sneak	78c64061a3	README: give exif()'s formats as examples, TIFF among them ... The read surface listed JPEG, HEIC/HEIF, AVIF, PNG and WebP as every format exif() reads, but exifreader reads more, so "any other original gives {}" was false. The list is now examples. Model: opus-5-5	2026-10-01 20:23:38 +00:00
sneak	0813163e4d	Drop exifreader's faulty-value text; test unnamed EXIF tags ... A text tag whose value lies outside the file, which exifreader reads as "<faulty value>", no longer gives a make, model, lens model or offset field. Tests cover such a JPEG and the backup-metadata dump keying a tag exifreader has no name for as undefined-<tag number>. Model: opus-5-5	2026-10-01 19:59:36 +00:00
sneak	e623fd2015	Read GPSAltitude without its reference tag; keep unnamed EXIF tags ... exif() takes the altitude from the GPSAltitude tag and negates it only when GPSAltitudeRef is 1, so a file with GPSAltitude and no GPSAltitudeRef keeps its altitude, above sea level. A test covers that file. backup-metadata --exif keeps the EXIF tags exifreader has no name for. The comments in src/exif.ts say the thumbnail's tags are not kept and that a tag with several values computes to an array. Model: opus-5-5	2026-10-01 19:35:52 +00:00
sneak	9c0c7c9489	Test the unset-clock EXIF date; drop the old dump layout from README ... Add a readPhotoExif test: EXIF whose DateTimeOriginal is 0000:00:00 00:00:00, as a camera with an unset clock writes it, gives no dateTimeOriginal while its other fields are still read. Remove the README sentence describing the backup's exif field in dumps from an earlier version. Model: opus-5-5	2026-10-01 19:14:59 +00:00
sneak	a13ec66bca	exif(): read HEIF/HEIC originals with exifreader (closes #145) ... photo.exif() and backup-metadata --exif read EXIF with exifreader, which reads JPEG, HEIC/HEIF, AVIF, PNG and WebP, so a HEIC original or a live photo's HEIC image gets its EXIF. exifreader replaces exif-reader and the hand-written JPEG segment scan. PhotoExif is unchanged. The exif field of backup-metadata --exif is now exifreader's tag output, and exifRaw holds the whole EXIF block it could not read. Tests use a real 933-byte HEIC fixture, test/exif.heic, whose recipe is in test/exif-heic.ts. Model: opus-5-5	2026-10-01 18:22:00 +00:00
