The idea behind the shot was to get the wide angle perspective of the Simmons Hall, with trail of clouds in the background. The vertical facade, because of the camera position and perspective, gives the illusion of a horizontal surface. To get the type of cloud trails displayed here, the sky needs a variety of scattered moving clouds. The camera needs to be set for a long exposure, typically minutes, depending on the desired length of trails and current speed of clouds.
For this photo, the camera was put on remote bulb mode to expose for 95 seconds. The aperture was set to f/9 so that the depth of field is wide and also to reduce the amount of light coming into the camera over the long exposure. The focus was set to hyper-focal length corresponding to f/9, to obtained reasonable overall sharpness. Because the facades are not uniformly illuminated, a hand held flash gun was fired to fill light in darker areas. A sturdy tripod was used to avoid blurring due to wind.
The editing steps involved correcting for exposure by editing the curves. The saturation was boosted to bring out the details in the colored windows. The image was edited in Photoshop to remove branches of the trees on the top side of the image.
Aperture:
ƒ/9.0
Exposure Time:
95.0 sec.
Sensitivity:
ISO 200
Effective Focal Length:
21 mm
