How To Get Sharp Lines Painting Auto Graphics

So, you lot just scanned or took a moving picture of your mitt-drawn line art with your smartphone and, you go to color it to find that it just doesn't wait as gear up to color every bit the original. At times like these, information technology's best to extract your line work and convert it into something more than suited for digital coloring. You can practise this by using the Convert Effulgence to Opacity function in Prune Studio Pigment and SAI or the Alpha Channel function in Photoshop.

Adjusting the Image Color

Using our graphics software of choice, nosotros'll brainstorm past opening the scanned or photo image of our analogy.

Even though the original prototype is blackness lines on white paper, the imported prototype ends upwardly with either a gray tone to it, or the lines aren't as potent every bit in the original. To prepare this consequence, we will arrange the paradigm so that the background is completely white and the lines are solid and clear. The method we will utilize to accomplish this depends on the graphics software nosotros want to utilise.

Photoshop & Clip Studio Pigment

Starting time, nosotros'll adjust the color using an adjustment layer (Tonal Correction layer).

● Brightness/Contrast

Use Brightness/Dissimilarity to brighten the overall image.

In Photoshop:

Layer card > New Adjustment Layer > Brightness/Contrast

In Prune Studio Paint:

Layer bill of fare > New Correction Layer > Brightness/Contrast

From the displayed card, use the Brightness slider to brand the paper groundwork as white every bit possible without losing too much line art particular.

● Level Correction

Adjacent, use Level Correction to make the lines more than distinct.

In Photoshop:

Layer menu > New Adjustment Layer > Levels

In Prune Studio Paint:

Layer menu > New Correction Layer > Level Correction

From the displayed menu, operate the triangle nodes at the bottom of the graph by dragging them right or left as needed. This allows you to whiten the color and shadows of the paper, as well as thicken and darken the line piece of work.

Once complete, the adjustments volition be created in the form of an aligning layer (Tonal Correction layer). If you lot aren't quite satisfied with the results, double click the adjustment layer icon to display the bill of fare once again and readjust your settings.

Lastly, select the Layer bill of fare > Flatten image and the line fine art layer will merge with the adjustment layer (Tonal Correction layer).

Merely in instance, I recommend saving your file in one case earlier merging.

Adjusting the Image Colour: Pigment Tool SAI

For SAI, select and set the Filter menu > Brightness/Contrast settings.

In the Brightness and Contrast dialog, adapt the Brightness slider then that the paper appears white. Make sure that thin lines do not disappear or go too thin while adjusting. Once satisfied, click OK.

Select the [Filter] menu > [Brightness/Contrast] again.

This time, adjust the [Dissimilarity] and [Brightness] sliders to darken the lines. Take intendance that lines don't become too thick or extend past your original line work.

Completing the colour adjustments

Compared to the original image, we have created much nicer looking line art, dark lines on a white background.

In order to make the coloring step go more easily, nosotros volition "extract" the line piece of work past transforming the white groundwork into a transparent groundwork.

Extracting Line Fine art: Clip Studio Pigment & SAI

We will plough the white transparent past using "convert brightness to opacity." Select the following commands to do this.

Prune Studio Paint:

Edit carte > Catechumen brightness to opacity

SAI:

Layer menu > Luminance to Transparency

With this, the line fine art has been extracted!

Annotation:
After using Clip Studio Paint'due south Convert brightness to opacity, a transparent checkered pattern will appear.
Select the Layer menu > New Layer > Paper to create a new paper layer over the transparent pattern.
