Does Photoshop have a built in filter that can be used as a circle?

You can do it without plugins.

The tutorial is pretty simple.

In fact, the proof questions in mathematics are not very difficult, the key is confidence and method.

1) It is necessary to master the most basic proof methods and common methods. For example, the proof and writing of triangle congruence, the proof and application of the Pythagorean theorem, the method of using equations and functions in geometric problems, etc.

2) is good at doing auxiliary lines, to master the practice of common auxiliary lines, such as high, vertical lines, etc., of course, the auxiliary line is not the more the better, generally not more than two (must do two auxiliary lines of geometry questions are more difficult questions) in the high school entrance examination geometry problems of the auxiliary line is generally not more than two, in addition to the need to master when to do what kind of auxiliary line, the general situation is for example, for example, to find the area we will make high, in the circle we often even the radius and so on.

3) Of course, you can use algebra (arithmetic and equation functions) to solve some geometric proof problems for some problems.

4) Be good at finding the relationship between known conditions and unknown in the problem, and use flexible and effective methods to solve it, such as the two line segments required to appear in two triangles, then you should study whether the relationship between the two triangles is congruent or similar, and how to prove the congruence or similarity.

5) It is necessary to constantly summarize the practice of various geometric problems, such as the introduction of several auxiliary lines of trapezoids (a total of 7 kinds), how to solve the problems in general circles (often do radius), the proof of tangent lines (even radius, proof vertical), etc., as long as you continue to summarize, I believe you will have something to gain.

Intelligence in software.

Filter: Yes applied to.

Smart Objects. will appear in the Layers panel to which the Smart Object layer applies the Smart Filter.

below. Smart filters are non-destructive because they can be adjusted, removed, or hidden.

Concrete operation (CS6):

1. Open the "Filter" menu, click [Convert to Smart Filter], and click OK on the prompt page.

2. The layer properties are changed to "Smart Object Thumbnail", and after the "Wind" filter is processed, the filter will appear below the layer, and you can modify it by clicking on this filter directly.

Quite simply, because as soon as the normal filter function is executed, the original layer is changed to the effect of the filter, and if the effect is not satisfactory and wants to be restored, it can only be returned from the history to before the execution. The smart filter is like adding a style to a layer, in the layer panel, you can delete this filter, or re-modify the parameters of this filter, you can turn off the small eyes of the filter effect and display the original image, so it is very convenient to modify it again. That's the benefit of smart filters.

Hope it solves your problem.

Smart filters, just like adding styles to layers, in the layer panel, you can delete this filter, or re-modify the parameters of this filter, you can turn off the small eyes of the filter effect and display the original image, so it is easy to modify again. That's the benefit of smart filters. Hope it can help you solve your problem.

I drew with a paintbrush, not to mention the background, I clicked with a brush in the middle, the hardness of the brush was 20% (the hardness was adjusted by myself), and then I drew the same circle, freely transformed, flattened, elongated, overlapped on the circle, and then rotated into the current angle after copying the two.

For this, you don't need to do anything else, just use a brush and a blur tool, then adjust the thickness of the brush, then adjust the position, and finally use the blur tool to blur the corners and pull the tip.

Method: Create a new file and set the foreground and background colors to white and sky blue, respectively.

2.Then perform the filter Render clouds and see the effect! Isn't it like the sky?

There are many filters, and sometimes it may take several filters to be used together to produce a good artistic effect. The following is an example of making wood materials.

4.Create a new file, fill it with orange, and run the filter and add noise commands.

5.Then execute the Filter, Motion Blur command.

I have a case study tutorial in the filter section here.

Hope it works for you. You can refer to it, and then try it yourself, explore more, and toss it by yourself, o( o

Try more and find out. Bold use.

This is mainly on your own, and you will be proficient in using more, and you can check some tutorials on the Internet, which is very convenient.

Select the layer you want to process, click the menu in the filter, adjust the parameters, and you can preview the effect of the adjustment, if you are satisfied, you will be sure, and if the effect is not good, you will cancel.

Yes, it includes extract, liquify, pattern generator, pixelation, distortion, variegation, blur, rendering, brush stroke, texture, sketch, artistic effects, sharpening, stylizing, and many more.

Looking at life is like trying to make a reflection of a building in water, and then you have to think about the form of the reflection in reality. First of all, the reflection will be distorted, and it will be flipped 180 degrees with the real thing, and the other point is that the reflection will be dull, so as long as you are familiar with the various functions of Photoshop and the effects of filters, it is not difficult to make the desired effect.

This is experience, slowly accumulate, if you want to learn, look for tutorials on the Internet.

Once you know the effects of various filters, you can use them flexibly according to your needs in practice.

The filter should be kept moving

1.Before the operation, it should be done"History"panel, take a snapshot of history"When you want to revert a step. Straight back to that step!

is a repeat of the last filter"

shift+ctrl+f"is the dialog box that opens the last filter3The cloud filter is randomly distributed and different every time!

4.To build a layer for drawing, don't operate directly on the background layer, copy the layer!

Press the alt key on the keyboard, the cancel button will change to reset, and click reset to restore the initial state!

, make a copy first, and then copy out the layer! Don't touch the original!

This is the most basic common sense with PS!!
