HDR example

HDR is closer to what your eyes can distinguish when you are looking.  You see the shadows, the clouds look puffy and white and you don’t see almost black shadows.  Your eyes see a wider spectrum of light than the camera can record.  HDR makes that possible by combining parts of multiple pictures into one.  I took two pictures one normal and one underexposed.  Not intending to use HDR.  I just tried it and this is the result.
