Light relays and switches
Taken on a recent trip to some abandoned Boston & Maine railcars near North Station in Boston, MA.
I wanted some DOF play and to show the front of one of the conductor's cages.
Technical info: 6 exposures from 1/2 of a second to 1/60th of a second @ f2.8, ISO 100. Merged and processed with Nik HDR Efex Pro through Photoshop after color and lens corrections in Lightroom 3.
