Why Lens Correction Can Trim the Edge of a Photo Copy
By ImgHeal · Updated
Lens and geometry corrections can change the frame boundary, and an automatic constrained crop may hide pixels near the edges. Compare the complete camera source with the developed export before concluding that the original capture omitted a corner. Keep a full reference and save a separate corrected derivative with its framing choices documented.

Find the first cropped version
Compare the camera original, RAW preview, developed image, and final export. Identify whether the edge disappears after a lens profile, perspective adjustment, or a crop setting. Adobe's Camera Raw workflow includes lens and geometry corrections with constrained cropping. Those operations can be useful for capture defects, but they should not silently define the only retained source framing. Record any automatic defaults that affected the copied print's complete border.
Review corrected geometry separately from crop
On a duplicate development, compare the correction with and without its associated crop where the software permits. Inspect remaining boundaries and empty areas created by the transform. A rectangular filled frame is not always the best source record if it removes inscriptions or hands. Do not disable a necessary correction solely to preserve a neat outer rectangle; keep an additional full-frame source and choose the viewing crop deliberately after understanding both effects.
Save complete evidence and a usable derivative
Retain the camera file and a developed reference that explains the full captured area, then export the intended restoration input separately. Check its dimensions, orientation, faces, and all four edges. Record any geometry change and avoid generated border expansion unless it serves an explicitly labeled creative purpose. A corrected image may be easier to view while still differing from the original object's shape or losing some boundary content through resampling and crop.

Questions about this restoration task
Does an empty wedge after correction mean the camera missed the print?
Not necessarily. Geometry correction can move the captured image within a new frame. Compare the retained camera source before deciding whether a recapture is needed.
