Getting this right was really hard! I'm gonna say tubes are the most challenging light painting technique I've tried yet. On this evening we had windy conditions and also a dramatic sunset which added to the difficulty of getting the exposure right. There were some really bright and really dark areas of sky, rather than a more uniform blue hour. There was no way around doing a compisite to get the foreground visible in this situation. Advice or feedback from other tube tribers would be most welcome! Had some great collaborators for the evening, an all-female crew. Thanks @p.agerage, Yamilla and Alix!
