I was recently hired to shoot the Trans Pacific Center at 1000 Broadway. Of course it had to be done on a very busy intersection and during the winter. In the northern hemisphere the sun is about 23° further south than in the summer and unless you have a south facing building, at least half will be in shadow. In addition, this was a block size building and the sun rose right above it. I solved this problem by shooting an additional sky and striping it in.
After blending the two images with a coupe of others and after a little more work on perspective and lighting, I arrived at the final image. Customers today won’t accept an average shot which requires Photoshop work to make it acceptable.
