Digital painting uses a tablet, stylus, and art software to create images with pixels instead of physical paint. It matters because artists can sketch, erase, recolor, resize, and revise quickly without damaging the original work. Beginners can explore portraits, landscapes, concept art, comics, and illustration while learning the same ideas used in traditional art, such as value, color, composition, and edges.
The main power of digital painting comes from layers, brushes, opacity, blending modes, and pressure sensitivity. Layers let you separate sketch, color, shadow, light, texture, and effects so each part can be edited on its own. A stylus can respond to pressure, tilt, and speed, making strokes feel more natural and expressive.
Working non-destructively means using editable layers, masks, and adjustment tools so you can experiment without permanently changing the base artwork.
Key Facts
- Canvas size is measured in pixels, such as 3000 px by 4500 px.
- Image resolution for print is often 300 ppi, while screen art may use 72 ppi to 144 ppi.
- Opacity controls transparency: 100% opacity is fully visible and 0% opacity is invisible.
- Brush size, hardness, opacity, flow, and texture change the look and feel of a digital stroke.
- Common layer order is sketch on top, clean line art above colors, shadows and highlights above base color.
- Non-destructive workflow uses separate layers, masks, adjustment layers, and saved versions instead of permanently erasing or flattening early.
Vocabulary
- Layer
- A layer is a separate transparent sheet in a digital file that can hold marks, colors, effects, or adjustments.
- Brush
- A brush is a software tool that creates strokes with settings such as size, shape, texture, opacity, and flow.
- Blending mode
- A blending mode is a layer setting that changes how the colors on one layer interact with the colors below it.
- Pressure sensitivity
- Pressure sensitivity is the tablet feature that changes stroke size, opacity, or other settings based on how hard the stylus is pressed.
- Layer mask
- A layer mask hides or reveals parts of a layer without deleting the original pixels.
Common Mistakes to Avoid
- Painting everything on one layer makes revisions difficult because the sketch, colors, shadows, and details become stuck together.
- Using too many brushes too soon slows learning because brush variety cannot replace strong values, shapes, edges, and color choices.
- Zooming in for the whole painting causes weak composition because small details may look neat while the full image becomes unbalanced.
- Erasing destructively on the main artwork removes information permanently, while masks allow you to hide areas and restore them later.
Practice Questions
- 1 A digital canvas is 2400 px wide and 3600 px tall. What is the aspect ratio in simplest form?
- 2 You paint a shadow layer at 40% opacity, then decide it should be half as strong. What opacity should you set it to?
- 3 You want to change the color of a character's shirt many times without repainting the whole figure. Explain which digital painting tools or layer choices would help and why.
