Eastbound BNSF train crossing National Trails High way (Historic Route 66) just east of Ludlow, CA [March 2009]
I took two images, the first one of the gates dropping when the train activated them (15 seconds @ f/4, ISO 200) and the second one when the train first crossed through the gates (15 seconds @ f/4, ISO 200). I had no intentions of combining the images at the time. This was an experiment with the HDR merge .
I generally do not care for HDR pictures, but I DO LIKE your combined photos done with HDR merge!
