Make & keep
Crop a photo strip in GIMP while keeping a clean source
Make a working copy before trimming the scan for a finished print.
A scan often needs a tighter edge for a display copy, while the full frame remains useful for records. In GIMP, duplicate the image first, then crop the duplicate. This gives the finished file a deliberate boundary without making the only working version depend on undo history.
Duplicate the image
Choose Image → Duplicate before trimming. GIMP opens a separate image window containing the image data, so the source and the crop can be inspected side by side. Give the duplicate a clear working name before changing its canvas.

Set the crop
Select the Crop tool and drag a rectangle around the strip. In Tool Options, enter a fixed width and height or lock a ratio when the output needs a repeatable shape. Move the rectangle to retain the complete printed border.

Check and commit
Inspect every edge at full zoom, especially the bottom cut and any handwritten note. Apply the crop only on the duplicate, then save it under a new filename. Reopen the original to confirm it still shows the uncropped scan.
