Circle versus sphere
A sphere has volume, light and shadow; a circle is flat. If you want a ball, a planet or a glossy button, look under sphere. Come here for rings, discs, outlines and frames — shapes that sit behind or around something else.
What the files are used for
Hand-painted rings in ink or watercolour frame a quote, a price or a portrait with a human touch. Precise shapes — a clock face, a gear, a chemical ring — suit diagrams and technical slides. Soft colour splashes shaped into a disc make a background spot behind a product photo.
How to spot a good one
Zoom in on the curve: a clean circle has a smooth edge with no stair-stepping. For rings, the centre must be transparent rather than white, or the photo you place inside will be hidden. A brush-stroke ring should keep its dry-brush texture at the edge instead of a hard cut-out line.
