IDL TIFF file
Each of these images represents a single frame, all taken with the same camera settings. A is straight out of camera, from the front yard of our house back in VA. B is the same shot, after processing. C is a straight out of camera shot overlooking the Assateague lighthouse in Chincoteague National Wildlife Refuge. D is C, after processing. Note that even after processing, the background sky in B is brighter than the unprocessed sky in C. Light Pollution sucks.
