再得出自己的分析。苏色参加外拍的原图――惭愧,有点闷,色彩也很灰,要修要调。第一步:向柔软老师致敬,我们用“柔软淡色调”的方法试试看会是什么效果?1、RGB转LAB模式,选择明度通道,CTRL+A,CTRL+C,转回RGB,CTRL+V;2、LAB模式下的明度通道就作为RGB模式下的一个图层参与了图层混合;3、“柔软淡色调”告诉我们,明度通道作为RGB下一个图层参与对原图层的混合后,混合模式选择正常,不透明度选择80%,好,我们看看是什么效果?4、显然,不是苏色想要的效果,并不是说柔软淡色调不好,是不适合这张色调和环境的图片,但是,柔软老师的方法启迪了我们的思路。

两种风格的烛光人像摄影
点燃蜡烛,风情别样。然而那跳动的火光会让我们遇到许多难题,拿起相机,跟随摄影师一起创造烛光之下的浪漫大片吧。 以烛光作为主光源进行拍摄,会出现很多的问题。比如光源微弱分散、光线不稳定,其实只需要简单的方法就可以解决。 足够的蜡烛保证气氛 烛光摄影最大的挑战就是环境光线不足。使用更多的蜡烛可以增强光线,提高快门速度。当然,我们要注意主光源蜡烛的亮度最大,保证我们可以借助主光源的蜡烛拍摄人脸。而其他环境蜡烛,只要把当时的温暖气氛表现出来就可以了。当我们只用一个蜡烛或者是把好几个蜡烛放一起,会在脸上造成明显的阴影。要注意把蜡烛分散错落地布满小空间更能制造浪漫的气氛。 1 有一定高度的烛台,作为主光源 2 带螺纹的蜡烛更有造型感及古典气息 3 矮蜡烛可以在多处摆放,增加现场亮度 你还可以拍摄面部特写 我们为了强化模特面部轮廓和线条,可以拍摄模特面部的特写,让模特自然地趴在桌子上,拍摄模特自然、慵懒的状态。要注意模特此时的头发不要遮挡住脸部,将刘海拨向一边。模特的眼睛可以不用注意镜头,而是向下或者偏向一边,营造一种若有所思的朦胧浪漫之感。这样,在温暖的烛光下,模特面部的轮廓格外动人,而均匀的光线不会让模特的脸上有明显的阴影。可以利用大光圈,将前景的蜡烛虚化,只留下光晕。 拍摄模特的面部特写,可以将模特的面部线条表现得淋漓尽致,而模特若有所思的眼神会加深浪漫的意境

this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753516148.jpg');}" src="/Files/photo/2007-4/2/07421544495218.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 11. 可以使用编组(按Ctrl+g)。screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753517521.jpg');}" src="/Files/photo/2007-4/2/074215444920897.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 12. 加入一些细节会更加真实。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7;

this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 13. 最后拼合图层之后,整体的调色阶,用加深和减淡作调整。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753517337.jpg');}" src="/Files/photo/2007-4/2/074215444946254.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true;

数码图像快捷曲线调色法
在Photoshop中打开图像之后,我们可以使用快捷键 CTRL+ M 调出曲线调整功能。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753557734.gif');}" src="/Files/photo/2007-4/2/074215444958473.gif" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 在使用曲线调整功能之前,我们先简单介绍一下曲线工具的原理。Photoshop把图像大致三个部分 :暗调、中间调、高光。比如下面这幅图像: screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753558621.jpg');}" src="/Files/photo/2007-4/2/074215444964977.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 我们可以使用“去色”命令将彩色图像转化为灰度图像,这样就可看到明暗的分布:天空部分属于高光,树木和草地属于暗调。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753558371.gif');}" src="/Files/photo/2007-4/2/074215444941617.gif" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 在曲线面板中那条直线的两个端点分别表示图像的高光区域和暗调区域,直线的其余部分统称为中间调,两个端点可以分别调整。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/2006875360112.gif');}" src="/Files/photo/2007-4/2/074215444979533.gif" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 下面两幅动画演示了单独改变暗调点和高光点的效果,其结果是暗调或高光部分加亮或减暗。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7;

this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0> 而改变中间调可以使图像整体加亮或减暗(在线条中单击即可产生拖动点),但是明暗对比没有改变(不同于电视机的亮度增加),同时色彩的饱和度也增加,可以用来模拟自然环境光强弱的效果。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/2006875366876.gif');}" src="/Files/photo/2007-4/2/074215444940555.gif" onload="if(this.width>screen.width*0.7) {this.resized=true;

要加亮粉红,则减暗绿色; 要加亮金黄(金黄由红和黄组成),则需要同时加亮红色和减暗蓝色。 现在我们试试将天空部分的色彩改为金黄。由于天空属于高光区域,所以我们要加亮红通道的高光部分。 screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('UploadFiles/200602/20068753611148.gif');}" src="/Files/photo/2007-4/2/074215444956277.gif" onload="if(this.width>screen.width*0.7) {this.resized=true;

photoshop打造冷色效果
在形色上看到这个贴子,很红的,我了也很喜欢,它那个太详了,不好转,所以自己做了一下。 图片附件: 1.jpg (2006-7-8 01:20, 20.43 K)图片附件: 2.jpg (2006-7-8 01:20, 18.93 K)图片附件: 3.jpg (2006-7-8 01:23, 49.84 K)图片附件: 4.jpg (2006-7-8 01:23, 67.21 K)图片附件: 5.jpg (2006-7-8 01:23, 76.61 K)图片附件: 6.jpg (2006-7-8 01:23, 58.5 K)图片附件: 7.jpg (2006-7-8 01:24, 81.65 K)图片附件: 8.jpg (2006-7-8 01:24, 60.44 K)

PS合成蜗牛背上的梦幻房子
1、在Photoshop创建如下图所示的画布,设置长宽为1500*1100像素2、打开前景素材,选择多边形套索工具,如下图将前景物选择创建选区,然后用移动工具将前景移放到画布的下半部。按Ctrl+T调出自由变换工具,调整角度形成水平放置的效果。 1、将常春藤素材打开,然后选用多边形套索工具将其中一部分抠出,贴到蜗牛壳上。

PS合成璀璨雨夜中独行的女孩
1、在Photoshop中创建新画布,尺寸设置为2000像素*1333像素,具体设置如下。 2、将人物素材打开,然后利用移动工具将人物移放到画布中。 选择人物图层,选用套索工具,将人物脸部选择起来。然后选择“滤镜>液化”,选择向前变形工具。从素材可以看到人物的眉毛太细,显得与眼睛距离很远,利用向前变形工具降低眉毛的位置,将嘴唇的位置要上移一点,将下巴拉长一点。 1、人像修饰完以后,就到背景颜色、亮度、对比度这些参数的调整了。选择“图层>新建调整图层>色相/对比度”,选择青色和蓝色,具体设置如下。调整蓝色和青色的表现效果是为了让画面更多彩,我们将会在最后一步看到效果。 2、选择“图层>新建调整图层>曲线”,添加曲线调整图层。在图层蒙版中用黑色画笔将除右臂外的区域遮蔽,如下图调整曲线,将右臂手肘部分调亮。 3、创建另外一个曲线调整图层,将除左下角部分外的区域遮蔽,然后如下图调整曲线,将左下角调暗,令场景像是逐渐消失在黑夜中。

PS照片合成教程
第一步:在photoshop 中打开这两幅图片。 第二步: 按住套索工具不放在吴奇隆图片的头部画一个圈,将头部圈住.(如下图) 第三步: 按住B键(在英文输入法下,以下也一样)将吴奇隆的头部拖到孙悟空图片上面。

PS移花接木
素材 合成效果 3. 这里是最要命的一步--合成边界。我们的希望是:较多地保留理想脸部的中间部分,例如鼻子、眼睛和嘴唇的线条,而使理想的面颊部分和米勒逐渐融合在一起。只要干过这事儿的都知道,这可不容易。多了不行少了不行,深了不行浅了不行。标准在哪儿呢?标准在通道里。点开通道面板,对理想面部找一个顺眼点儿的通道,比如说蓝通道,复制之。 4. 把这个复制的通道作为当前通道,先把无关的较强的地方抹黑,然后拉出色阶对话框,把黑三角向右移动一些(如果没有在先的抹黑准备,这个色阶是做不好的),得到 5. 这个通道看上去已经不错了,说它不错,是因为它较好地保留了面颊较弱的效应,同时较好地保持了更弱的趋势。
