Install

Unzip, and move Cut Corners.lrplugin somewhere permanent.
In Lightroom Classic: File → Plug-in Manager → Add, select the plugin folder.
Select some scans and run Library → Plug-in Extras → Cut Corners: Auto-crop film frames.

Something not working? Plug-in Manager → Cut Corners: Support → Run Diagnostics pinpoints the problem, or see the support page.

Licensing

The trial covers your first 30 cropped images — most of a roll, with every feature enabled (dry runs never count against it). After that, a one-time $19 license key keeps it cropping forever. Enter the key in the run dialog or in Plug-in Manager → Cut Corners: License.
