How to Get Great Results
- Step 1
Compose with photographic cues
State lens/shot (35mm wide, 50mm medium) and lighting (golden hour, overcast) to stabilize framing and mood.
- Step 2
Guide palette and weather
Use concise descriptors like 'misty dawn', 'stormy teal‑orange', 'night city neon' to push atmosphere without clutter.
- Step 3
Describe materials and scale
For sci‑fi, reference materials (brushed alloy, glass, concrete) and scale cues (towering spires, kilometer‑wide ring).
- Step 4
Iterate in small steps
Adjust one variable per pass—lighting, palette, or foreground elements—to converge quickly while keeping clarity.
