Matthew James SivakandClaude Opus 5.5 7f97bdbb5f LR-IMP-PREVIEW-READ: thumbnails of Lightroom HDR/panorama DNGs develop from the file's reduced raw copies ...

A DNG that keeps reduced-resolution copies of its LinearRaw image (Lightroom merges keep 256, 512 and
2048 px ones) now develops a thumbnail or preview from the smallest copy that covers it, with the main
image's levels and colour and its crop scaled. A 23836 x 7078 drone panorama's 512 px render went from
38 s to 1.1 s. Copies are skipped when the main image has opcode lists, a linearization table or
black-level deltas, and for denoised photos.
