Was your engine cold or warmed up at that point? White "smoke" is usually water vapor. When the conditions are right, any engine will make it. Bluish white smoke is unburnt fuel and can happen normally when the engine is really cold.
Either way, that doesn't look out of the ordinary at all to me.
it normal. i hauled a load to illinois last year in january. got up at 5 am to leave and it was -30 w/ wind chill, -10 w/o. had truck plugged in all night and when i cranked it up, it looked like a steam engine should have been under the hood with the way the exhaust looked.
