How to turn a hand drawn sketch into digital art

In this guide, I show you the process of turning a pen drawn sketch into digital artwork. You’ll need two programs to follow this guide: Adobe Photoshop and Adobe Illustrator. I use Photoshop to adjust the tones in the image and Illustrator to convert the flat image into a vector. A vector is useful because then the image can be scaled to almost any size and it keeps the clarity.

The Tools

Either: Digital Camera / Smartphone with a Camera / Scanner
Adobe Illustrator & Adobe Photoshop

Find a well-lit area (natural light is best) with a flat surface to lay your work onto. I take my photos without a tripod, but it can be better to use one to steady the camera. If you don’t plan to use a tripod, I recommend taking a few photos, just to make sure that one is perfectly focused.

Load your photos onto your computer. I like to prepare the photo first in Photoshop before opening it in Illustrator. Open the photo you wish to use in Photoshop.

Prepare in Photoshop

1-2 The adjustments needed will depend on the photo, this photo came out blue and so I need to turn the blue white. First, I add an Exposure adjustment layer. I then 3 increase the Exposure, 4 reduce the Offset, and 5 increase the Gamma Correction.

Turn the background white

6-7 Add another adjustment layer, this time, select Black & White.

Change the writing to black

Save your image, a JPG or PNG are fine (Click File in the top menu, and choose Save As).

Open the edited image in Illustrator. Now you are going to convert the flat image into a vector.

8 First, click the little arrow next to “Live Trace” then 9 select from the drop down menu the “Photo High Fidelity” option. I like this option as it can retain the texture in the drawing.

Expand vector

10 Click the “Expand” button. The sketch will turn blue because the software is letting you know that the drawing is selected.
You can also see blue specs outside of the text, which is probably dust the camera has picked up.

Double click on the white space around the words, and press the delete key on your keyboard to remove the white background.

guide-8

11 Click and drag your cursor to select the dots around the words, delete these (or you can keep these if you wish to have a rougher looking design).

To see where there may be extra specks hiding, create a color block, and place the layer behind your artwork. To do this, 12 click the color block and choose your color. 13 Click the Rectangle Tool, click and drag, to create a colored background. Lock the layer, by clicking the padlock symbol next to your new color block layer. Now select the Selection Tool again (the black arrow).

guide-11

Select and delete these areas. Exit your group, by double clicking on the area surrounding your artboard. Unlock the colored layer and delete it. Don’t worry about the thin white area around the words; we can fix that in Photoshop.

Once you’re happy, go to 14 “File”, and click 15 “Save As”, save your graphic as an EPS file.

Close Illustrator and open Photoshop.

I now set the size I’d like piece to be, click 16 “File” and choose “New”.

29 Drag the arrow below the white section towards the black section. The further you drag it the rougher your typography will be. 30 Click OK to apply.

Finished digital artwork

Save your image, I save it as a PSD and a JPG. That way, if I wish to edit it again in the future I can edit the artwork with the PSD file. When you save the JPG, make sure you choose the highest quality.

Now you have your digital artwork!
