photo: GRD4 Scene Mode: Train Trails

I shot this image in the Star Trails mode from the Scene selection on my GRD4 using 15 second exposures. The subject is a rural highway and pair of railroad tracks taken from atop an adjacent mountain in the Arizona desert. This is a JPG, which is the only output this form of shooting will provide, to my dismay. I'm not real happy with the quality and so I'm going to try and see if I can accomplish a simiilar effect using the Interval mode and then stacking in Photoshop using the appropriate blending mode.  I cropped a bit and did some post processing in Lightroom 4.2

Railroad tracks between Gila Bend and Maricopa, running through the Maricopa Mountains.

All comments and criticisms always welcomed.
