Digital image post processing: Question on adding data to a photo

[Anomalocaris]

I’ve got a young lady in Atlanta doing an inventory of the National Park Service’s Martin Luther King Collection. One of the requirements is photography of about 1200 items in the collection that the Park Service doesn’t currently have good digital photographs of. I’m hoping someone here can point me in the right direction of a method of adding data to a JPG file. We will be capturing the images as RAW (NEF since the camera is a NIKON D750) and JPG. The customer’s requirement is Tiff and JPG. We need to batch convert the RAW files to Tiff. That part is easy enough, but we also need to add the object’s accession number and a date to the JPG. The end result needs to look like this.



I need to add the black rectangle with the object name and data. Are there any tools available that would let us add the data we need to the digital file’s metadata then extract it out and put it in the JPG in a batch process. Can we do it in real time with a laptop connected to the camera? Are we stuck with doing that manually one photo at a time in Photoshop or something?
