It was my first attempt using a B&W Variable Neutral Density Filter (0.3-1.5 - Reduce Exposure by 1-5 Stops). I shot this, this morning between 11:00 AM & 12:00PM). Total 9 shots at 0.4 sec each at different increments on the aforementioned filter from lightest to darkest. Converted to HDR in LR - Processed & then B&W conversion in Silver Efex Pro 2.
