Every other Wednesday we present a new video, so join us to see the truth laid bare...
Sample clip showing “Vasodilation” taken from the David Barlow Film Archive. Film category, Microscopy : Blood flow in capillary beds.
Vasodilation increases blood flow to peripheral tissues by expanding small blood vessels and allowing greater flow of oxygen and nutrients to be delivered through the capillary network. In humans it is also used to regulate temperature by allowing increased flow to the skin (flushing) which gets rid of excess heat. The opposite process, vasoconstriction, results in cold hands and feet.

Elements and Textures
David Barlow is a scientist and cinematographer. He has devised a number of scientific techniques for filming microscopic and endoscopic set-ups to achieve optimal visual results. David works to expand the archive of scientific film he has been compiling for 20 years. He also takes commissions to create visual effects sequences, specialising in complex simulated reconstructions of real phenomena on a miniature scale. He uses models and composites to cross the boundaries of scale and create special effects shots for high end TV documentary production.
