The short answer

In Adobe Firefly, write the subject, place, light and mood in a short sentence and keep it consistent with the on-screen choices such as photo or art and style. In Generative Fill in Photoshop and similar apps, write only what you want to add and it blends with the surroundings. Check commercial-use terms on the official site.

How do you write an Adobe Firefly prompt?

Write the subject, place, light and mood in a short sentence and match it with the style choices on screen.

Firefly is a generative AI you ask with sentences. Rather than piling up tags like Stable Diffusion, a short sentence about what, where, and with what light and mood works better. The screen often offers choices such as photo or art, styles, colors and lighting, and the trick is to keep those choices consistent with the words in your prompt.

Choose an aspect ratio for the use
If there are style, color or light options, pick one that goes the same way as your prompt
Generate, then add or remove words based on the closest result

Rinka's tips

Firefly may accept several languages, but fine details sometimes come through better in English. Try both and compare
Lean either on the style options or on the style words in the prompt, not both in different directions
Put what must be kept, such as number of people or clothing colors, early in the sentence

How do you ask with Generative Fill in Photoshop?

Select the area you want to change and write only what you want to add there.

Generative Fill redraws only inside the selected area. You do not need to describe the whole picture; writing just what to add, such as "a small cat sleeping", lets it blend with the surrounding light and color. To remove something, select it and run it with the prompt empty; it often fills the area with background (behavior changes between versions).

Goal	How to select	Example wording
Add an object	The spot where it goes, a little larger	a small potted plant
Remove an object	Slightly larger than the object	(leave empty and run)
Extend the background	The empty area after enlarging the canvas	continue the library bookshelves
Change clothes or props	Only the part to change	a navy blue knit cardigan

What if Firefly does not give the picture you want? (Common mistakes and fixes)

Check the photo or art choice, overloaded wording and how you selected the area.

Problem	Cause	Fix
Meant an illustration but it looks like a photo	Content type leans to photo	Choose art and add illustration to the sentence
Generation is refused	Words that hit the usage guidelines	Rephrase and check the guidelines
Generative Fill looks pasted on	Selection too tight or description too long	Widen the selection a little, write only the thing to add
Faces or hands look odd	Person too small, complex hands	Show the person larger, use a pose with hands down
Mood changes every time	Different style choices each time	Use the same style and the same words

Can you use Firefly images commercially?

The conditions depend on the plan and terms, so check the official guidance before use.

Adobe presents Firefly as a service designed with commercial use in mind. However, the allowed uses, how generative credits work, and the information attached to generated images (such as content provenance records) can change. For work use, always check the current terms and plan. Do not make things that imitate real people or brands.
