How Do You Turn a Photo into AI Art Without Losing the Subject?

You want an illustration of your café, but the generated version replaces its distinctive windows with a generic storefront. The image is attractive; it is no longer your café. How do you change the medium without losing the reason for using the photograph?

Choose what must remain recognizable before choosing the style. For a building, that might be the entrance, window arrangement, and awning. For a pet, it might be the ears, markings, and silhouette. The model needs more direction than “turn this into art.”

Make a short preservation brief

Look at the source and identify three to five defining features. Separate those from details that can be simplified. In a café illustration, you might preserve three arched windows and a red awning while allowing paving stones and distant pedestrians to become broad shapes.

Use AI Image Editor when your photograph should guide the result. AI Illustration Generator is more suitable when you want a new imagined scene from text.

Work through a café illustration in DrawNew

Open the creator, choose Nano Banana Pro, select editing mode, and upload a clear photograph of the façade. Choose a supported ratio close to the source so that a new crop does not compete with the style change. Review the credit estimate, then adapt this brief:

Turn the uploaded café photograph into a gouache-style illustration. Preserve the three arched windows, central entrance, red awning, building proportions, and camera viewpoint. Simplify the pavement and distant background into broad painted shapes. Use opaque color, soft brush edges, and a warm restrained palette. Keep the building recognizable. Do not add windows, move the door, or invent signs or lettering.

Those architectural details are an example; replace them with what is actually in your photo. The prompt is not a tested before-and-after demonstration.

Choose the medium by the detail you can afford to lose

Desired result	Describe this	Expect to review this
Watercolor travel sketch	Translucent washes, paper texture, selective loose edges	Whether delicate markings and small details disappear
Gouache editorial artwork	Opaque color, broad shapes, soft painted edges	Whether simplification changes the subject's proportions
Flat illustration	Limited palette, clear silhouette, fewer internal details	Whether the remaining features are enough for recognition

For a pet portrait, a flat illustration may need the exact pattern of a patch around one eye even if the fur becomes a solid shape. “More detail” is not always the answer; the right detail matters.

If it still looks like a photograph

Clarify which structures should become painted shapes: broad shadow areas, simplified foliage, and softer edge transitions. Remove conflicting requests such as “keep every photographic detail” when your goal is a simplified illustration.

If it changes too much, go in the other direction. Reduce abstraction, return to the original source, and name the feature that was lost. “Keep the three windows in their original positions” gives you a clearer experiment than “more accurate.”

Finish the artwork for its destination

For a postcard, test the final crop and leave a planned area for the place name. Add exact lettering separately if it matters; the text troubleshooting article explains why more regeneration is not always the best typography workflow.

For a social series, save the accepted style paragraph and reuse it with new source photographs. Compare the set for palette and edge treatment, while checking each subject independently. If you only wanted a photographic color treatment, use photo style transfer instead of asking for a new medium.
