A stitch, in time.

Brisbane seen from South Bank

When your wide isn't wide enough, Photoshop can come to the rescue in post. I'm always impressed by the program's ability to seamlessly stitch images together while correcting for the vignetting and the geometric distortion.

The image above comes out of three 19mm frames. Because this allowed me to discard the extreme edges, the final image holds plenty of detail (not visible in this low-res rendition), even at the edges.

Story Bridge in Brisbane

The bridge picture, above, came out of 14 images stitched together. Because the resulting image was so large, the downsampling fixed up the problems arising from it being hand held, and the noise.

Interestingly, to make the same image of the bridge with a single lens, would require a 14mm at f/0.76. The depth of field is impossibly narrow for a single lens, but that can't be seen with a subject at this distance. 

The same effect can be applied to a much closer subject. The tactic to create a wide image with impossibly short depth of field by stitching multiple images together has come to be called the Brenizer Method.
