I have used different Olympus digicams, but the "Make" EXIF field is not consistent in their images. This means certain image management software groups them into different manufacturers, such as "OLYMPUS IMAGING" and "OLYMPUS OPTICAL" as well as simply "OLYMPUS."
So I want to examine a huge number of pictures' EXIF data, look for a "Make" tag that begins with "OLYMPUS ", and change all those so they simply say "OLYMPUS".
Is this possible using only exiftool? I can do some bash or perl scripting, but I was under the impression that exiftool could do this sort of thing all on its own. I don't really want to fire up exiftool 400,000 times inside some other script if I don't have to.
I did Read The Fine Manual, but the ~80 page man page for exiftool is pretty intimidating, and I didn't see this sort of functionality right off the bat.
