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
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.
Duration: 6m 56s
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.
Duration: 8m 15s
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.
Duration: 7m 22s
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.
Duration: 2m 43s
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.
Duration: 16m 14s
In this lesson, Marc showcases his final line drawing. By combining scanning technology with Photoshop's adjustment tools, he shows how artists can preserve the organic quality of hand-drawn work while achieving the clean, crisp results necessary for professional illustration and publishing purposes.
Duration: 28s
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.
Duration: 1m 4s
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.
Duration: 49m 42s
In this lesson, Marc focuses on the finer details of his illustration, drawing on his understanding of light, form, and materials. Through consistent practice and a deep grasp of how light interacts with surfaces, artists can work intuitively and efficiently, creating illustrations where technical skill fades into the background and the design itself takes center stage.
Duration: 1h 26m 55s
In this lesson, Marc demonstrates how subtle enhancements, like texture, selective glows, and strategic highlights, can significantly elevate a design. By balancing mechanical hardness with organic softness and keeping a clear focal point, he shows how to create a compelling and cohesive final piece.
Duration: 7m 19s
In this final lesson, Marc revisits his Photoshop layers, showing how careful layer management and the addition of tone and shading can bring a simple line drawing to life, while keeping compositions strong with clear silhouettes and well placed backgrounds.
Duration: 1m 44s
