Three kinds of jewellery lighting effects
Once you’ve nailed down the shape and design of your jewels in flat colour, it’s time to add light. Use a soft, Round brush to paint in the absorbed light. It’s like a soft glow that emanates from the middle of the jewel. Paint it first because the highlights always go over it. Next up are the subsurface highlights. Gemstones are translucent, so you can see beneath the surface to the gem cuts and the object they’re embedded in. When light passes through and hits the surface on the other side, you get highlights in a colour similar to your stone. The regular highlights are more straightforward. As always, the highlight will fall on the precise point where your line of sight would bounce up to the light source, as if it were a pen laser. These highlights will be in the colour of the light source.
Use elements to direct, or block, the path of the viewer’s eye. Point your elements towards your focal area with dynamic lines and perspective (1) and block the flow of view with parallel lines, to direct it back from wandering away (2). In creating cinematic key art you have to use the whole composition. Frame it to consciously direct the viewer’s eye and tell your story in the best possible way.
