Dark artwork often fails quietly: detail visible on the artist’s monitor disappears after compression or at a lower phone brightness. A small verification routine catches most problems before export.
Keep a shadow ladder
Include several near-black values in the working file and confirm that adjacent bands remain distinguishable. If two steps merge too easily, simplify the local texture or raise the darker step slightly.
Watch long gradients
Smoke, glow and empty skies reveal tonal banding. Gentle texture can mask visible steps, but it should not become noise. Compare the compressed output at full screen rather than judging only a zoomed desktop crop.
Export with intent
Use a lossless master and a web-ready derivative. Do not repeatedly re-save the same compressed file. Apple recommends delivering artwork at suitable scale and testing on actual devices.
- Retain the master color profile.
- Preview the exported file, not only the source document.
- Avoid resampling the same derivative more than once.
