Good day, dear readers. It's been a long time since I wrote Photoshop tutorials. We need to fix it urgently. Today we’ll talk about one very simple thing that will be useful both for in or other elements for websites, and just for beautiful pictures and postcards.

Now you will learn how to draw a circle in Photoshop. It's very simple, fast and interesting. I'll also show you some fun options for making your own modern website content, social media group posts, or just postcards to send to your friends.

How to draw simple, even and beautiful circles

First of all, you need to open the Photoshop program. Do not forget that you have the opportunity to use the online version pixlr.com .

I never get tired of saying that you should not pay attention to simple (or other) options like Paint or some other nonsense. Learn to work in professional programs.

Now you will read an article about solving one problem, tomorrow about another, and in a year you will be able to carry out very healthy projects, even if you were not going to do it at all. Set yourself global goals. But, back to the main topic.

Create a new document.

Let's say it will be 500 x 500 pixels. It doesn't matter.

Now we find the ellipse tool in the control panel. If you can't find it right away, try holding down the mouse button on the menu buttons on the left for a few seconds. Perhaps the ellipse is hiding under the rectangle.

Now we draw a circle.

To make the circle even, hold down the shift button on your keyboard. It helps keep proportions.

Once you're done, an additional control panel will pop up. It duplicates the one at the top of the screen. You can work in any one you like more, it doesn't matter.

If you need to draw a figure of the desired diameter, change these values to the required parameters. Let it be 500. Look, if for some unknown reason only one indicator changes, do not forget to change the second one, otherwise you will draw an ellipse.

You can use a gradient, a pattern, or choose a single color. Open additional panels to expand your own possibilities.

Here you can also use different tricks: gradient, pattern, one color or no stroke.

If you want to change the line itself, look at the next column.

By the way, I completely forgot to say, if you are using a gradient fill, then try a radial effect so that the color comes from the center.

Another interesting effect

You can draw a circle directly on the picture or move it to the photo using the ctrl+c (copy) and ctrl+v (paste) buttons.

Now work with the opacity (in the panel on the left). Make sure that the layer you are working with is highlighted in the panel. In this case, an ellipse.

You can write some text in the circle.

If there are difficulties, you can download the psd layout of this picture, which you see in the screenshot above, and dig deeper into it. This makes learning more interesting. Take a look at my example for yourself. It's not difficult at all. ( DOWNLOAD >> )

There are layers: a photo of the savannah (background), a circle with a gradient (ellipse 1) and text. If you download this file, you can and should open it with photoshop, and then have fun as you like.

Or here is another picture you can download ( DOWNLOAD >> ).

To create it, in addition to the points that you already know about, on each layer I right-clicked and changed the blending options.

Download this layout and see for yourself, maybe you can significantly improve the result! Feel free to leave your options in the comments.

For those who want to understand

If you and my lessons, then I advise you to subscribe to my blog newsletter and receive information about fresh interesting publications directly to your mail. It's really convenient.

However, you must agree that you will have to wait a lot to learn and become a professional. Indeed, in addition to Photoshop, I talk about WordPress, how to sell and create websites, about plugins and negotiating with customers.

If you want to learn Photoshop in order to create websites, I can recommend two more options. First - lessons from here - " WEB DESIGN for beginners". I have already written about them in detail. In principle, if you want, you can learn a lot for free, in three days, which are provided as a test period. Very helpful and great.

However, it's cool if you're learning for yourself. If you are interested in earning big, then pay attention to Netology, namely this course - “ Web designer: effective site from idea to implementation »:

Yes, the price, of course, bites.

But what program and what teachers are waiting for you.

Here you have the director of Red Keds, and the creator of interfaces from Kaspersky Lab, and a bunch of famous and successful guys from companies with a worldwide reputation. Upon completion, you receive a diploma. This one is really worth it.

OK it's all over Now. Now you know the maximum and I can take my leave with peace of mind.

Good luck in job!

Dear beginner self-taught seamstresses, today I decided to write an article that will help us in the future to cut children's panama hats, adult beach hats, as well as a sun skirt, and of course flounces. As you guessed, we are talking about the ability to calculate the radius of a circle, and be able to draw it without a compass. Because it is quite possible that we will need to draw circles of a size for which compasses are not sold. And not everyone has a compass at home. So the agenda is:

Calculation of the radius of the circle, for panama, flounces and sun skirts.

Three ways to draw a circle without a compass.

HOW TO CALCULATE THE RADIUS OF A CIRCLE.

What is it for, this radius calculation? To draw a circle, we need to know radius this soma of the circle - that is, the distance from one leg of the compass to the other.

Let's say we need to draw the circumference of the bottom of a panama hat, and all we know is the girth of the baby's head. How wide should the legs of the compass be spread apart in order to end up with a circle that matches the size of the baby's head?

Or we need to draw the circumference of a sun skirt, knowing only that the circumference should ideally match the girth of our waist.

Now, to make everything very clear and understandable, Let's analyze 2 specific cases that are most often encountered in the work of seamstresses.

This is the calculation of the radius of the bottom of the panama hat. And the calculation of the radius on the pattern of the skirt-sun.

So let's go...

I beautifully painted this story in pictures right with the text-reasoning. To understand the whole sequence of the brain.)))

Means, to find out the radius - we need to divide our baby's head circumference by 6.28.

We take a mobile phone, find a calculator in it and divide our 42 cm head circumference by 6.28 - we get 6.68 cm = that is, 6 cm and 6 mm. This is the radius.

So, we need to push the legs of the compass to a distance of 6 cm 6 mm. And then the circle drawn by us will be equal to 42 cm - that is, it will lie flat on the child’s head (just don’t forget to hang it back by 1 cm for seam allowances).

Situation two - you need to draw the circumference of the skirt-sun. All we know is the waist circumference and the length of the skirt that we want to end up with.

There are 2 circles in the sun skirt drawing. Small (internal) should lie flat on our waist. That is, the length of this circumference should coincide with the circumference of the waist. The waist circumference is 70 cm, which means that the circumference should be 70 cm (well, perhaps, there are all sorts of centimeters back and forth in the form of an allowance for seams, or some other additional decoration in the form of a belt or yoke)

So we need to find out what radius to draw a circle so that the circle as a result turns out to be the length of these 70 cm we need.

In the picture below, I painted everything and how to calculate the radius of a small circle and then how to find out the radius of a large circle.

And when a small circle is drawn. All we need is to add the desired length of the skirt to the small radius - and we get a large radius for the large circumference of the edge of the skirt.

Here we are with the calculations. We will sew skirts and panama hats - I will send you to this article.

Now let's figure out how to draw a circle of any size without a compass.

HOW TO DRAW A CIRCLE WITHOUT A COMPASS.

Here below I have illustrated three ways with three pictures. I hope that everything is clearly drawn and spelled out.

Yes, this is a quick way - but you need to make sure that the pencils do not bow to the side. Change the angle of the pencil by changing the radius. Or it is necessary that one person evenly holds one pencil, and the other draws exactly perpendicularly with a second pencil.

In fact, the lower the thread is tied, the more accurate the circle will be. Therefore, some use small pins. The error when the pin is deflected to the side is small, and when sewing it can be neglected.

And yet, the surest way to draw an exact circle without a compass is with an ordinary ruler and pencil. Here's what it looks like:

And then in a circle, we move the centimeter (like the hour hand in a watch) and mark points at the same distance - that is, on the same number of the centimeter tape. Instead of tape, you can use twine with a mark on it - the main thing is to make sure that the twine does not stretch at all.

Well, that's all - another gap in knowledge has been eliminated - now you can swing at a sun skirt and a panama hat - we know how to calculate radii.

Drawing a circle is not the most common task in life. The more difficult it is to collect your thoughts when you have to draw a circle by hand, without a compass, stencil and other auxiliary devices. But no one is immune from such a need. Someone more often, and someone less often, to draw a circle without a compass happens to everyone. Schoolchildren and students who have forgotten the cooking at home. Parents of preschoolers who love to cut out "skirts" for cardboard dolls. Parents of schoolchildren receiving homework to make paper snowflakes. Housewives who regularly cover the bottom of the baking dish with suitable-sized parchment rounds.

At home, drawing an even circle is easy: you take a plate, saucer or glass, put it upside down on paper and draw around the contour. What about freehand drawing a perfect circle? I bet the circle will look more like an oval, an ellipse or a polygon, depending on the accuracy of your coordination of movements? In the end, this is already a challenge to yourself. Can I do such a trifle as draw a perfect circle without a compass?! We know you can. If you practice and use a few tricks to draw an even circle without a compass and / or stencil, freehand.

What is the easiest way to draw a circle without a compass?
Forgetfulness is not a problem if you can compensate for it with resourcefulness. Suppose you left your compasses at home, going to a geometry lesson (just on a topic related to circles) or a meeting (you urgently need to draw a visual pie chart). So that no one would guess about your absent-mindedness, put a deuce or reprimand, we offer you such simple ways to draw a circle without a compass:

In a pencil case (your own or a neighbor's desk), take a protractor. This drawing tool is famous for its versatility: it often replaces the ruler, and in the absence of a compass, it will also fulfill its task. Lay the protractor on the paper, placing the middle of its flat side at a point that will become the center of the future circle. Holding the protractor with your left hand, circle its rounded part with a pencil - this is half a circle. Now, being careful not to shift the center of the circle, rotate the protractor around the midpoint by about 90°. Trace the rounded side again in a new location. Rotate the protractor on the paper to complete the circle and bring the pencil line to a full circle. In principle, you can draw a circle from two semicircles, but not all protractors allow this, so the three-step method is considered the most versatile and accurate.
Even if there is no protractor nearby, you will have to break the reputation of a diligent student and use an object that is not approved by all teachers: a CD. It will be easier for a manager at a meeting, because there will probably be a disk with a presentation or photos from a recent corporate party at hand. Put the disk on paper and, pressing with your left hand, circle with a pencil with your right. If necessary, draw a small circle, circle the disc not from the outside, but along the inner hole.
Freehand drawing a circle for a diagram in an outline is as easy as shelling pears! To do this, take an ordinary glass (glass or plastic disposable - it does not matter), pretend that you want to wet your throat. Pour water into a glass (this will make it heavier and more stable), make sure the bottom is dry on the outside, and place it on a piece of paper in front of you on the table. Now casually, without attracting too much attention and without making sudden movements, outline the bottom of the glass on paper. Take another sip of water and place the glass away from the paper.

The compass, CD, and glass are the most common office items, but you can use other rounded outlines to draw a circle without a compass. The only drawback of this improvised method is in the limited radius of the resulting circles.

How to draw circles of different sizes without a compass?
To draw different circles smoothly and beautifully without a compass, you will have to do without auxiliary means: only paper, pencil and sleight of hand. But do not be alarmed: it is the hands that are able to draw a circle without a compass. You can use these methods in almost any situation:

To draw a small circle by hand, literally, place a sheet of paper on a table or other flat horizontal surface, and take the pencil in your right hand in a normal motion. Bring your hand with a pencil to the paper and, slightly lowering the lead onto the sheet, rest your little finger on the paper. The main condition: the little finger must press the sheet firmly against the table, but allow it to rotate around the axis, which has become the point of contact of the pads of your little finger. Put the writing tip of the pencil on paper and fix the position of the brush. With your other hand, rotate the sheet of paper around the little finger axis - and you will see how the stylus draws a perfect circle around it. A couple of tips: it is more convenient to use a soft pencil (B or 2B) and cut your nails short.
To draw an even circle with a larger diameter, you will not need other devices other than those listed in the previous paragraph. In the same way, take a pencil with a fairly soft lead with the fingers of your right hand. This time, bend the little finger and press it against the palm of your hand, as if you were gathering your fingers into a fist. Lean on the fold of the little finger and repeat the previous technique. Rotate the piece of paper at hand and still with the pencil at a comfortable speed to make a neat circle. Manicure in this case no longer plays a big role. You can draw a medium-sized circle without a compass separately, or you can draw around an already drawn small circle.
To draw a circle of even larger diameter, you can again get by with your own hands. The scheme of actions is repeated exactly until the moment of bending the fingers. But this time, rely not on the knuckles, but on the protruding part of the wrist. Outside there is a protruding bone, which will serve as an excellent support for the hand when drawing a circle. Hold the brush and pencil in it motionless, turning the sheet of paper on which an even circle of the desired size will appear.

The greatest difficulty of the methods described is to learn not to move the right hand holding the pencil. But you will probably manage after a few trainings and / or choose the speed of rotation of the sheet of paper under the stylus that suits you. In any case, artists admit that they use this particular technology when they need to draw a perfect circle by hand.

How to draw a large even circle without a compass?
It is a little easier for schoolchildren, artists and office workers: their circles fit on small paper. But tailors and cutters have to work with larger surfaces, and circles are no less common in their work. The bottoms of panamas and hats, the hems of sundresses and flared skirts - all these silhouettes are based on a circle. But this circle is often such that a compass commensurate with it simply does not exist. And this is how seamstresses came up with drawing circles without a compass:

First, determine which circle to draw by hand - that is, the radius of this circle. To do this, use a regular measuring tape to measure the desired area: waist circumference, head circumference, or another parameter. Let's say it's a 60cm waist.
The resulting number is the circumference. To find out the radius of a circle from the length, use the arithmetic formula: R= circumference/2∏. Accordingly, the radius of our circle will be equal to 60/2*3.14 = 60/6.28 ≈ 9.5(cm). This is the radius of the circle that we have to draw by hand.
Take two pencils of the same length. Tie them with a strong thread, the length of which, excluding knots (that is, the actual distance between the pencils with the thread stretched) is 9.5 cm. Place one pencil in the center of the future circle, and move the second one to the length of the thread.
Keeping the first pencil stationary, wrap the second in a circle, drawing a trace of the stylus on the paper and keeping the thread tension the same throughout the process of drawing the circle.
Thus, we imitated the principle of the compass, without having a compass to draw a large circle. The drawn circle is perfectly even and can be used for cutting the skirt belt.

To draw a complete skirt pattern, increase the radius (the length of the thread between the pencils) by the estimated length of the finished product and draw a second circle around the first. Before you is a blank for a pattern of a flared sun skirt, which you drew without the help of a compass and even a stencil.

How to draw a perfect circle without a compass
The main and, perhaps, the only drawback of all the above methods is the flaws in the circle being drawn. A circle drawn without a compass turns out to be approximately even, but not quite perfect, especially if you draw it in a hurry. There is a way to fix this nuisance. It will take a little longer, but you will be pleased with the result:

Take a piece of paper, a pencil and a ruler.
Decide what the radius of the future circle will be.
Put a dot on a sheet of paper and attach the mark "0" to it on the ruler.
Put the second dot on the paper right next to the number indicating the radius you have chosen.
Move the ruler, add "0" to the start point again, and put a second point according to the length of the radius.
Continue to put points at an equal distance from the center of the future circle.
As a result of these actions, you should get a circle drawn with a dotted line.
The more dots you put, the thicker the dotted line will be and the smaller the distance between its risks.
Connect the circle along the dotted line.

These are simple and affordable ways to draw a circle without a compass. Choose any of them or use the one that suits your circumstances. And remember that there are no hopeless situations - you can always figure out how to get out, how to solve a problem, or even draw an even circle by hand without a compass. Good luck, beautiful drawings and perfect graphs!

Any line, any stroke should express a certain shape in the drawing. Thanks to the strokes, lines are applied, which, in turn, create various figures. Figures of a flat form have a rectilinear surface, characterized by only two dimensions - length and width.

Square

A square is a regular polygon whose four sides are equal and all four angles are right. It is not difficult to draw a square with a pencil on a small sheet of paper, you just need to have a firm and confident hand. It is much more difficult to achieve confidence when drawing a square in a large drawing. In such a case, charcoal is considered the most suitable drawing tool. Having calculated the size of the square, you should depict one of its vertical sides. Now, from the top point of this straight line, it is required to draw a line perpendicular to it of exactly the same length. From the right point of this second line, draw a line perpendicular to it and parallel to the first. And, finally, it is required to unite the extreme points of two parallel lines.

The diagram below shows two squares, one larger (outer), the other smaller (inner). There are eight reference points on the symmetry axes of the large square. The vertices of the small square are at a distance of two-thirds of the diagonals of the large square from its center. The vertices of the small square are united by smooth arcs, due to which a circle is formed.

1. In order to draw a square, you need to know the length of its side.

2. From the top point of the vertical straight line, draw a line perpendicular to the first and equal in length to it.

3. Repeat the same action, finding another top point of the square.

4. Finish the square by connecting parallel lines.

Rectangle

A rectangle is a regular polygon whose opposite sides are equal and all angles are right. When creating a rectangle, you need to perform the same actions as when drawing a square, but taking into account the difference in aspect ratio.

Circle

When creating a drawing, an indispensable tool, no doubt, is a compass. In drawing, it is extremely important to learn how to draw without it. Until the skill of drawing a circle of the correct shape by hand has been formed, it is allowed to use some improvised means, for example, patterns or, as an impromptu compass, even an ordinary cord. You can also mark anchor points on two concentric squares to achieve your goal.

How to draw a circle by hand

In order to learn how to draw a circle by hand, you should start training by creating small circles with a radius of about 5 cm. As a rule, at first the figures are somewhat oval in shape, then, as you gain practical experience, the circles take on the correct shape. To draw larger circles, it is advisable to mark anchor points on two concentric squares or use a cord to make the task easier.

When creating drawings, it is not recommended to use a compass.

Practical advice: how to draw a circle with a cord

To develop the skill of creating the right large circle, it is useful to use a cord.

With one hand, hold the end of the cord at the point that will become the center of the circle. In your other hand, hold a piece of chalk and the other end of the cord at a distance that is equal to the radius of the circle.

2. Start drawing the arc from the point that will allow you to make the widest possible movement with the chalk.

3. To complete the circle, pass the hand holding the chalk under the hand holding the cord. At the same time, point your hand with chalk in the opposite direction.

4. Make sure that the cord is kept at the same distance from the center of the circle, achieve an exact connection between the beginning of the second semicircle and the end of the first.

The circle is also drawn using patterns. The simplest pattern can serve as the upper part of the glass.

You can build an oval in two ways, depending on the initially set parameters.

Method 2: when only the width of the oval is specified.

1 way to build an oval

You can download video lesson number 1 with the author's explanations: here.

The construction of an oval along two given axes of symmetry (larger and smaller) is performed in the following sequence:

1. We draw two axes of symmetry intersecting at right angles.
2. On the vertical axis, set aside the size of the width of the oval given to us CD(half size up and down from point ABOUT). On the horizontal axis, in the same way, we plot the length of the oval AB.

3. Connect the dots with a straight line WITH And IN.

4. From the center ABOUT connect the horizontal and vertical axis with a radius OV(marking a point e)
5. From point C we draw an arc with a radius Se to the intersection with the oblique line SW(marking a point f).

6. Plot between points f And B the inclined straight line is divided into two equal parts. For this, from the point f draw an arc with a radius fB, then from the point IN we draw an arc of the same radius, until it intersects with the arc constructed earlier.

7. We connect the points of intersection of the arcs. This line will be perpendicular to the segment fB and will cut it in half. We mark the points of intersection of the constructed line with the horizontal and vertical axes of symmetry ( l And k).

8.

Building a point m symmetrical point l.

9. Building a point n symmetrical point k.

10. From a point k draw a line through a point m. From a point n draw straight lines m And l.
11. Radius equal to distance kC from a point k draw an arc connecting the inclined lines emanating from the point k. Same radius from point n, as from the center, we draw an arc connecting the inclined lines emanating from the point n.
12. From dots m And l, as from the centers, we draw arcs with a radius mA and close the previously drawn arcs with them.

2 way to build an oval

The construction of an oval according to a given size of the larger axis of the oval is performed in the following sequence:

Axis AB divide into three equal parts ( AO 1,O 1 O 2 , About 2 V).

2.

Radius equal to distance O 1 O 2, from division points About 1 And About 2 draw circles. The intersection points of the circles are denoted as m And n.

3. Connect the dots m And n with dots About 1 And About 2 we get straight lines, which we extend to the intersection with circles. The resulting points ( 1,2,3 And 4 ) are the conjugation points of the arcs.

4. From points m And n, as from centers, radius Rmax equal to n 2 And m 3, draw the upper arc 1 2 and bottom arc 3 4 .

On this, the construction of the oval can be considered completed.

How to draw a circle without a compass

The ability to create a circle is not a life skill. And yet, sometimes it is necessary to know how to draw a circle when there is no compass or some kind of round object at hand.

Smooth circle - what to do if there is no compass

It is useful for everyone to know how to draw a circle without a compass. Usually this item is not available. In this situation, there may be a student who left the necessary tools for drawing at home, who should have a lesson on schedule. Or an adult who, for some reason, urgently needs to draw an even circle. What to do in these situations? For example, schoolchildren can replace a missing accessory with a protractor, which is often found in a pencil case. Just attach it to a sheet of paper, find the center on the straight part and put a dot. This place is considered the center of the circle. Then you need to circle the semicircle along the inside, turn the protractor 90 ° and carefully draw another third of the circle. After that, once again repeat the turn of the tool and finish drawing the rest of the figure.

If you have not been a schoolboy for a long time, which means that you do not have a pencil case with drawing tools at hand, then you can correct the situation with a CD. With it, it is easy to create a figure both small (if you circle the inside of the disk) and large (if you circle the outside of the disk). Office workers in a similar situation will be helped by a glass used for water. Just put it on paper and draw along the contour of the bottom with a pencil. Thus, we were convinced that it is possible to draw a circle without a compass, using improvised objects for this.

Ways to draw circles without using additional items

How to draw a circle if there are no drawing tools and other auxiliary things at hand? Everything is not as difficult as it seems at first glance. Place and fix one hand on the paper, while making sure that the little finger is the center of the planned circle. With your other hand, twist the sheet and see that you get an even circle. Draw along the resulting contour with a pencil. To draw a circle of a larger diameter, you need to bend your little finger, as if you are trying to make a fist. Further, the procedure is repeated, as with a smaller circle, twist the sheet and draw the borders of the circle. If you need to create a circle even more, then position your hand so that it touches the wrist bone to the sheet. Recommended for drawing circles, choose non-solid pencils.

These methods are considered easy and simple. They help out when there is no compass at hand. The main thing is to be able to hold your hand evenly and so that it does not move.

Draw a circle with a ruler

For those who have a ruler handy, the following way to create a circle will come in handy. You need to attach a ruler to a sheet of paper, at this point there will be the center of the circle. Put another mark next to the number indicating the radius. Then you need to put the third point, for this, slightly move the edge of the drawing tool, but so that the 0th mark remains in place, and put a notch above the second mark.

Repeat these steps to end up with a circle. It will be dotted. The more small dashes, the easier it is to draw an even solid line. This method is easy, but quite long.

The question is important not only for beginners, but sometimes for experienced artists. By understanding how to correctly draw a circle in perspective, we can draw a huge number of objects, not just pots and plates.
In general, a brief summary: usually we rarely see round objects frontally. For example, a plate like this

We see much less than this.

Therefore, we need to understand how to correctly depict a plate in a perspective horizontal plane. There is a simple scheme for this.

Most important on the left. We see ovals and a horizon line, with respect to which we usually draw all objects. At the level of the horizon line, the oval either turns into a line, or is very narrow. The higher or lower, the rounder the oval becomes, all the lines that are closer to us according to the law of perspective will be thicker, everything that is further away will be thinner. If the oval is far below the level of vision, it may become almost round. You can see this very clearly by taking a roll of tape, your ideal nature for practicing this skill. We raise the skein to eye level - ideally, we will see a rectangle, raise it higher and lower and immediately see clearly all the changes.
In the vertical plane, the story is exactly the same, only the diagram must be turned 90 degrees.

Thus, all plates and pots become subject to us, we look at the previous picture of the plate, taking into account new knowledge.

You can draw another oval to show the thickness of the plate, the final result depends on your powers of observation. The skill of drawing ovals trains very well in detailed drawing of simple objects, the same roll of adhesive tape, for example, is great at first.

There is another common mistake when drawing ovals. Many draw two arcs instead of an oval. This should not be allowed, even if your oval is very narrow, always draw fillets in the corners.

Over time, you will be great at finding perspective in almost any object.

Well, after the circles get bored, you can try to draw squares - the principle is the same. There is indeed a nuance with the vanishing point, but more on that another time.

I hope you will not have any more problems with the circle in perspective and your drawings will be correct and accurate. In addition to this post, you can also see
