How to Get Great Results
- Step 1
Lock composition with camera cues
Specify lens and shot type (85mm close‑up, 50mm medium, 35mm environmental) and include depth of field to stabilize framing.
- Step 2
Define lighting and palette
Choose a filmic setup—Rembrandt key, soft window light, golden hour rim—and call out a restrained color grade to avoid oversaturation.
- Step 3
Describe materials precisely
Use concrete surface language (brushed steel, aged leather, embroidered velvet) to encourage refined micro‑detail.
- Step 4
Keep prompts focused
Two concise sentences outperform long adjective chains. Iterate with one or two changes per run.
