In the middle of the dance, I had realized I had not taken a good ring photo for the couple. The wedding ceremony table that had been set up by the party hall was left throughout the duration of the dance, which I took advantage of, especially the blue LED lighting that was part of the hall and the candle that was still lit.

Blue color is from the LED lighting that lit the ceremonial table. The rings were then desaturated to black/white then sharpened more than the rest of the image, that was basically kept natural.
