This is an HDR Panoramic shot of Pittsburgh from the top of Mt. Washington. I was up there Saturday night and I took 5 bracketed shots for a total of 15 images. I then made 3 different panoramic images of the city using photomerge in photoshop. I then put all three images in the same file as different layers and realigned them. Then, I saved them out and created a high dynamic range image using photomatix. I used their tonemapping feature and saved it out as a 16 bit tiff. I brought it back into lightroom and made a few adjustments in lightroom and photoshop before saving it out for web.
