Where is the tiff compression/encoding metadata field?

[ChrisM]

Hi

I can't seem to find the tiff compression metadata field. In Media pro, it is called "encoding" and let's you know whether the tiff was compressed as a LZW or what have you. Does this exist in Photo supreme? I looked under advanced- and compression only tells me the number- not the type.

Thanks

I found that as well- but it does not inform on the encoding of the compression- just the number.... At least in my example.

Values and compression types references:

https://exiftool.org/TagNames/EXIF.html#Compression

https://en.wikipedia.org/wiki/TIFF#TIFF_Compression_Tag

Deflate is ZIP.

I am still using Version 6 and this appears to work:

- On the Info panel you can create custom fields.
- Click on New Custom Field.
- Add Macro Field.
- Enter a name for the On-Screen Caption.
- Delete the %FileName entry.
- Click on the + button: Add Metadata Item - Exif (if available) - Exif Information - Compression.

This field displays the compression type. Based on my limited testing: For a "1", "Uncompressed", the field displays "TIFF".

You can add the compression tag as a custom thumb line, or add it as a "predefined" custom field in the Info Panel.

The custom thumb line is %xmp:tiff:Compression{encode=html}
You can of course also select the COmpression tag from the drop down:
Advanced -> XMP -> XMP Properties -> TIFF Properties -> Compression.

Am I being dense? I want it to say LZW for example....

Works here OK ? I saved a file with each of the compression methods and added the field to the bottom of the thumbnail description;
