Edit AI images without losing the parts you like
Use a change list, preserve list, and simple review sheet to direct image revisions.
An image edit needs two instructions: what changes and what stays.
Write a preserve list
Once an image has a composition you like, record the important constants: the subject’s position, clothing, object shape, palette, and crop. Then write the change separately. “Make the background lighter” is easier to assess when the subject and framing are explicitly stable. The tool may still change them, which is why the preserve list also becomes your review checklist.
Use an actual reference for continuity
If continuity matters across a set, work from the same approved reference rather than relying only on a repeated description. Name distinctive details such as a chipped handle or a striped sleeve. Do not assume that reusing a prompt will recreate the same character or object. Compare each output with the reference before you approve it for the set.
Separate exploration from production
During exploration, broad alternatives are useful: illustration versus photography, warm versus cool, close versus wide. During production, you need consistency. Freeze the approved direction in a short brief and number the versions. Save the original before editing. Keep a note such as “version 3: background fixed, label still wrong” so you do not lose track of what remains.
Check what the revision accidentally changed
Compare the whole image, not just the requested area. An edit to a window may alter a reflection, a face, or nearby text. View the output at full size and at its final display size. If you cannot get a small precise detail right through generation, finish that detail in an appropriate editing tool instead of letting repeated revisions damage the rest of the image.
A worked example
Original teaching example, not a recorded model run.
Vague starting point: Make it better, but keep it the same.
A more useful brief
Keep the mug’s shape, blue glaze, position, and camera angle. Change only the background to a pale gray wall. Preserve the handle opening and the shadow direction. Do not add lettering or extra objects.
Why this helps: A concrete preserve list turns a vague preference into a comparison you can perform.
Your turn
Take an image you are allowed to edit. Write three things to preserve and one thing to change. Compare the result against all four.
You are looking for this: The requested change is present and you have checked the preserved details, not just the new background.
A quick check
After an edit, what should you inspect?
- Only the part you asked to change
- The whole image, including the parts meant to stay fixed
- Only the thumbnail
Answer: The whole image, including the parts meant to stay fixed
Unrequested changes can appear outside the edited area.
