Input and output
The search for krea 2 image to-image points to a specific goal: begin with an existing picture and make a changed version of it. The source supplies visual context; your instructions identify what should stay and what should change. This guide helps you plan an image-to-image request and judge the result without assuming a particular control or setting is available.
An image-to-image request is easier to evaluate when the source and intended change are considered together. A different-looking picture is not necessarily a successful edit.

Changed concept
These visuals illustrate the comparison method; they are not a verified before-and-after run from one source image. For your own image, compare the subject, framing and requested change side by side.
Start with a source you have permission to use. Write down one feature to preserve and one change to request, then check the resulting image against both. The related workflows below serve different needs.
A catalog shot needs a different backdrop while the product silhouette remains recognizable.
Use the original shot as a reference, describe the new setting, and inspect edges and labels before using any result. The krea 2 i2i guide explains the shorter name often used for this input-to-output task.
krea 2 i2iA sketch establishes a composition, but the material and lighting need another pass.
Identify the shapes that must survive the image-to-image change. The krea 2 i2i page covers how to compare a source with its proposed variation.
krea 2 i2iA reference image must move through a separately configured visual pipeline.
Document the intended input and output before choosing nodes or settings. The krea 2 comfyui workflow page focuses on planning that separate integration path, rather than treating a browser edit as an importable graph.
krea 2 comfyui workflowThis table compares two task definitions, not confirmed Krea 2 controls. Use it to decide whether your brief requires a source picture or can begin with words alone.
Image-to-image task
Text-to-image task
Image-to-image task
An existing image plus a description of the change.
Text-to-image task
A written description without a required source image.
Image-to-image task
Features identified for preservation, such as subject or framing.
Text-to-image task
Features specified in words; no source picture establishes them.
Image-to-image task
State separately what to keep and what to alter.
Text-to-image task
Describe the entire intended scene.
Image-to-image task
Compare the result with the source and the requested changes.
Text-to-image task
Compare the result with the written brief.
Image-to-image task
The requested change appears, but an important source detail drifts.
Text-to-image task
The scene looks plausible, but differs from the intended composition.
Image-to-image task
Clarify the preserved detail or narrow the requested change.
Text-to-image task
Add missing subject, composition or lighting details to the brief.
The query describes an image-to-image goal: using a picture as the starting point for a changed picture. It does not, by itself, confirm which Krea 2 controls or source-image options are currently available. Check the tool you open before preparing a detailed workflow.
Name the parts of the source that should remain recognizable, then describe the desired change. For example, preserve the camera angle and object shape while requesting different lighting. A focused request makes the result easier to assess.
Compare the source and result at the same viewing size. Check the specific details you asked to preserve, not just whether the new picture looks appealing. Look closely at text, faces and small object edges when those details matter.
Do not assume it will. Changes to style, material or lighting may also affect details you intended to keep. Review each result against your source and revise the instruction if an essential feature has shifted.
