Canon 6D
Rokinon 14mm F2.8 lens @ F2.8
ISO 1600, 20 second exposure.
I changed the color temperature in Adobe RAW from 3700 to 3000 to give it a 'colder' look. I used Nik Effects Viveza filters in Photoshop to kick up the contrast, sharpness and saturation. I used Nik effects dfine filter to control noise on the structure. However, I did not use it on the background sky.
