Talking about how to learn PS: Methods for beginners to learn PS – PS basic tutorial

I personally am a graphic designer and also do video post-production and play with flash and realserver application programming

I can say without hesitation that all the things I have used in all my work in self-study of classic diving are learned from the classics. I think self-study and asking less questions is the best way to learn. If you search my posts on BI, you will know that I rarely ask questions. Of course, he is also very selfish and hardly answers any questions = =|||

I have read a lot of posts in the PS area, but there are posts that I will never click on to read the content just by looking at the title. For example, “broken paper effect”, “crystal word effect”, “XXX effect”…

Such posts are almost completely nutritious. I haven’t seen anything like this since I was a rookie.

I even personally think that watching such things is harmful to newbies. Many PS students around me hold the book “1000 Examples of PSXXX Effects” and something like that every day and look at it. Whenever they come across something they need to do at work, they run to check if there are any ready-made effects. If it doesn’t work, they Came to ask me if I had any ready-made materials. I would never answer no to such people. And these people, especially when it comes to dealing with things like portraits that need to make the image look as real as possible.

Why is this? Because when they learn PS, they only know how to do it but not why.

For example, if we want to create a sphere with a crystal effect, many people just click on the crystal style style that comes with PS, and then adjust it themselves, and it’s OK. But if I take a complicated object, such as a snake-shaped object that twists and turns, and ask him to turn it into crystal for me, he will be depressed. If I get something like this, I will definitely make a selection of highlights and darks with color levels first, and then it will just be a matter of coloring and correcting the light. To put it plainly, style is just a simplification of optical issues, and the relief effect will never be as beautiful as hand-painted selections. Of course, I’m not asking you to complicate the problem. I’m not asking you to use a hand-painted tablet to make every button. What I want to say is that we need to know why we do what we do in order to cope with complex situations.
Since my job is in the fashion industry, a large part of it has to do with dealing with human figures. For me, this is no more than simply drawing buttons. If I cannot correctly understand the concept of channels and correctly use optical formulas to process images in PS, it will definitely be a disaster for my work.

Now let’s talk about some of the problems in portrait and nature photo processing that I am best at.

When you get a photo, first of all, you must not think about what the finished document will look like, what kind of lace it will have, whether you want to add some blue sky and white clouds on the head of the person. The first thing we need to do should be to restore the truth. That is to say, remove the unreal things in this photo. These things are unnecessary elements in the design.

PS is a mathematical thing. For example, you only need the value of the X parameter, but now that the real photo has not been restored, the Y parameter is attached. If you don’t do the step of restoring reality, then all subsequent operations will carry Y parameters. Y parameters, this design junk element, will cause more and more damage to the image as your image processing steps increase.

Especially after you perform some mathematically irreversible operations you will never be able to escape the impact of Y on the final result.

Example: There is an image with a color cast. If you don’t correct the color first and directly perform an irreversible operation like blurring, then no matter how you adjust the color in the future, the final result will be different from the correct result obtained by adjusting the color first and then blurring it.

I mentioned in a post before that there are several reasons for poor image quality

1. Abnormal light source, such as abnormal color cast, contrast, overexposure, etc.
2. Digital camera noise includes the material texture of the scanned image, etc.
3. Defects in the photographed entity itself, such as freckles on the face, apples, etc. There is a bug-eye picture sound that you don’t want, which has been watermarked etc.

We should resolve these issues first before further processing the image and adding the design elements we want.

I have always had a desire to pursue truth. If time permits, I would like to completely use mathematical and optical methods to process my images.

And I will not do anything that damages the natural data of the image unless absolutely necessary. For example: the color of a picture is very difficult to adjust, but the number of colors in the image is very small. At this time, others would just remove the color and re-paint it. I will definitely start with color levels and channels and try to restore the image. I will give up unless I confirm from the channel information that harmful and mathematically irreversible operations have been performed on this image.

Maybe some people say that what I said is so complicated just because I want to show it, so let me give you the simplest example. There is a hole in the middle of an apple. Now we’re going to remove the hole. Obviously everyone will use a repair tool or a stamp to copy nearby pixels to repair them. Wouldn’t you be so stupid as to take a brush to pick up the color and then draw a stroke to fill the hole? !

In fact, you all know that it is right to keep things as real as possible. It’s just that many rookies are not as experienced and good at summarizing as I am.

As mentioned aboveTo restore the correctness and importance of true thoughts, let me talk about some things I learned about PS.

When I first came into contact with PS, I was using FW at an intermediate level, and I didn’t even know there was such a thing as PS. The reason why I later chose PS and completely gave up on FW was because one day I saw a person fill in 0.5 when feathering the selection in PS! I originally studied software engineering, and I have always wanted to pursue accuracy when it comes to numbers. At that time, I was depressed. Why can PS be so accurate, but FW can only make a 1-pixel selection? Moreover, FW’s W tool is absolutely rubbish compared to PS’s W tool. So I turned to learning PS on the spot.

I was still a student at that time, and it was not easy to access the Internet. I had no idea that the world was so big and there were textbooks all over the place. I finally got an E version of the PS6. There were no instructions or teaching materials, so I had to click on the tools one by one to see what they could do. Then I guess what this PS tool does based on my familiarity with FW. Since it is a guess, it is bound to be wrong. In order to avoid errors, the easiest way is to understand programmatically what operations it does. In other words, it was at that time that my interest in understanding PS filters from mathematical formulas was promoted.

It wasn’t until many years later that I finally had the opportunity to visit the darkroom of a photographer friend and look at the photos posted under the red light. At that moment, I suddenly understood what a passage was. I also learned that it is most intuitive to learn PS and understand it from the optical formula.

These ideas have always influenced my future study of the particle system concept of 3D Marx, the lens effect concept of AE, the concept of FLASH formulaic motion, etc. It can be said that pursuing the reality of mathematics and physics benefited me greatly from my later study and understanding of various software.

When I talk about these things, I want to show the way for newbies. The important thing in learning PS is to learn what operations each tool does mathematically, and how you can intuitively understand it from an optical and physical perspective and use it. .

Although I am not an expert, I can say that I have gotten started with PS. For those newbies who haven’t started yet, revise your learning methods. We must use professional methods to solve our work problems. Pursuing authenticity is the professional approach
