Hello,
I have been dealing with multi camera rig for couple of years and found it’s not so easy to download photos from a big number of cameras reliably even with a professional software. Last year I built a rig with 128 sets of Canon T3i downloading photos with this method. It has been proved to be not only reliable but also very easy to operate. The method is base on Windows Explorer in Windows 7 OP. Should anybody be interested in it, I am glad to share with you.
