Slow Shutter Time-Lapse & Drive-Lapse Tutorial from RigWheels on Vimeo.
Using slow-shutter time-lapse photography techniques in video and film production is nothing new per se however, the advancement of camera technology and mounting devices is making capturing these dynamic shots easier then it has ever been, if you know what you're doing.
Slow-shutter time-lapse produces unique and very different results than ordinary time-lapse because it allows the movement in the image to blur (to varying degrees) depending on how much blur is desired for the shot.
Ordinary timelapse can have a staccato or jumpy feel to it so to produce a higher quality shot with more artistic value we’re going to slow the shutter down.
