For this image I needed a day with a slight overcast so there would not be any hard shadows on the building. Using the X-Pro2 with the 100-400mm zoom and took seven horizontal images moving the camera for each exposure from the bottom of the building to the top of the spire. I also intentionally moved the camera from side to side to create a zigzag pattern when the images were stitched together later in PTGui.
Although it looks monochromatic, this image is actually in full color, but with the color saturation and vibrance dialed down in Photoshop. I straightened the vertical lines in Photoshop for more of a view camera look. To achieve the whiteness I put added a layer on top of the image in Photoshop, filled the layer with white and changed the layer mode to Soft Light. That wasn't enough so I did it again, but this time I dialed down the opacity until it looked just right.
By combining seven images from X-Pro2 I ended up with a very high resolution image and an image size large enough to make a native print 50" tall.
