I don't know if this is the correct forum but here goes.
Often on a dive trip, I try to put a slide show together from everyone's photos. If everyone has a laptop this usually isn't an issue. I bring a Mac Air and a bunch of usb sticks (some windows/some mac) and things are fine. On our last trip though, most of the other photographers had their photos on an iPad and had organized them into a favorites folder (10 photos of the 5000 or so on the iPad). How in he** can you download from a folder on the ipad to my mac. The solution needs to be WIFI free i.e. there is usually no wifi available and has to be local to either my mac or my ipad since the other ipads can't simply download the app since there is no wifi and often no cell signal either to create a local hotspot.
Any suggestions are appreciated,
