Well went into Chicago yesterday afternoon for that cityscape photo shoot. The problem with shooting Chicago city from the East is that you have the sun setting behind the buildings leaving them in shadows. So the only real time to shoot here was after the sun was most the way down. I did have a look at one with great cloud cover but the buildings are just shadows.
This is the same photo with a different crop. Each exposure for this stitch was at 50 secs at f11. I knew what would be possible on this shot as it was an overcast day with some flat clouds rolling through. When you have such bright city lights and such a long shutter speed you pick up all the light on the clouds that are being lit up by the city. Usually you can see a red tinge in the clouds but the camera sees it like this. This red is also picked up by the buildings and can blow out the lighter coloured buildings.
The reds were brought back in PS to get a nicer golden hue, the blacks were enhanced in the buildings and a vignette was added to the 3:1 image.
There was a bunch of Asian tourists gathered around watching my monitor as I released the shutter and the image showed up.
I am not sure which crop I prefer. Although the 4:1 ratio has a very dark area I feel it helps composition and intensifies the buildings (that are pretty damn bright already anyway).
Not jaw dropping photos but interesting none the less…
