Specialist Footage

Our footage collection includes a vast number of video clips shot using specialist techniques, which although stunning in their own right, also give us insight into what is otherwise not visible to the naked eye.

We have more than 20,000 clips to choose from, with hundreds of new submissions uploaded to the website each week.

Astronomical Imaging footage uses sensors capable of detecting infrared or ultraviolet radiation rather than visible light. Many astrophysical processes are better seen at these wavelengths when compared to visible light.

CT Scan uses a moving beam of X-rays to generate numerous slice images of the body, which are then combined by a computer to form a 2D or 3D model.

Earth Observation Satellite Data – there are a huge array of satellites orbiting the Earth, measuring everything from temperature to sea surface height to plant cover to atmospheric water content to pollutant levels.

Endoscopy footage uses a standard camera attached to a thin flexible fibre-optic tube, which allows filming inside the body.

High Speed footage captures images at a higher frame rate than they are intended to be played back, therefore slowing down the action.

MRI Scan uses a powerful magnet and pulses of radio waves to image body tissues. It is particularly useful for distinguishing between fat-rich and water-rich tissues, both in healthy and pathological cases.

Optical Microscopy uses a series of lenses to provide a greatly magnified view of small objects such as tiny organisms, protozoa or cells.

Scanning Electron Microscopy uses a beam of electrons to scan over the surface of an object, building up a 3-D model of the surface of tiny objects such as cells.

Schlieren Imaging uses a focussed light source half-blocked by a sharp edge to image density differences in air. The edge blocks half the light, which causes density boundaries, such as shock waves, to appear as dark bands on the image, creating stunning scientifically themed footage.

Thermography uses a sensor that detects infrared radiation rather than visible light. Warmer objects emit more infrared energy, allowing temperature differences to be seen.

Timelapse captures images at a lower frame rate than they are intended to be played back. This has the effect of speeding up action, allowing footage to show, for example, the growth of plants.

Ultrasound uses the echoes from high-frequency sound waves to image internal structures. The sound reflects particularly from boundaries between dense and less dense structures, especially the walls of air or fluid-filled spaces.

UV Fluorescence uses ultraviolet illumination rather than a flash or other light source, which causes some material to fluoresce. Fluorescence means the UV light is re-emitted as visible light, revealing structures invisible in normal light.

X-ray uses high-energy electromagnetic radiation to produce a silhouette of internal tissues on a sensitive medium behind the subject. Dense tissue such as bone absorbs more X-rays than less dense tissue like fat, so bones show up as underexposed (bright) areas on the negative film.
