EXIF Extraction library.
EXIF stands for Exchangeable Image File Format, the format used to store interchange information in photo files, particularly JPEGs though it is also used in TIFFs. Most digital cameras now include EXIF information.
I've put the first (let's call it alpha :-) version of my EXIF extraction library up on RevOnline. (category Programming, or under my username alextweedly).
The stack is intended to be used as a library, but it includes a "Test" button to try it out on your own photo files, and an "Info & help" button which will (some day) give real documentation. See the script under "Test" button for the essentials.
It can extract much of the EXIF information included in JPEG and TIFF files. I don't yet decode manufacturer specific "Makernote" info - I have the necessary information for a few manufacturers ready to code - but don't yet have it for Pentax *ist D (i.e. my own camera !!), so that's not top of the priority list.
I've tested it on a few hundred photos, from probably 20 different cameras - so I'm sure there are more crufty variations that it hasn't yet been tested against. I'd be grateful for any reports of misbehaviour or problems.
Now that I actually have something I think is worth sharing, I'll go start on my RunRev web page.
Thanks -- Alex.
