Thanks, guys, for the kind words.
The pictures above were taken on very dark streets in Bangkok where there generally are no street lamps, so that the lighting usually comes from food stall and shop lights — most of these are white fluorescent lights but sometimes there is still some tungsten lighting and there is also a lot of colored fluorescent advertising signs, as well as some strongly colored LED lights. In the third picture the red comes from some adjacent red LED lights whose coloration of the sides of the picture I didn't want to remove when processing the picture.
Giorgio -thanks for looking at my photo essay; it's very encouraging to get a comment such as yours — though I don't mind negative critique, since that often gives one something to thinks about as well.
