Re: Filtering results like Flickr
I already replied to your email:

Interesting, thanks for the link. I didn't know that Flickr displayed makernote information. From looking at this, it is clear to me that Flickr used ExifTool as a source when developing their software because many of the tag names they use are ones that I created for information I decoded myself. But they have made a number of omissions in the value conversions, and haven't applied proper scaling to convert the values into usable units.

So yes, exiftool can display all this information in the same order, but the values won't all be the same because exiftool converts them properly.

-------

In your forum post you also ask how flickr is getting and splitting data from the photos. They have apparently been selective about the information they extract, because there is a lot of information that they are not decoding. So I would assume that they have written code similar to exiftool for parsing the makernote structure in the images, but haven't included tags that they feel are not very useful.
