could you explain the process a bit more .
im not sure on which step the code replacement would run . also how it would look.
do i set the codereplacement
{filenamebase}photographerA photographerA Caption ?
You said earlier that each photographer would have custom filenames out of their camera so I'll assume they'll be in this type of format:
ABC_0001.JPG
DEF_0001.CR2
GHI_0001.NEF
etc.
(the filename extension won't matter)
Your Code Replacement file would look like this:
ABC[tab]Caption text[tab]Photographer Name[tab]etc.
DEF[tab]Caption text[tab]Photographer Name[tab]etc.
GHI[tab]Caption text[tab]Photographer Name[tab]etc.
([tab] should be where you press the Tab key on your keyboard as you're entering the text. Tab is the column delimiter in Code Replacement files.)
In your IPTC Stationery Pad you'd enter (assuming the default Code Replacement delimiter of '\', if you use something different substitute yours) :
Caption field: \{filenamebase:0,3}#1\
Photographer field: \{filenamebase:0,3}#2\
...
Then save your IPTC Stationery Pad.
During Ingest, apply the IPTC Stationery Pad and your images will have the proper values for each photographer filled in.
