I just got my light stands and wanted to try them out. Found an empty business park and setup the crap. Right after I setup some shady cars showed up so we didnt stay long The car was parked at an awkward angle. Not enough light in the front. There was yellow ambient light which I managed to get rid of mostly 420ex on left 550ex on right 1/30 @ f/5.6 If I exposed longer you would see more yellow.
