Another method for capturing an image where you need to deal with the shear size of large structures is the method of stitching.  Simply this is taking several photos of a large scene and then using software to overlay or stich them together.  The example used here is of York cathedral.  Below are the photos that were stitched together to make the final image.  The best way to create images for stitching, is to use a tripod fitted with a panoramic attachment and carefully cover the area with multiple exposures, but you can get very acceptable results hand holding covering the area.  Again the first step is to do standard lens and colour correction with in your raw converter (such as Camera Raw) all images needed to be treated the same although custom exposure and shadow correction can improve the final image.  Again my main tool is the merge tool in CS6, but similar tools are available.  Usually the spherical or cylindrical algorithms work best.  After the stitched image is produced (see below), can then use the transform tools can be used to remove any distortion that needs additional correction.

York Cathedral

York Minster is one of the largest of its kind in Northern Europe. The minster has a very wide Decorated Gothic nave and chapter house, a Perpendicular Gothic choir and east end and Early English north and south transepts. The nave contains the West Window, constructed in 1338, and over the Lady Chapel in the east end is the Great East Window, (finished in 1408), the largest expanse of medieval stained glass in the world. In the north transept is the Five Sisters Window, each lancet being over 16 metres (52 ft) high. The south transept contains a famous rose window, while the West Window contains a famous heart-shaped design, colloquially known as 'The Heart of Yorkshire'.
