excel零基础入门？

个人认为，从零开始学习Excel可以参考以下十个步骤：

第一阶段：熟悉Excel界面

简单来说，就是把Excel上方工具栏中的那些按钮都点开看一下，熟悉一些都有哪些最基本的功能，以及如何使用这些功能。这些都是最基本的点击式操作，没有任何难度。

第二阶段：学习Functions

函数不需要所有的都学习，最基本的统计求和函数要会用，最基本的查找匹配函数要会用，接下来就是函数之间的嵌套应用，这些都掌握了之后，你再可以学习一下与自身业务相关的一些函数，这都没有什么难度，当你把这些函数都搞定了之后，再学习数组。掌握了数组，你就很了不起了。在这里推荐一本关于Excel函数方面的书，书中介绍了最基本的75个函数，只要掌握基本用法，后面的灵活运用就靠自己了，书名为：75个Excel函数搞定一切

第三阶段：基本的Graphs

Excel几乎可以绘制各种各样你所看到的图，而且十分方便，只要你掌握这些绘图的基本方法与原理，你同样可以绘制出非常漂亮的图表。当你掌握这些基本的图表制作技巧之后，你就可以进行自我创新，创造出让别人佩服的图表。市面上关于Excel图表的书籍很多，个人觉得最适合新手的是这本书：

ps零基础入门？

1,先了解位图和矢量图的区别。熟练掌握工具的基础和运用。

2,了解acr，adobe camera raw，这个处理图片很有用。

3,理解色彩关系，掌握各种调色技巧，色彩平衡，色相饱和度，可选颜色（相对，绝对），这些用的多，照片滤镜查找颜色那些用的少。

4.掌握图层的混合模式，各种混合模式有不同的效果，掌握渐变映射和通道混合器，不一样的设置有不一样的效果。

5,ps里面各种滤镜效果都是给图片加分的，有各种各样的效果，大家可以尝试运用各自滤镜有什么效果，用的比较多的有高斯模糊，usm锐化，高反差保留等等等等。

零基础摄影入门？

一、拍摄

 1、光圈优先大多用在拍人像以及风景时光圈优先就是手动定义光圈的大小,相机会根据这个光圈值确定快门速度。 由于光圈的大小直接影响着景深,因此在平常的拍摄中此模式使用最为广泛。 在拍摄人像时,我一般采用大光圈长焦距而达到虚化背景获取较浅景深的作用,这样可以突出主体。 同时较大的光圈,也能得到较快的快门值,从而提高手持拍摄的稳定。 在拍摄风景这一类的照片时,我往往采用较小的光圈,这样景深的范围比较广,可以使远处和近处的景物都清晰,同样这一点在拍摄夜景时也适用。 

2、快门优先多用于拍摄运动的物体上,例如体育运动、行使中的车辆、瀑布、飞行中的物体、烟花、水滴等等。 与光圈优先相反,快门优先是在手动定义快门的情况下通过相机测光而获取光圈值。 

快门优先多用于拍摄运动的物体上,特别是在体育运动拍摄中最常用。 很多朋友在拍摄运动物体时发现,往往拍摄出来的主体是模糊的,这多半就是因为快门的速度不够快。 在这种情况下你可以使用快门优先模式,大概确定一个快门值,然后进行拍摄。 并且物体的运行一般都是有规律的,那么快门的数值也可以大概估计,例如拍摄行人,快门速度只需要1/125秒就差不多了,而拍摄下落的水滴则需要1/1000秒。 

总之,在光圈优先的情况下,我们可以通过改变光圈的大小来轻松地控制景深,而在快门优先的情况下,利用不同的光圈对运动的物体能达到很好的拍摄效果。 这两者都要灵活运用,满足我们不同情况下的拍摄要求。 

二、人像拍摄 首先,要用到长焦,3――4倍的长焦非常适合拍人像,广角端会使得人像有些变形,不好看,超过4倍甚至更长焦会使得人脸过于扁平,不够生动。 其次,光圈优先,选择大光圈,大光圈可以使得快门变快,减少晃动,并且使得背景尽可能的虚化。 最好选择点测光,对人脸点测光,并使用曝光锁定。 因为其他测光方式容易受到衣服颜色的影响,使得人脸曝光不正常。 

最后,构图。 人像最好占到1/3-1/2,并且脸部在上方1/3处(从下看是处)。 这样拍出的人像片就会生动,有视觉的冲击力,让人看着好看。

数学入门零基础？

零基础应该如何学习数学

　　1.熟练掌握基本概念，基本规律和基本方法。基础不牢固，学再多知识，做再多题也没用。

2.做完题目一定要认真总结。思考这道题考的知识点是什么？以后再遇到相似的题目就会很轻松的解决。

3.举一反三。要尽可能掌握题型的多种解题方法，这样可以发散思维，培养自己的分析习惯。从而找出最优解，最佳答案。

　4.分析各章节的内容，使之互相联系。要将所学知识贯穿在一起，将前后知识融会贯通，连为一体。这样能帮助我们系统深刻的理解知识体系和内容。

　5.利用口诀将相近的概念和规律进行比较，搞清楚它们的相同点，区别和联系，从而加深理解和记忆。使知识条理化，系统化。

Excel0 foundation introduction?

The individual thinks, from 0 it is OK to begin to learn Excel referenced and the following 10 measure:

The first phase: Be familiar with Excel interface

Simple for, it is a tool of Excel upper part those medium pushbutton nod column to look, a few more familiar have what the basiccest function, and how to use these functions. These are the basiccest click type operation, without any difficulty.

The 2nd phase: Learn Functions

Function does not need all learn, function of the basiccest statistical sue for peace wants to be able to be used, the basiccest search match function to want to be able to be used, it is the nest application between function next, after these mastered, you can learn a few function related to oneself business again, this does not have what difficulty, get these function when you after was being decided, learn array again. Mastered array, you are very marvelous. Recommend a book about Excel function respect here, 75 the basiccest function introduced in the book, want to master main use only, from the back apply neatly rely on oneself, the title is: 75 Excel function is done decide everything

The 3rd phase: Basic Graphs

Excel is almost OK scale is various the picture that you see, and very convenient, want you to master the basic method of these plot and principle only, you are likewise OK scale gives very beautiful chart. After mastering these basic chart to make skill when you, you can undertake ego innovates, create the graph that others of sell one's own things admires. The about Excel chart book on market is very much, the individual feels what fit a new hand most is this book:

Ps0 foundation introduction?

1, understand the distinction of bitmap and vectorgraph first. The foundation of adroitness control tool and apply.

2, understand Acr, adobe Camera Raw, this processing picture is very useful.

3, understanding colour concerns, master all sorts of mix colors skill, colour balance, hue degree of saturation, optional color (opposite, absolutely) , what these using is much, photograph filter lens searchs color what those using is little.

4. grasps the mixture pattern of graph layer, all sorts of mixture mode have distinct effect, master gradual change map and passageway blender, different setting has different effect.

5, all sorts of filter lens effects add cent to the picture inside Ps, have various effects, everybody can try to apply respective filter lens to have what effect, used comparison has gauss faintness more, usm acute is changed, tall contrast reservation is waited a moment etc.

Introduction of 0 foundations photography?

One, film

 1, aperture is preferential use in mostly take figure and view days group preferential it is the measurement that the hand uses definition aperture, photograph opportunity is worth affirmatory shutter speed according to this aperture. Because the size of aperture is affecting depth of field directly, in because this is in,filming usually, this mode is used most extensive. Filming when figure, I use the effect that big aperture grows focal length and achieves empty to change setting to get more shallow depth of field commonly, can stress principal part so. At the same time bigger aperture, also can get faster shutter is worth, raise a hand to maintain filmed stability thereby. Filming scenery when this kind photograph, I often use lesser aperture, the range of such depth of field is wider, can make the scenery of far and vicinity clear, same this are filming when night scene applicable also.

2, shutter is preferential and multi-purpose on the object that moves at filming, for example the object in the car in athletic sports, exercise, chute, flight, firework, water is waited a moment. Preferential and as contrary as aperture, shutter is preferential be light is measured through camera below the condition that changes definition shutter in the hand and get aperture value.

Shutter is preferential and multi-purpose on the object that moves at filming, film in athletic sports especially in the most commonly used. A lot of friends are filming discover when mobile, often film the main body that come out is ambiguous, because the rate of shutter is not quite rapid,this most is. Below this kind of circumstance you can use shutter preferential mode, decide a shutter is worth probably, undertake filming next. And of the object moving have the law commonly, so the numerical value of shutter also can estimate probably, film for example pedestrian, shutter speed needs 1/125 second only about the same, and film the water of whereabouts needs 1/1000 second.

Anyhow, in aperture first case falls, we can dominate depth of field easily through changing the size of aperture, and in shutter first case falls, use different aperture to be achieved to content physical ability of motion film very well the effect. This both wants to be applied neatly, satisfy what we do not fall with the circumstance to film requirement.

2, figure films above all, should use long anxious, 3 -- the figure of long anxious very comfortable in time of 4 times, extensive role end can make figure some are out of shape, not good-looking, more than 4 times longer even anxious meeting makes person face too compressed, not quite vivid. Next, aperture is preferential, choose big aperture, big aperture can make shutter becomes fast, reduce rock, and make setting as far as possible empty is changed. Best selected element measures light, to person face the dot measures light, use exposure lock to decide. Get easily because of the other way that measure light the influence of dress color, make person face exposure abnormal.

Finally, composition of a picture. Figure had better occupy 1/3-1/2, and facial ministry is in place of upper part 1/3 (from next seeing is place) . The person photo that such patting go out is met vivid, have visual wallop, let a person look at good-looking.

Mathematical introduction 0 foundations?

How should 0 foundations study maths
