How long is (a piece of) string? user defined tag

[dpawson]

tag added in config file

  0xd000 => {
            Name => 'SearchTag',
            Writable => 'string',
            WriteGroup => 'IFD0',
        },

Is there a limit on the length of the string value for this tag please?
If so, what is the limit please?

[Phil Harvey]

The limit for a TIFF-based file would be close to 2³².  For a JPEG file it would be 2¹⁶.

Thanks Phil.
(being awkward) - for a raw file, can I assume >256 bytes please?
That should be sufficient for my needs (cataloging)

[StarGeek]

Most RAW files are Tiff based, so I would assume the first answer.

[dpawson]

Thanks for that.
