This is what I am trying to accomplish:
I am doing imaging diagnostics outdoors using a RPI 2 and a DSLR camera (to which the Pi connects and controls via gphoto2). I have a bunch of python scripts on the pi which automate the process of collecting images and process them.
Nonetheless, I would like to setup a webserver on the pi, which will also host a webpage to which I can connect from lets say an ipad and run the imaging scripts from this webpage. I will not have internet connectivity on field so I would like the pi to work as a sort of "router", so that from the ipad's wifi connections I can connect to the pi, logon to the webpage hosted on the pi and run the scripts which will return to the ipad's browser a preview image of the result of the scripts.
I know this is confusing how I explained it, but I hope it makes somewhat sense. I just need pointers on how this should be done (names of webservers I should use, etc.), not the entire process. I'll figure that out afterwards.
