LumaShare is an iOS app that runs on your iPad/iPhone.
It downloads images created by LumaBooth for Windows (dslrBooth) or LumaBooth and allows your guests to view and share the photos and videos from the booth app. This frees up your booth and allows your guests more access to your images.
LumaShare downloads images directly from LumaBooth for Windows (dslrBooth) or LumaBooth if both are on the same network. If not on the same network, LumaShare will download your prints from the LumaBooth for Windows (dslrBooth) servers provided you have Enhanced Sharing turned on in LumaBooth for Windows (dslrBooth).
