The main camera was photographic, Hasselblad. The mag tapes were prepared from Hasselblad negatives. many of the interesting Hasselblad images were published all over, including Life magazine and prints were distributed at every trade show. Collections of prints were published in bound form, some of which may still be available from the US Gov't Printing Office or found in public libraries.
Hoagland is concerned with the loss of the mag tapes because they may show objects on the horizon that shouldn't be there.
I'd just like to recommend the DVD 'For All Mankind' for it's excellent quality video of the Appolo missions.
In one shot you can see the wires being used to fake up 1/6 gravity /sarc.
