do you really think an exif field is a good place for that? I am not too sure about whether one can simply add further fields to exif and even if one could, what software (besides subsurface itself) would be able to read that data. One could use the z coordinate of the geolocation field but that would be misuse and still not really parseble.

Besides that, the exif library we currently use is read only, we would need to use a different one.

I could think of other ways to export the depth information of images: Spit out a html file with links to the images and the depth in captions (i.e. human readable), add the depth to the filename, write out a text file with file names and depth info.

What do you think? Could you ask your biologist friend what kind of data format would be most useful?

Best
Robert
