Photoshop wonderful case of solution: three-dimensional light and shadow magic (1)


We are very enthusiastic to learn, are eager to see the variety of results-based approach, to see whether their work was recognized, this is a good thing, enthusiastic, willing to work harder, PS did not learn good reason.

But here I have to pour a cold water as some people have passion, but will be lost fatal, and you will learn PS in the process, confused, there is a "do not know how to do so" feeling.

What is the performance of this phenomenon? Is simply too much on meaningless without any extension, the effect of rigid pursuit.

Many people come to ask: What is this effect? How?

That the appropriate answer to what is it? - To do so. But do after that? Consider the following three questions.

- This effect can be any other change?

Effect of ever-changing, both design and service, whether it is pleasing or people access to information, the design is purposeful, so the design can not lead to results do. I want this effect, because it can achieve such a purpose. I, for example, crystal button, this effect is used to do? In order to be machine interface, there is a fresh, clean feeling, that button is a crystal-like, I studied the effect precisely because of this. Learn the effect that, if not used in human-computer interface, where you use it? This should be in-depth thought.

If you want to grow faster after learning of an effect should be more thinking, change some parameters and steps can be other effects? The practical effect of what? Not learned, the one, it seems to understand, and rote.

Let me give back to the button example.

One day you learned to use layer styles to create crystal button. But the next day the boss told you that he felt too delicate crystal button, metal button, he would like to change. How do you do? Ready to immediately go to the book, people immediately ask, metal buttons, how to do, or simply reply to your boss: I'm sorry, I just learned crystal buttons, metal buttons do not understand.

This work? Obviously very lazy behavior.

You should immediately think of the material is crystal crystal button, crystal or glass, there is as smooth surface, particularly arising from specular reflection, the same, the metal must also have, just because some rough surface reflecting weaker result.
Crystal button in your learning process, as it inevitably learn, that allows you to set the button produces three-dimensional effect, then, the same metal buttons must also require three-dimensional effect, these steps can be copied, or just need to adjust some small parameters.
These parameters do not know how? More than their hands to practice.

- Why the results?

This is an issue that many people have not seriously thought about. Crystal button, or give examples. Before Mac did not develop this crystal button, we did not expect such a crystal clear style will be popular in the world. Finally, when you see it, surprised it's fine, so would like to learn and for their own works. Wait a minute ~ You learn before ever wondered why people would think of it this style? Introduced through other examples, or observations in real life come from?

- Why use this effect?

Similarly, many people believe that this issue did not seriously considered. For example, you see someone painting a picture, in order to show the sun, glare effect that he has up, so people think that once lit up the entire screen; another example, someone designed a poster, showing a football match shooting star explosive power, he added some fire effects, the star seems to be the same as coming out of the fire. Why did he think of using this effect to increase the dynamic? If you use other effects, such as zoom lens speed gradient to generate a sense of right? Not the red fire, the magic of light blue, how?

Would like to clear these three issues, study the use of PS or PS will not get lost. Some users may be made to the book's examples done, the steps by heart, but to make their own independent if a work is always powerless. Do not know where to start with? Do not know how to arrange to have learned of the results? It is all piled up, or just pick one, or pick what kind? Why would such a situation, that is because you can not judge the whole, can not "create their own effects," not to speculate what other techniques used to achieve an effect. This continues, can only be a craftsman, but not handy to do a real design.

This is what I write here "topics for" reasons. Ago I wrote a "Photoshop topics for" also said that some of these feelings. At that time two years ago, two years later, has different ideas and experiences. So, I decided to write one, and then proceed from the purpose, talk about some common techniques, like how the changes in a series of effects.

This "topics for tutorial" will include the following majority. As the relationship between time and space, and can only send and writing side, the following directory structure is not the most complete. At the same time, I will be in each section, leaving some small operations. If you are interested, try.

Part I: three-dimensional
Part II: Light and Shadow
Part III: Texture
Part IV: Motion and Color

Each section of each of several types of practices are generally effective, as is the legislature made written legislation, it would be more likely to chaos in some areas, also please bear with. However, this article is to emphasize thinking skills, each department will result from the need to proceed against the step.

I have limited capacity, this tutorial belongs to initiate communication can cause you is enough, thank you.

Before the end of this introduction, please keep in mind a word (which may be the same old tune up): Photoshop, always just a tool.
