I'm fiddling with a new pinhole cap lens. The obsessive-compulsive part of me wants to batch fix the EXIF data to show "Pinhole" under the lens information, and add in the correct approximate aperture and extension tube info too. I have or have access to the usual Canon software, Photoshop/Bridge, and a couple other tools.
Does anyone have a quick batch workflow for patching EXIF data in multiple files? As far as I know the fields I want to modify exist automatically from the camera (though most viewing/editing software will ignore fields with blank data by default).
Of course, if someone is knowledgeable about adding an identifier chip to the pinhole cap, that could be a fun project, though I don't know if those can be programmed to take into account the use of extension tubes.
