Please can you explain the theory behind lost and found edges
Ally Demoray, US
An edge can disappear when a foreground object has the same value as the background, and can become sharper by strengthening the contrast between those two values. On an illustration we can play with different lighting scenarios and create parts with disappearing edges in the shadows or lights.
It’s always useful to vary your edges between soft and hard. This helps to direct the focus of your image, and makes it more interesting and painterly. You can define differences between forms with hard edges more clearly and you can create a resting point for your viewer by applying soft edges. The trick is to find a balance that supports the story.
Sometimes it’s enough to paint only a small part of an edge and leave the rest to dissolve into the background. The most important thing is to describe the dynamics and direction of the edge, but we can leave the rest to the viewer’s imagination.
The face or the cape of this character is a great example for this. Because I’ve already painted one side of the character’s face, it’s fine to leave the other half fully in the shadows – the viewer’s imagination fills in the missing details. The same thing happens with the cape on the right side. It’s not necessary to depict its silhouette all the way. Instead, painting the bottom edge and hinting at the shoulder part is enough to describe the whole form.
I want to show a bounty hunter blending into the shadows, so applying lost edges around the character is a great choice to strengthen his personality visually.
