On February 25, 2012, I exposed this 30-second exposure at New England Central’s yard in Palmer, Massachusetts.
I mounted my Lumix LX7 on heavy tripod, and actuated the shutter using the self-timer to minimize vibration. Note the effect of the clouds moving.
Despite the long exposure, the resulting digital image was still too dark and required work in post-processing using Lightroom.
In addition to lightening shadow areas, I also lightened the entire exposure by about full-stop, while controlling highlights and softening overall contrast.
