Use outpainting to extend a frame, image fusion to bring multiple references into a new composition, and a focused text instruction to refine the selected result. This three-stage workflow keeps each tool focused on a distinct job—and makes it easier to review what changed.
What each stage does
The workflow moves from changing the canvas, to combining visual inputs, to refining a chosen concept. The suggested sequence—an image extender, an image blender, and Nano Banana AI—comes from a TechBullion article published September 26, 2026; it is one proposed workflow, not a tested or exclusive tool combination (TechBullion).
1. Outpaint when the image needs more room
Outpainting generates content beyond an image’s existing boundaries. It can adapt a composition to a different aspect ratio or create space for a layout element. The extension is generated content, not part of the original capture. Check the join where the old edge meets the new area, looking for mismatches in lighting, perspective, texture, reflections, and nearby objects.
Outpainting is different from inpainting: inpainting changes selected, masked areas within an image, while outpainting extends beyond its border. Runware’s documentation distinguishes these concepts (Runware image inpainting documentation).
2. Fuse references when the result should draw from several images
Image fusion uses multiple visual inputs to guide a resulting composition. Before combining them, assign each reference a clear role: for example, one image supplies the main subject, another the environment, and a third the mood. Begin with references whose lighting and perspective can plausibly coexist; conflicting visual cues can make the composite feel incoherent.
Fusion is not implemented identically by every model or editor. The 2024 Kandinsky 3 technical paper describes that particular system as supporting image fusion and text-image fusion, among other tasks; it does not establish that all tools accept or combine references in the same way (Kandinsky 3 paper, EMNLP 2024).
3. Refine the chosen concept with a narrow instruction
Once you have selected a composition, make one important change at a time with a specific text instruction. For instance, request a change to the background lighting rather than asking for a new background, pose, clothing, and color palette together. Comparing each result with the previous version helps reveal whether the requested change also altered something you meant to keep.
How to review each handoff
Errors introduced early can remain in later versions, so review the image after every stage rather than waiting until the end. Keep the original and intermediate exports separate, and record prompts when practical. If an edit weakens the result, return to the last version you trust.

- After outpainting: inspect the old-to-new boundary, perspective, light direction, surface texture, and reflections.
- After fusion: check whether the subject, environment, and mood references have been combined coherently, and whether important details from any reference have changed.
- After text-directed edits: compare at full size and inspect identity, text, hands, logos, product details, and lighting relationships.
These checks are practical workflow recommendations, not results from a comparative tool test. The source article makes no claim of hands-on testing or measured performance.
Choose tools by capability, not by the sequence alone
The three-tool sequence is useful as a way to separate decisions, but the names of the tools do not establish that every editor supports the required features. Before adopting a particular combination, confirm that it can extend a canvas, accept multiple image references where needed, and perform the kind of language-directed edit you want. Also check how much control it gives you over references or masks, and whether you can keep and review intermediate versions. The available documentation does not support a current, comprehensive product comparison or a quality ranking.

An outpainted extension is synthetic content, and a fused composition combines visual inputs into a new image. Do not present either as an untouched photograph or as documentary evidence of something that was not captured. Preserve originals and intermediate versions so the changes can be reviewed and, when needed, reversed.
As TechBullion author Abdul Basit, writing under the byline “Beyond Boundaries,” puts it: “The tools contribute different capabilities; the creator remains responsible for the visual brief and the final truthfulness of the image.”
