Even though you need the name for an entry in the digital database,
presumably the "Joe E. Blow" is based on an entry in a finding aid, a
card in a special collections file, a biographical dictionary, a
caption on a photograph, or something along those lines. I'd use that
as the basis for my 670 on my authority record, not the data in Early
Seattle photographs.

I would say this is a circumstance where "Work cat." is not necessary.
It's all reference works and the database you're building is a
candidate to become a new biographical resource that will used by
others. If you decide you need a 670 from your new image database, and
if "Early Seattle photographs" is the title of the resource, I think
all you need is:

670  Early Seattle photographs, [date of search, or viewed on date] $b
