It seems I keep forgetting this, so here it goes: after class, I sync pictures from my phone and camera, and then try to merge the two so I get one set of images to produce a PDF from. The camera has one naming standard, and the phone … the same. So there’s a potential for conflicts. I do know, however, that I’m not using the phone and the camera at the same time. So renaming the files, using their EXIF timestamp, should be safe. This is how to do that:
jhead -n%Y%m%d-%H%M%S *
Then just merge the two folders into one.
