I should have been more clear with what I want to do. I don't actually need to change settings or have a live preview of the cameras on my computer.
this is an open issue, we have only
viewtopic.php?f=20&t=2520 for now,
you could also make experiments with ptpcamgui and chdkptp (see in the chdk forums for an description how)
live preview sound fine and changing settings also, but for now we have only proof of concepts, ideas and first alphas
in the mean time you could probably scan all your books, with the classic method ((LCD screen or video capture stick) connected to video out of the cameras and changing setting at the beginning by hand)

if your camera is in the list you will probably be able to do this, but changing settings is more complicated (some camera have SDK or special software for this, but the they have problems with more that one camera, a long way to go)
booknut wrote: Will I need to use chdk as well?
no, and yes chdk is for canon cameras and is a other way to change settings, trigger, download, and ... this cameras, but is an hack and it has to be done for every camera model, the live view is still in development, IMHO the chance that the a3300is will get live view are 70% (it is just a question if someone will make the modification on the firmware)

chdk and gphoto are different play fields
my suggestion is, bye a3300 scan the classic way and wait, maybe one or two years
