Calvin Harris Big Tipper On Music Video Shoot

Calvin Harris and his production crew are generous tippers ... according to the captain of the yacht featured in his new "How Deep Is Your Love" music video.

The production crew chartered the million dollar vessel for 6 hours to film the vid ... which, by the way, stars a very hot Gigi Hadid. We're told it cost $1000 an hour, and Calvin's team left a $1000 tip for the captain and crew. 

Then again ... that's around 18%, but still respectable.
