Playing with Light

Philippe: So we're out playing with sunsets, as displayed below. Both my daughter and I want to catch the sunset, and the cloud flash that happens immediately afterwards. We get the sunset, and wait... About ten minutes later, we conclude the after-light fizzled, so we pack up and start to head back to the van. Not 2 minutes from the van, the clouds turn a brilliant purple, just magestic lighting... I'm *SO* going back again :P
