Introduction to Digital Illustration: Tools and Techniques

Digital illustration has become a core discipline within the broader graphic design, animation and concept art fields. Illustrators leverage digital software and tools to create vibrant imagery for books, editorial, websites, advertisements, concept art, game assets and much more.

This guide will provide an overview of digital illustration covering fundamental concepts, essential tools of the trade, techniques, best practices and resources to help beginners get started. Let’s dive in!

Digital Illustration Fundamentals

Before jumping into tools and techniques, understanding foundational concepts and theory is key:

Raster vs Vector Graphics

Raster graphics are comprised of pixel grids. Vector graphics use mathematically defined shapes. Raster works for photos. Vector is better for logos, animation and adjustable print output.

Color Theory

Understand color harmonies, blending modes and palettes. Using color purposefully enhances illustrations stylistically and psychologically.

Composition and Layout

Arrange graphic elements strategically based on principles like the rule of thirds, leading lines, framing and balancing elements. Direct the viewer’s eye.

Shape Language and Contrast

Visually communicate through deliberate shapes, silhouettes and sizes. Establish contrast between elements.

Concept Art Principles

Methods for effective visual storytelling and worldbuilding. Usually involves character, costume and environment design.

Drawing Perspective and Dimension

Critical for conveying depth. Linear perspective, atmospheric perspective, foreshortening and conveying light/shadows make illustrations appear dimensional.

Art History

Studying different artistic eras and movements like Baroque, Art Nouveau, Propaganda, Pop Art, etc provides inspiration.

Essential Digital Illustration Tools

These core software tools form the standard digital illustration toolkit:

Adobe Illustrator

Vector illustration app for logos, web/UI design, comics, technical drawings. Provides precision and scalability.

Adobe Photoshop

Raster painting and photo manipulation app. Great for texturing, effects and precision masking.


Top illustration and painting app made for iPad + Apple Pencil. Very intuitive for freehand drawing.

Adobe Fresco

iPad painting app mimicking real artistic media like oils and watercolors via touch and Apple Pencil.

Top Techniques and Best Practices

Applying these methods will take your digital illustrations to the next level:

Thumbnail Sketches

Rough out multiple composition options quickly. Refine the best thumbnails into final pieces.

Efficient Layers and Groups

Use layers to isolate elements so they remain editable. Groups help organize more complex documents.

Custom Brushes

Make and import custom brushes to speed up repetitive tasks or emulate natural media effects.

Non-Destructive Editing

Utilize adjustment layers, layer styles, masks and smart objects to apply changes non-destructively for flexibility.

Reference and Draw From Life

Use photo reference and study the world around you closely to illustrate based on realistic forms, perspective and lighting.

Color Pick From Photos

Sample colors directly from photos to coordinating palettes matching real-world scenes and objects.

Create 3D Renders as Guides

Model simple shapes and environments in 3D to use as an underpainting guide for perspective and lighting.

Mix Vector With Raster

Design key elements in vector then add raster textures and painted effects for efficiency and artistic style.

Save Production Assets

Maintain libraries of brushes, colors, materials and common elements to reuse on projects for consistent branding and efficiency.

Learn Efficient Shortcuts

Customize hotkeys in your apps to speed up tedious tasks and streamline your creative workflow.
