Taken with my Samsung NX1 and SMC Pentax 28mm f/2.8. I am guessing about the lens, EXIF data is of no help. Could have been my SMC Pentax M 20mm f/4 but I doubt it. The perspective and field of view seems kinda normal. Either way, the SMC kept flare under control.
As the thread title states, this is a stupid trick that just kinda happened. My game plan was manual mode, taking a few shots to get the exposure right for the low sun. Apart from that, I can't tell you what the actual trick is. Must be down to the way the Samsung sensor handles vastly blown out highlights.
