The Mountain in Motion
I tried forever to get this shot. I finally managed to get the color and composition just the way I wanted it.
To get this shot, I had to make use of HDR, otherwise I could not expose for both the mountain and the sky. I captured 5 exposures (+/- 1, 2) with no train to form the base of the image. Then, I took a 6th shot as a long exposure in order to capture the motion blur of the train.
I merged the first 5 exposures in Photomatix to create my HDR. Then, I took the 16-bit TIFF generated by Photomatix, along with the 6th exposure and edited them in Photoshop CS3. I used the HDR image as the top layer, with the train exposure as the bottom layer. I reduced the opacity on the top layer to about 30% so I could see the train underneath, and began to erase over the train on the top layer. This allowed me to combine both images into a seamless one.
From there, I merged the layers and saved the edited image. I reimported it back into Aperture and adjusted the colors and contrast slightly, reduced noise, and straightened the image.
