title: Connect to digital camera from cellphone?
body: <p>A customer (photographer) asked me, if it was possible to write some kind of software for cellphones, so he could physically connect it to his professional digital camera (Canon or Nikon) and transfer the pictures (or a subset) to the cellphone.</p>
  
  <p>I am trying not to put constraints on cellphone platform (Symbian, Windows Mobile etc) from the beginning, so I am leaving that sort of constraints out on purpose.</p>
  
  <p>Can anybody give me some hints?</p>
