Materials such as a clothcovered padded seat not only require texture to make them look convincing, but an understanding of their physical structures and how light interacts with them. Before I start, I search the internet for images to gain an idea of the characteristics of a padded seat. For instance, a padded seat usually has rounded edges, and the silhouette of the padding should reflect that.
Additionally, the fabric or leather is usually stretched over the back and/or bottom of the chair, making tiny bunches in the drapery where the tension is strongest. It’s the attention to such details that would make the rendering more convincing. I want a lighting condition that’s high-key, so that the materials can be depicted with clarity. To that end, I chose to position the seat in front of a wide window.
First, I need to sketch the seat in perspective. I use simple, one-point perspective to establish that. For clean-looking objects such as these, I use Photoshop’s Pen tool for more control over my edges. You can erase some edges with an Airbrush for soft edges, but in this instance, it’s not needed. After that, it’s a matter of rendering the material and overlaying a material texture (on Soft Light mode) as needed.
Use a broad Airbrush and lay down areas of light and shadows. The bright backlighting creates a semblance of rim light over the chair.
