Nice shots bojan, my favourite is the second one. Partly because it's nice to see someone else who suffers from the same condition as me - "horizon unstraightus".
All of those were done with Kyocera digital 1.3M That means - point & shoot.. But normally for pics like that I am using my old Practica VLC..... and then scanner on negative. This is giving me >30Mpixels (when needed )
