Adobe · Adobe Firefly web · Guidance v2, verified Sep 23, 2026 against 2 official sources
How to structure your prompt
A concise, specific visual description of at least three words in simple, direct language: lead with the subject, then distinctive descriptors, setting, composition, lighting, style and mood. Comma-separated descriptors are fine. Add feeling words that match the intended emotion (for example gentle and playful, or powerful and uplifting). Do not start with conversational create or generate phrasing. Choose aspect ratio, content type and other available controls in Adobe Firefly separately.
Length and syntax
Up to 2,000 characters. Longer prompts are not better if the extra words do not change what appears on screen.
Plain descriptive phrases, commas allowed between descriptors. No parameter flags.
