How to clear a scanned drawing (Lesson II)


1) We need to make the picture white and neat. To do this, go to Image> Adjustments> Brightness / Contrast.

Let's increase the brightness so that:

1 - make the background pure white.

2 - remove traces of gum, scratches on paper from a pencil and stains.

Move the Brightness cursor until you have the desired effect. However, do not exaggerate! I set the parameter to +28.

In the image, I emphasized what the flaws were, and how the pattern changed after applying contrast (this is especially evident on the shoulder and near the nose).

2) You most likely noticed that after increasing the brightness, the outline of our picture also became lighter. Therefore, in order to make the outline darker, go to Image> Adjustments> Auto Levels.

Here's how our drawing looks before and after applying Auto Levels.

3) Now you need to make the picture saturated in order to remove the small colored spots that appear during scanning. Go to Adjustments> Desaturate.

After that we need to add some blur to make the outline smoother: Filter> Blur> Blur

Here, our drawing is before and after the blur.

Editing is not so obvious, but all of these steps are very useful and necessary.

After correction, our drawing looks like this.

Pretty clear, right?

Now we will try to make some adjustments to the picture where there are fuzzy or ugly lines. For example, the fuzzy circumference of Ruri's hairpin or a terrible mess in the hair.

We will use the new features and tools of Photoshop, so you need to know the main windows.

The workplace should look something like the picture. I noted the most important tools that come in handy for this lesson. The most important thing in Photoshop is to know how to use ”Layers ”. One tip: use as many layers as needed. Each file can contain many layers, since they work like transparent sheets of paper to add details to the picture without editing. You can add or remove a layer, make it transparent or opaque. You can also change their order. Create copies, or merge everything into one layer.

Let's edit the studs

First of all, create a new layer.

Select the Ellipse Tool (to create perfect circles), to bring up a drop-down menu, right-click on the icon.

Go to the top menu of the Ellipse Tool and click where marked in the picture (Paths):

Select the circle of the stud, which we will correct. In order for you to understand how to create circles, I dashed a non-existent square on top of the hairpin. Now place the mouse cursor in the upper left corner of this square, and while holding the SHIFT button and the left mouse button, drag the cursor to the lower right corner of the square.

Now go to the tab "Paths " (Paths)

To make the circle visible, select a brush in the toolbar.

Follow these steps:

Now we see a clear outline of the circle!

We no longer need the path of the circle, so we delete it. Left-click on a blank field. Or you can drag the path icon to the trash at the bottom of the window:

Now we have two hairpin circles: one that we drew on paper and one that we just created. Our goal is to preserve the circle we just created and remove the old one. And this is quite easy to do, since they are on different layers.

The scanned image is on the background layer, by default. You cannot use an elastic band on the background layer, so for further work we need to transfer it to a regular layer, and for this we just need to rename it.

We remove the gaps.

In order to remove the gaps from the gum, you need to create a new layer and fill it with white.

Set the color to white.

Create a new layer “Layer 2” and fill it with white.

Set the layer "Layer 2" to the lower level.

Rename the layers.

It is important to give names to the layers, since when there are many of them (for example, 20 layers) it will be easier to quickly find the required layer. Give simple and clear names, so that it would be easier to remember what is on this layer.

Renaming a layer is simple, double-click on its name (in the layers menu, of course) and type in what you need.

How to merge layers

Make the white layer invisible simply by clicking on the eye icon, since we need to merge the remaining layers without affecting it. It is very important that the outline of our drawing is on the same layer, and the circumference of the stud is an integral part of the outline!

Now combine Layer> Merge Visible.

When combining two or more layers, the result is the name of the layer that stood above. Let's rename the layer that is born from the merge on Lineart.

How to fix an outline

Now we need to fix the contour (for example, fuzzy or broken lines).

Remaining on the “Lineart” layer, select an eraser with hard edges and the required size (I chose an eraser with hard edges and a size of 13 pixels, if necessary, I will use a smaller size).

We remove broken and bold lines, making them straight and sharp.

Use a smaller eraser (5-3 pixels) if necessary. You may need to remove too much or completely redo the line.

Now select the brush, setting the shape and size so that it looks like the original contour, and then draw a line.

If you don’t like any lines, remake them in the same way.

Recent adjustments

There may be unwanted dots on the scanned image that can be removed with an eraser.

Now our circuit is ready!

Contour separation method

Turn off the white background layer by clicking on the eye icon. Go to the “Lineart” layer and select the ”Magic wand tool ” (magic wand tool.).

And then with the help of a magic wand (with the settings marked in the picture), click on the black color of the “Lineart” layer (for example, where am I). Be careful and click on the black color!

Go to the Channels tab. . Now click on the circle indicated by the dotted line (Load channel as selection). Then press the DEL button on the keyboard.

Voila! You have separated the outline from the background! Press CTRL + D to admire the result of XD

If transparency prevents you from viewing the outline, you can again click on the eye icon next to the white background layer and make it visible.

In the next lesson, we’ll talk about anime-style coloring without applying shadows and shades. I decided to show you this method, because not everyone has a tablet, and so your drawings will look very beautiful
