Currently Dropbox allows you to choose the nomenclature convention of the items inside a folder:
Organize -> Set Naming Convention -> Establish Nomenclature Convention
This is great...
BUT, there is NO option that creates the SAME nomenclature as the one that Dropbox uses for the Camera Uploads: "YYYY-MM-DD HH.MM.SS". A format I LOVE.
Currently the closest option Dropbox gives you is: "YYYY-MM-DD-HH.MM" but that's not the same.
Dropbox, please add the option of "YYYY-MM-DD HH.MM.SS" to your nomenclature conventions so we can easily match images to those imported in Camera Uploads.
