Although my main focus is video I'm starting to love my 50D for photography.
I've been experimenting with photo matrixing, taking multiple shots of interesting architecture around Riga, Latvia.
Here's one of my first efforts (click link below for scaled to HD image):
This shot is made up of 15 x 15mp images (3rows/5 columns). Original composite is around 19000px wide. Shot on an old, manual Auto Revuenon 50mm F1.4 but using ML Auto ETTR. Processed with ACR and Microsoft ICE (for stitching the images)
I hadn't heard of ICE until I went looking and it's fantastic. Beats Canon's photo stitch and Photoshop photomerge. Well worth the FREE download if you're on PC http://research.microsoft.com/en-us/um/redmond/groups/ivm/ICE/

: Here is a small gallery with a few more. Shot with ML Dual ISO
(up to 70x shots per composite/up to 58k pixels wide) Images scaled to about 3-5% of their original size for web viewing http://imgbox.com/g/NMOHCoarPn
