Include a little film border to diagnose a negative scan
The rebate can anchor frame position, density and colour conversion.
A tightly cropped scan may remove the film border that helps interpret a photobooth negative. Keeping a small rebate can make later colour correction and frame mapping more reliable.
Use the border as a reference
The film margin can show edge markings and unexposed base around a frame. A negative-aware scanner may use clear or unexposed areas during conversion. Preserve enough border to identify the frame without letting the holder dominate automatic exposure.

Avoid automatic crop surprises
Thumbnail detection can split or trim a strip incorrectly, especially when frame boundaries are faint or the holder is visible. Compare the detected crop with a normal preview and adjust the frame area manually when needed.

Save two versions
Keep a master scan that includes the frame edge, then create a cropped image for sharing or printing. Link both files in the scan log. This preserves the evidence while giving the strip layout a clean portrait rectangle. Keep frame numbers where possible; they help map a crop back to the original strip during later review.
