How to Do Vector Digital Art? Paint Tool Sai

Then, you simply scanned or took a picture of your hand-drawn line art with your smartphone and, you go to colour information technology to detect that it just doesn't look every bit ready to color as the original. At times like these, it'south best to extract your line work and convert it into something more suited for digital coloring. You can exercise this by using the Convert Brightness to Opacity part in Prune Studio Paint and SAI or the Blastoff Channel role in Photoshop.

Adjusting the Image Color

Using our graphics software of choice, we'll begin by opening the scanned or photo image of our illustration.

Even though the original paradigm is black lines on white newspaper, the imported prototype ends upwardly with either a gray tone to it, or the lines aren't as strong equally in the original. To fix this issue, we will arrange the image and so that the background is completely white and the lines are solid and articulate. The method we volition apply to achieve this depends on the graphics software we want to utilise.

Photoshop & Clip Studio Pigment

First, we'll adjust the colour using an adjustment layer (Tonal Correction layer).

● Effulgence/Dissimilarity

Use Brightness/Contrast to burnish the overall image.

In Photoshop:

Layer menu > New Adjustment Layer > Brightness/Contrast

In Clip Studio Paint:

Layer menu > New Correction Layer > Brightness/Dissimilarity

From the displayed carte, apply the Brightness slider to make the paper background as white as possible without losing too much line art detail.

● Level Correction

Adjacent, utilize Level Correction to make the lines more distinct.

In Photoshop:

Layer bill of fare > New Adjustment Layer > Levels

In Clip Studio Paint:

Layer bill of fare > New Correction Layer > Level Correction

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

In one case complete, the adjustments will be created in the course of an aligning layer (Tonal Correction layer). If you aren't quite satisfied with the results, double click the adjustment layer icon to display the carte du jour once more and readjust your settings.

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

Simply in instance, I recommend saving your file in one case before 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, adjust the Effulgence slider so that the paper appears white. Make certain that sparse lines do non disappear or become too thin while adjusting. Once satisfied, click OK.

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

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

Completing the color adjustments

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

In order to make the coloring stride go more than hands, we volition "extract" the line work past transforming the white background into a transparent background.

Extracting Line Art: Clip Studio Pigment & SAI

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

Clip Studio Paint:

Edit card > Convert brightness to opacity

SAI:

Layer menu > Luminance to Transparency

With this, the line art has been extracted!

Note:
Later using Clip Studio Paint'south Catechumen brightness to opacity, a transparent checky pattern will appear.
Select the Layer carte > New Layer > Paper to create a new paper layer over the transparent pattern.

Extracting Line Art: Photoshop

Using Blastoff Channel, we will turn the white transparent.

The Alpha Aqueduct function can excerpt transparency, uses selections as a mask for editing, and has a saving ability.

Note: The Alpha Channel feature cannot exist used in Photoshop Elements.

(i) Select the Selection carte du jour > Load Selection

(ii) Select the Alpha Aqueduct we used earlier from Channels

(iii) Cheque Invert and click OK

● Creating line art

Next, we'll make a new layer based on the line art.
