Howdy Heinz. A colour photo?? Must be the 2M's or Laurantina's from the bar, two stone throws from this that clouded your judgement as you usually shoot B&W
Seriously though, stunning light often happens when one is the least prepared . You can sit/ stand, tripod set up with a perfect composition day in and day out, weeks on end and on the one day you decide enough is enough, you are just going to have a quiet beer with the sunset and then, lo and behold, nature puts on a show. Stuff happens.
Thanks for sharing Heinz.
