Feature Idea: Tag Coverage Statistics

As I read, ExifTool is tested with sample images of about 3000 camera models.

It would be very interesting to publish the exiftool reports of these models on the website. This allows exiftool users to know about the tag coverage of each model and trouble-shot model specific issues (i.e. no Exif ISO value).

Also some sort of accumulated statistic would be great (how many % of the cameras store serial numbers in the metadata etc).

The reports could be re-generated with every new exiftool production version with some sort of automated changelog (new tag discoveries, new models).

I agree this would be interesting, but a lot of work.  To digest
all this information down into a reference that is readable and
useful.  A good makernote summary is available
http://www.gvsoft.homedns.org/exif/" target="_blank">here,
but for most people this is information overload.

If you are really interested, you can download all of the files in
the https://exiftool.org/sample_images.html" target="_blank">exiftool
meta information repository and extract whatever
statistics you want yourself.

Hi Phil,

wow, this is great! Can't wait to play around with the sample data. BTW: which exiftool parameters do you use to get rid of the main photo/large preview images?

I used another utility that I wrote to do a straight swap of
the JPEG image segments.  ExifTool doesn't have an option
to do exactly this.
