When I create a TIF positive file the keywords attached to the TIF file are wrong. If a keyword on the RAW file is in a hierarchy, every keyword in the hierarchy is attached to the TIF file, even though they were not attached to the RAW file. That produces a lot of extraneous keywords.
Worse is the fact that the keyword at the bottom of the hierarchy, the only one that should be attached to the TIF, is assigned to the TIF but is not part of the hierarchy. It is now an independent keyword. This creates duplicate keywords. It makes a mess of my keyword structure.
Worse yet is the fact that occasionally I get TIFs with new keywords. The new keyword I have seen is “Film Photography”. I don’t have such a keyword so I don’t know where that comes from.
The keyword management for created positive files has some problems that need attention. At this time anytime I create a positive I have to carefully review and correct the keywords. It a PITA.
