Shrink and Shrink to a Quality Target now keep an iPhone photograph's HDR gain map when they replace the file. Until now they dropped it and said so: the photograph still opened and looked right on an ordinary display, but it looked flat on the display it was taken for. macOS will only decode a gain map beside a picture its own encoder wrote, so for a photograph that has one, the system encoder writes the file and the map is copied across from the original. That costs about 30% more bytes than Squint's usual encoder at the same score, and it is used only when there is a map to keep. Measured on an iPhone 12 portrait: 3,995 KB to 1,505 KB with Shrink, the HDR headroom 4.00 before and after, and no location, camera or date left in the file.
Shrink for Email and Shrink for Social still drop the map. They make a smaller copy to send, and the original beside them keeps its range.
The window's picker now offers all six treatments the Finder entries do: Shrink, Email, Social, Quality, AVIF and Strip. A photo can be dropped on the window and sent through any of them, which matters in folders where Finder shows no Services entries.
