You will need the following in order to complete this tutorial:
a sheet of watercolor paper

a small jar with water
any set of watercolor paints
a scanner that has the ability to scan A4-size paper
1.How to Create the Strokes on Watercolor Paper
Prepare your brush, paper, and paints, and then pour the water into the jar.
Put a small amount of water on the paper with your brush.
Start adding paint to the water on the paper using the edge of your brush.
Continue to add paint until your stroke looks like the picture below.
Now let’s create a second watercolor stroke. Draw a long stroke with one horizontal movement.
To create the last one, use sharp movements by holding the brush by the tip.
Now we need to wait a while for it all to dry.
2. How to Scan the Paper
We need to prepare the scanner glass to avoid stains or unwanted elements on your brushes. You can use a wet wipe to clean the glass.
Once you have cleaned the scanner glass, put your paper inside the scanner.
Set the following settings in your scanner preferences: A4 paper size, 300 dpi. Then start scanning. The color of our scanned paper can be different from the color of our strokes, but it is much more important for us to preserve the structure.
3.How to Create the Strokes on Watercolor Paper
Use Control-N to create a new document and use the following settings: 1500 x 1000 px; 300 dpi.
Go to File > Place and put your scanned paper inside the document.
Resize your scanned paper to the borders of the document, so one of the brushes will be placed in the center, and click Enter.
Select your layer and use the Shift-Control-Alt-B key combination and set the following settings: Reds: 40%; Yellows: 60%; Greens: 40%; Cyans: -25%; Blues: -25%; Magentas: 80%.
Go to Image > Adjustments > Brightness/Contrast and use the following settings: Brightness: 35; Contrast: 25.
Right-click on the layer and then select Duplicate Layer.
Create two more duplicates of your layer using Right-click > Duplicate.
Make all scan layers as Invisible except the first.
Select your first layer, go to Select > Color Range, and click on the white area on your image. Click OK.
Now the white background of your image is selected. Delete it using the Delete button.
Then click on any part of your document to Deselect the previous selection and select your stroke using the Lasso Tool.
Go to Edit > Define Brush Preset, select any name you want to use for your brush, and hit the OK button.
Our first brush is almost ready to use. Select Brush Instrument and then select your watercolor stoke. After that, hit the Brush Settings icon.
Put tickson Shape Dynamics, Color Dynamics, and Transfer.
Go to the Shape Dynamics panel and set Size Jitter to 90% and Angle Jitter to 50%.
Go to the Transfer panel and set Opacity Jitter to 25%.
Now our brush will create realistic looking washes:
Now we need to cut the second stroke from the background as we did before, and after that go to Edit > Define Brush Preset and createWatercolor Brush 02.
Open the brush settings and go to Dual Brush andthenselect your first brush. Set Mode to Multiply; Size to 450 px; Spacing to 72%.
This way, we can combine the brushes and add grunge scrapes to our brush texture.
Now we need to cut the second stroke from the background as we did before, and after that go to Edit > Define Brush Preset and createWatercolor Brush 03.
Open the brush settings and go to Shape Dynamics, and set Size Jitter to 100% and Angle Jitter to 75%.
With these brush settings, we can create ink splashes.
Awesome Work, You’re Now Done!
Using these methods, we can create different types of watercolor brushes for Photoshop using a scanner, watercolor paper, and paints.
