the photo is from 4 shots hand held (2 shots in 2 rows) stitched with Microsoft ICE stitcher program (free for Windows) and PP with LR 3<br />
<br />
an ideal solution with static objects, when you need more wide angle, than you have on the camera or more resolution.<br />

M9 set to manual exposure! don't forget to fix the ISO, I forgot on this one and on close inspection you see some boundaries between the shots.
