I did a dual conversion from RAW just to see what I could pull out of the sensor
this seen is only illuminated by the moonlight
the spots in the dark bits likely are due to sensor strain, though note the near equally dark brick doesn't show them ...I think these shingles have some iridescence in their composition, perhaps from silica, though I think some come from the sensor really being pushed to its limit ...amazing that the sensor held this much detail
I see a great deal more detail in this photo than I could remember seeing with my eyes that night
a jpg version follows, which was an even greater revealation for me
