fotoShare is an iOS app that runs on your iPad. It downloads images created by dslrBooth on your windows or mac and allows your guests to navigate through the images and share the images. This frees up your booth and allows your guests more access to your images.
fotoShare downloads images directly from dslrBooth if both are on the same network. If not on the same network, fotoShare will download your prints from dslrBooth's servers provided you have Enhanced Sharing turned on in dslrBooth.
