For those who are interested: I have done some test with Python+gphoto2 and my program can capture multiple images, change camera configs and then quickly capture new images without crashing tablet. Also you need to initialize gphoto2 only once, meaning that after short "warmup time" you can capture images almost instantly.

I planned releasing this code after it was ready, but I have been quite busy last few months so I haven't had time to develope this any further. When I have more time I might continue. If you feel adventureus you can try to do something useful with my code, but keep in mind that it has only about 10 hours of testing/coding under its belt and about 10 minutes of planning. I'm quite sure that all coding should be redone.

Also note that this is my first python program and I mainly do development for non OOP-language (Matlab) and that I don't have very good knowladge about libgphoto2, so code is quite messy

Code is not stable and will probably still crash your tablet. If you use program as root, it tries to control USB (otg<->host). This should prevent crashing (Problem seems to be related to one (possible) kernel bug, but I can't find my bookmark).

Note that by messing with camera configs you can possible brick your camera. If you try to change camera configs to something that is not supporte by camera, it might freeze (try removing battery). I have done all developing with Nikon D300 and it was capable of recovering from freezes, but don't count on that.

Program needs libgphoto2 and libgphoto2-python bindigs that you can find from
http://gphoto.svn.sourceforge.net/vi...photo2-python/
svn co https://gphoto.svn.sourceforge.net/s...gphoto2-python

If you have anything to ask (or you want to pressure me to continue developing , you can contact me by email (it's in the source).
