Here are a couple of photos from a recent commission for GIHLondon.
Tall buildings, such as those presented here, can be rather tricky to capture. London streets are often tight and awkward, and even with a 24mm tilt-shift lens it can be a struggle fitting everything in.
Both of these buildings required two shots - one levelled off, the second tilted up. I then manually stitched the photos together in Photoshop. Small tilts can be corrected with PTLens - you simply dial in the angle and the software does the rest. The finished result appears as though it was taken with a remarkably wide tilt-shift lens, or a large format camera.
