Coming to you from Think Media, this helpful video tutorial will run you through the basics of exposure settings for video work, as well as why an ND filter is so useful for filming. If you are a photographer, you are likely already familiar with how your shutter speed, aperture, and ISO work together to create the overall exposure and their individual effects on the image.
