In this series, Marc Gabbana walks you through his visual development process as he creates the TribalBot, a forest dwelling robotic vehicle. In this second volume, he begins by adding tone to his pen drawings using Adobe Photoshop. Marc demonstrates how to work with values and shading, and he shares his methodology for layer management. He also shows you which custom brushes he uses as he adds dimension to his designs. Through his gray scale paintings, Marc emphasizes how value, composition and lighting are all integral for creating drama and mood in a scene. Lastly, he shows you how to combine various tone images to create new and unexpected lighting scenarios. The final image is a fully painted TribalBot ready to pounce off the screen.

01Adding Tone to the 3/4 ViewFree

In this lesson, Marc evaluates and begins to further develop his ink over illustrations in Photoshop for his robot concept, focusing on principles of light and value to help describe the object and its silhouette. By understanding how light interacts with three-dimensional forms and working methodically from mid-tones to extremes, he shows how artists can render virtually anything they can imagine.

Duration: 16m 40s

02Adding Texture Strategically to the Image

In this lesson, Marc shows how he applies texture to his drawings. He emphasizes that every element helps establish visual hierarchy and guide the viewer’s eye. By developing a consistent personal set of techniques and studying master artists, illustrators can create compelling designs that clearly communicate their artistic vision.

03Adding Tone to the Foot

In this lesson, Marc focuses on developing the robot’s foot design. Using the same principles from earlier lessons, he shows how lighting and tonal values create clear, three-dimensional forms. By working systematically from mid-tones to shadows and highlights, and observing real-world lighting, Marc demonstrates how simple drawings can quickly become believable objects that communicate design intent effectively.

04Adding Tone to the Side Orthos

In this lesson, Marc begins to add value and tone to the side orthographic view, to help better inform the viewer. Continuing to work in value and tone, while utilizing additional tools in Photoshop, he quickly transforms flat line drawings into solid, three-dimensional designs.

054 Tone Studies - Lighting Scenarios

In this lesson, Marc explores four distinct lighting scenarios for his spider robot, using them as major tonal studies. By creating different moods and combining them with Photoshop layer masks, he demonstrates how to experiment and discover unexpected creative solutions. This approach is especially useful for developing rich, atmospheric sci-fi environments and finding the most compelling visual treatment for characters or creatures.

06Image Combinations - Using Layer Masks

In this lesson, Marc continues experimenting with different lighting combinations. He demonstrates painting using layer masks, a non-destructive way to explore and refine lighting in Photoshop. This approach allows Marc to quickly generate multiple atmospheric variations, discover unexpected lighting solutions, and make informed decisions about mood and focal points.

08Using Channels to Isolate the Line Drawing

In this lesson, Marc shows how to select and manage line work in an illustration. By converting line drawings into painted layers using channels, he gains greater flexibility to adjust line colors and keep elements cleanly separated. This method provides better control than traditional layer blending, making it a valuable technique for professional digital illustration.

09Adding Tone Under the Line Drawing Layer

In this lesson, Marc brings together techniques from earlier lessons to work on his final illustration. Keeping transparency, lighting, and value relationships in mind, he builds a foundational paintover that’s open to further design decisions. Working systematically, from broad values to refined details, and applying principles of contrast and plane changes, Marc shows how technical skill becomes second nature, allowing for limitless creative exploration.

  • I first met Marc at the Skywalker ranch; he had just finished work on George Lucas' Episode Two. Looking at Marc's drawing skill, technique and enthusiasm for image creation, I had no doubt he would continue on an ascending professional career. He later stopped by house, where I had more time to appreciate his creative skill. Now, years later I have the opportunity to reiterate my original assessment: Marc has an ongoing bright future as a premiere creative talent.
