Initial problem
Anamorphic still photography often leaves photographers with folders of squeezed RAW or rendered files that need consistent desqueeze handling before editing. The original RAW files should stay untouched, but manual export workflows are slow, repetitive, and easy to misconfigure across large batches.
Implementation
PhotoDesqueeze is a native macOS SwiftUI app that scans an input folder, previews images side by side, applies the selected anamorphic factor, and writes 16-bit TIFF masters for editing. It uses Apple Core Image for RAW-first loading, supports rendered fallback formats, offers preflight counts, cancellation, retry-failed processing, automatic or manual axis selection, color-space choices, safe existing-file handling, and a CSV manifest for each batch.

Impact
What mattered
Batch anamorphic desqueeze for RAW and rendered image folders
Original RAW files stay untouched while 16-bit TIFF masters are written
Built-in 1.33x, 1.55x, 1.60x, 1.80x, and 2.00x presets plus custom factors
Preflight summary with planned write, rename, overwrite, and skip counts
Side-by-side preview, progress, cancellation, retry-failed, and per-file results
CSV manifest, atomic TIFF writes, and conservative TIFF/EXIF metadata preservation
